Cutting 8 AWG THHN Electrical Wire to Length

Cutting 8 AWG THHN Electrical Wire to Length

We all know that buying more of something usually gets you a better price per unit in almost every industry out there. In the wire and cable industry buying more will definitely get you a better price but it may not always be the best option for you or your company.

Many suppliers of 8 AWG THHN electrical wire have started to cut it to the exact length the customer needs in order to avoid waste on each job. Yes, the installer or contractor will get a better price per foot if they buy 500 feet instead of 120 feet but how much waste will that yield? It's going to be different for each job but once that spool of 500 feet gets down to 80 feet it's going to be much more difficult to find a use for it. The spool might sit there for quite some time and, in the mean time, you have to order another spool of 500 feet in order to prepare for the next job you have.

Buying online has become much more common than 5 years ago. Many online suppliers of 8 AWG THHN wire will let you buy to the exact foot you need on their website. Some even offer free shipping to anywhere in the USA once you hit a certain dollar amount. The main thing to be sure of is the length of your run because there's nothing worse for you or the supplier when you wind up a couple of feet short and need to return the spool you have in order to get the right length.

8 AWG electrical wire is typically used by electricians, contractors and installers. The most common colors are black, red, white and green. Green is usually designated as the ground wire instead of a bare copper ground because when it's being used outdoors it needs the protective insulation to resist water and gasses that it will come in contact with.

Suppliers that will cut 8 AWG electrical wire to length for you will most likely cut Romex®, UF-B cable and MC cable to length as well. The fact is that suppliers cut multiple lengths per day while contractors only order a couple of times per month. The higher turnover allows the suppliers to have minimal waste at the end of each month and be able to supply their customers with exactly what they need. It makes life easier for the installer to be able to price the full job without having to factor in waste.

Who Manufacturers 10 AWG THHN Electrical Wire?

Who Manufacturers 10 AWG THHN Electrical Wire?

Most end users of THHN electrical wire do not have the ability to buy directly from the manufacturer due to the amount of dollars they will spend per year. Many consumers think if they can buy enough quantity of one particular wire at once that they will be able to purchase it directly from the manufacturer but that's not true. Manufacturers want to see their distributors buying on a consistent basis throughout the year and commonly hold them to minimum quantities or dollar amounts per year.

Distributors are customers of the manufacturers and constantly compare pricing between them in order to offer the best pricing themselves. Therefore, distributors can possibly have an inventory of the same wire from two or three different manufacturers. Be sure, when judging the actual material from different distributors that it's actually material from different manufacturers instead. Most distributors of electrical wire will let you know, especially if you ask, who the manufacturer is because they have no fear of you buying it direct.

10 AWG THHN electrical wire is one of the largest volume items in the industry because it's used to bring power from the telephone pole to the electrical box of buildings and homes and it's used to bring power from the electrical box to the outlets, lights and appliances in your home.

Back to the initial question, who manufactures 10 AWG Electrical wire?

Southwire, Republic Wire, Cerro Wire, Unified Wire and Cable, Western Electrical Sales and many more. They all manufacture a great product as I've seen samples from each. Southwire is the powerhouse of the industry and have created and branded the name Romex® which is an indoor electrical cable manufactured with THHN wires inside of a PVC jacket.

I have not ever seen too much of a price difference between the different manufacturers because in this industry with thick coppers strands and minimal insulation it's difficult to vary the pricing. Other cables such as portable cord and extension cords has extra flexible copper strands, PVC insulation, fillers and a tough rubber jacket made for protection and flexibility. In that case manufactures can be faster or more efficient in five different areas that will affect the pricing compared to about two areas for THHN wire .

You can ask direct questions to your supplier about who the manufacturer is because will be sending you the product with the Brand name printed on the jacket anyways. If you find a manufacturer that you seem to like better than others you can also request that it come from them each time you buy.

Electrical Wire 12 AWG VS PVC Wire 12 AWG

Electrical wire and PVC wire and quite different for specific reasons due to the application they are applied to. Electrical wire is more commonly used by electricians, contractors and installers where PVC is more commonly used in electronics and wire assemblies for stereos and appliances.

Why do they need to be different if they're both 12 AWG wires?

That is correct; a 12 AWG wire is a 12 AWG wire before the insulation comes into play. Bare copper 12 AWG will carry the same amount of current if it's a solid strand of copper or multiple strands that equate to the same amount as the solid version. The stranding options are how it becomes more or less flexible which can benefit certain applications more than others.

Think about building a harness yourself with stiff electrical wire that's more commonly used to snake through walls and conduit. It would make it much more difficult to deal with when crimping, terminating and soldering. Therefore, manufacturers have made it more flexible by decreasing the size of each strand and winding them together to form the same size wire. More often than not PVC wire has very flexible options. A standard 12 AWG PVC wire has 65 strands while a standard electrical wire 12 AWG has 19 strands.

The same benefit is given to the installer with a less flexible copper wire. The installation process becomes much easier with a stiff wire that does not lose its form or get bunched up. A PVC wire being pushed through conduit would not work at all.

Another characteristic of THHN electrical wire is that the insulation has been tested and approved to be used in outdoor weather conditions where PVC wire can not. Since it's so common used outdoors and in conduit engineers have found all kinds of chemicals, gasses and moisture that come in contact with it each day that the insulation will need to resist in order to last.

PVC wire has voltage and temperature concerns that are much more important than resistant environmental conditions. PVC wire will come in 300, 600 and 1000 volts along with temperature options of 90ºC, 105ºC and 200ºC because there are many applications in ovens, appliances and electronics that each have different heat variations during the life of the wire being used.

Remember that 12 AWG copper will always carry the same amount of current but the insulation is what determines where the wire can be placed and how it can be used in different applications.

2 AWG Copper Electrical Cables That Are Direct Burial

2 AWG Copper Electrical Cables That Are Direct Burial

There are many types of electrical cables out there with different types of insulation that allow it to be exposed to certain environmental conditions. Do not forget, these cables also need to withstand certain voltage, amperage and temperature requirements depending on the application as well.

As for direct burial cables that have 2 AWG wires in them; a Tray Cable is the most universal type of electrical cable used in the industry. It's basic, it's round and it can be placed in conduit or buried directly in the ground if you so choose. The best part about it is the pricing. Copper weight can not be changed no matter what happens, so if you're looking for three 2 AWG wires in a jacket that can be protected from underground use then the insulation and the jacket will be the only differences in your search.

If you need a single conductor 2 AWG wire without an additional jacket you can use USE-2 solar panel wire. Do not assume that it can only be used for solar panels because a 2 AWG copper cable is a 2 AWG copper cable. You're looking for sufficient protection to use it underground and the insulation on a USE-2 cable has exactly that.

Some cables that get confused about direct burial are SOOW and Type W. SOOW is oil and water resistant and approved to be used outdoors but not in conduit or underground. Type W is an SOOW cable on steroids as it's bumped up to 2000 volts from 600 with an additional rubber EPDM jacket for added protection. However, it still can not be used in conduit or underground. The added protection is intended for industrial use on industrial job sites where machines will be running over the cable day to day.

So if you're looking for a direct burial single wire you should use USE-2 and if you're looking for a cable with multiple 2 AWG wires in it then you should use Tray Cable. Talk to your supplier about your application to make sure you're buying the correct electrical cable. There is also different flexibility options you might want to consider for a slightly higher price.

You may be able to slightly downgrade the cable to save money and spend a less amount on conduit if your object is to save money. There are many scenarios that can be worked out so make sure you at least have the discussion with a professional before diving into an underground cable.

Highly Efficient Electrical Control Panels Used For Monitoring Instruments

Highly Efficient Electrical Control Panels Used For Monitoring Instruments

Remember those colorful buttons and displays that layer any typical 80's B Villain's den? And how the typical bald, scar adorned, rouhnneck would press the red button at the slightest hint of the hair-suit mad scientist Dr. X?

Well, that is the Control Panel, a very good example in fact. In the simplest of words, a Control Panel (also known as Electrical Control Panels, Power Distribution Boards, Service Panels and Panel-boards) is a flat surfaced, horizontal or vertical board covered by control or monitoring instruments that is used to supply electricity to the countless applications and equipment involved in a system or project. Control panel are seen in a variety of sizes, shapes specifications and encompass a wide range of types. Right from a normal mechanical panel with a few buttons and displays to complex and intricate modern sound and consoles – all fall in this category.

These panels are seen in almost every industry or wherever any project is being executed. A primary element, it facilitates in keeping a track of all the process at a single desk. Originally, these panels were equipped with switches and push buttons and other analogue instruments but now these are being replaced by automated and touchscreen displays.

It consist of a capital console and several sub panels, along with a numerous indicator lights. The fuses and the circuit breakers are integrated in the Console. In the contemporary versions, transformers are omitted to facilitate in the current supply at a voltage lower than that of the main supply. This type of panels are highly efficient, esp in situations where several equipment with varied power requirements are amalgamated in a single circuit.

Although in this century innovation and cutting edge technology, a wide variety of Electrical Control Panels are available with countless technical integrations and digital displays, a typical control panel consist of the following parts:

  • Housing – The outer cover that houses all the switches, displays and lights. It is generally fabricated from plastic or metal coated with insulated paint, so as to eliminate all opportunities of short circuit or electric shock.
  • Main Disconnect – A very integral part of any Control Panel, the central power controlling switch of the unit unit. Its function is of critical importance in case of any short circuit or overload.
  • Circuit Breakers – As the Main Disconnect is switched on, the power flows through it to several circuit breakers. These little components function by tripping down automatically in case of power overload or fluctuation. Thus, these devices eliminate the risk of excess overheating of the unit, which may lead to fire hazards.

Today, it is mandatory that almost all Electric Circuit Panels available in the market are stamped QC Passes by their respective manufacturers. Still a few factors that should be checked before purchasing it can be summed up as:

  • Resistance to changing weather.
  • Safety standards.
  • Temperature bearing capacity of the controllers.
  • Quality of circuit breakers.
  • Inclusion of voltmeter and integrated main switch fuse unit.
Practical Energy Conservation Tips To Observe In Every Household

Practical Energy Conservation Tips To Observe In Every Household

Every household needs to conserve energy. This is something very elementary. Even if you're filthy rich, you can not be irresponsible. You may be able to afford exorbitant electric rates, but others can not. But more importantly, while you're being wasteful, the environment is suffering the adverse consequences. How is this so? Well, not all of us may be aware of this, but electric companies typically use fossil fuels to provide us with energy. These include oil, coal, and natural gas. The by-products are very harmful to the environment. So if we do our part and conserve, we kill two birds with one stone. We lower our bills while helping Mother Nature!

Like a lot of other things, energy conservation should also start at home. If we make a habit out of energy saving practices, this will help a great deal. Some of these tips are not that new. We have actually been aware of them for a long time. The only difference is that we do not practice them religiously. So starting today, let's re-evaluate these simple but important energy conservation tips.

The first one is to utilize your home appliances carefully. Turn them off when they're not in use and remember to unplug them as well.

Home appliances such as refrigerators, washing machines, dryers, air conditioners, and heaters eat up around two-thirds of energy consumption at home. But if you unplug them whenever they're not in use, you're saving a great deal in terms of usage. Secondly, be more practical when using your heaters and air-conditioners. For example, during the winter months, set your thermostat at a standard temperature for daytime and just adjust it at night. Also, insulate your home well so that you will not be using too much heat. Thicker curtains, rugs, and covers will help a lot. Moreover, do not forget to clean your air filters in hot-air furnaces.

Third, replace devices in your home that consume too much energy. One example would be incandescent bulbs. Replace these with compact fluorescent ones. Also use larger ones so you will have less bulbs around the house. Another would be to wrap your water heater in an insulating jacket. It can save 1100 pounds of CO2 per year for an electric water heater or 220 pounds for a gas heater. Lastly, try to use energy-friendly means of transportation whenever you can. For example, on weekends, you can refrain from using the car without it's absolutely necessary. Use your bike or take a walk because it's good for your health, too!

How to Choose the Right Air Conditioners for Your Home

How to Choose the Right Air Conditioners for Your Home

As a homeowner, you always want the best stuff in your house and that includes appliances that make your place more comfortable to live in, like air conditioners. But your desire to equip your home with the finest things money can buy will all be for naught if you do not know how to pick out which ones are right for you and your family. This is why learning how to choose the best AC unit that would fit your abode should be your top priority.

What to look out for

Home appliances were born out of necessity and it's exactly what you should keep in mind when you buy air conditioners. It's all about what you need more than anything else which is a mentality that could help you save more money than just buying on impulse or going straight for the top brands in the market.

The first thing you should consider is the amount of space you have in an area where you want to install an air conditioner. Some people do not know it but size matters when it comes to cooling down or warming up homes. It's because AC units are quite on how much power their motors are capable of producing which is dictated by size of the area they're installed in; big rooms need more power while small air conditioning systems are sufficient for tiny spaces.

After determining how much cooling power your home needs, it's time to decide on the type of air conditioners that would meet them. There are basically 4 kinds of AC available today; window, portable, centralized, and ductless split system. Each one has a unique application as well as both perks and disadvantages.

Window type. This kind is ubiquitous in old houses and buildings which is why it's also considered the traditional air conditioner. It's easy to install and there are many brands being sold at dirt cheap prices. But the downside of using it is power consumption especially for older models.

Portable. As its name suggests, this air conditioner is light weight and do not need to be installed in a fixed location. It's great for people who are just renting apartments or condominiums short term and do not want all the hassle that goes with AC installations.

Centralized system. For big homes with plenty of rooms, this is the ideal setup. Using ducts that connect all areas of the house to a single AC unit, owners get total climate control within their homes. It can be cost to use this but it's also a good way to save on energy by properly distributing cool air in parts that have high human traffic.

Ductless split system. Among air conditioners online, this is the most quiet and less obtrusive kind. It can be installed automatically anywhere as only a small hole is needed to let copper tubing pass through to connect the compressor outside to the main unit inside. This is ideal for people who want to add air conditioning to an area but do not want to have a total renovation.

Solid Bare Copper 18 AWG Cut to Length

Solid Bare Copper 18 AWG Cut to Length

Wire and cable comes in all shapes and sizes including cut to length and possibly stripped insulation. Such things should be connected by an ISO9001 certified company because they are forced to perform checks that, if done incorrectly, can negatively impact the company as a whole.

Being an ISO9001 company means that the company has been checked and certified as having a system in place to stop errors from meeting or correct them immediately. Not doing so will give the company a “bad grade” with the certification audit team that checks on the company annually. They come into the company, check the process in place and push for continuous improvement through the organization to be sure correct product is always being sent to customers.

Cutting 18 AWG bare copper is quite simple to perform but let me give you an idea as to how an ISO9001 certified company may perform the action. First, the sales person will double check and sign off on the revision of the specification sheet given by the customer to be sure everything is accurate. Second, the production manager makes a first article sample for the rest of the production team to view during the cutting process. Third, during the process there is a certain amount of times the assembler must verify the length while cutting to make sure the machine cutting it did not have any hiccups along the way. Finally, the production manager checks and signs off that a percentage of the pieces were done correctly before boxing them and sending them to the customer.

As you can see having your bare copper cut by a company that's already ISO9001 certified will near guarantee that it will be done correctly. If not, however, the company also has it in their policy to completely refund and / or fix the mistake that was made. Whenever mistakes are made they're documented for commonality to other specifications that may relate. Continuous improvement will be connected at that point.

Solid copper 18 AWG can be cut to any length you need by most suppliers. It can also come on 100, 250, 500 and 1000 foot plastic spools for you to cut as you need. Ordering at the right price is always a good idea, but getting correct product each and every time can hold quite the worth itself. Also, knowing that the company you bought it from is ready to fix the mistake immediately is something that might be hard to come by.

14 AWG Bare Copper Ground Wire – Uninsulated Solid Strand

14 AWG Bare Copper Ground Wire – Uninsulated Solid Strand

A ground wire is typically a bare copper strand without insulation that will ground the application being powered. Romex® cable is common in households sending power from the electrical box to the different outlets and larger appliances through your home. The ground wire is just one of the wires inside of the Romex® cable that will be discussed.

Romex® is a cable that was created in order to send three of four wires from point A to point B at the same time rather than sending them individually. It looks much more attractive to have a single cable traveling through the ceiling of the basement than having a mess of wires going every way.

Romex® 14/2 is a cable made up of two 14 AWG THHN wires along with a 14 AWG bare copper wire used for grounding purposes. The two THHN wires come in black and white with a nylon coating over the insulation to resist moisture and oils. It can also come with an additional red wire if you need three wires for the application.

If you need an insulated ground wire because your application requires the cable to run outdoors, even for a portion of the run, then you'll need MC cable. MC cable, or Metal Clad, has an insulated green ground wire instead of a bare copper ground so that it can also resist outdoor weather, gasses and oils that it may come in contact with.

A bare copper 14 AWG wire has an outer diameter of.064 inches, a carrying current of 5.87 and a fusing current of 166. The electrical properties should help you, or your electrician understand what size of bare copper you'll need for the application you're running. 14 AWG copper has about 81 feet in one pound which is worth about $ 3.50 in today's scrap market.

You can take any metals you have to a metal scrap yard in your area to get cash for the total weight that you have. You'll get about 30 percent less than the NYSE pricing for copper which does not include the fact that they may need to remove any insulation off the wire you bring. Straight bare copper wire will yield the best rate at any metal scrap yard.

Make sure you save all of your extra copper wire so that you can cash it in later. It's similar to saving your change in a jar until it grows into a decent amount of dollars.

Uninsulated 16 AWG Bare Copper – Solid Copper Gauges

Uninsulated 16 AWG Bare Copper – Solid Copper Gauges

There are many types of 16 AWG wires with and without insulation that are used in the electrical field. A few types of the uninsulated versions are solid bare copper, stranded bare copper, tinned copper and silver-plated copper which each come without any insulation at all. A few types of insulated versions include PVC, PTFE, TGGT and irradiated PVC which each resist certain moistures, chemicals or even outdoor environmental items such as water and gas.

Bare and tinned copper are both very popular types of 16 AWG wire in a solid strand without insulation. It has an outer diameter of.051 inches, a carrying current of 3.69 and a fusing current of 117. It has about 128 feet in one pound which is worth about $ 3.50 if you try to trade it at your local scrap yard. Copper is quite high in 2012 compared to 5 years ago so it's worth saving every piece of copper to actually trade it in for cash down the road.

Most suppliers will have the ability to cut 16 AWG copper to any length you need whether it's 1 inch or 1000 feet on a plastic spool. Normally, when cutting bare copper to 1 inch the supplier will expect an order for 100 to 500 pieces instead of just a few. However, I absorb, as the consumer, you might be able to get whatever you need as long as you ask the sales person you're speaking with.

The insulated versions of 16 AWG wire are usually cut and stripped upon request of the customer. A flush cut does not make too much sense because the copper strands will need to be shown in order to fit them into the application and get an electrical current. The wire cutting machine will be set to cut the wire to 6 inches and strip 1/8 of an inch from both sides so that the strands are showing.

Many customers also request that the copper strands be dipped in tin sold so that they do not fray when being packed and shipped to your location. This will also help in the soldering process because the additional tin on the ends will adhere directly to the new solder on the application. Be sure to ask your supplier if they are ISO9001 certified because it's an industry standard for companies with value added services to perform quality checks during and after the production process. This will assure you that the product you receive is either correct the first time or will be corrected if it was done incomplete or wrong.
