Your residential generator wirings will determine how you transfer your electric load during a utility outage. There are several options available to you, allowing for a smooth and automatic transfer, or a manual one if this is what you prefer. Choosing the right option can help you keep your back up power supply both safe and legal.
Some individuals with residential generators do not have transfer switches in place. Instead they feed power back into the utilities with their generator. This is called islanding and it is both illegal and dangerous. It is also not a very effective means of managing your energy resources.
Because the line is not anticipated to be live by most neighbors and utility workers, there is a huge potential for electrocution. Because all of the homes that are on your electric grid will have access to your supply, it can also become rapidly depleted. Rather than facing huge fines, lawsuits and other issues it is always best to search for a better solution.
An automatic transfer switch turns the generator on just after the utility failure has been detected. The utilities are immediately connected to your alternative power source. When the power failure is corrected, the generator gets turned off and the power supply is transferred back to the main. The generator will not immediately cease action however. It will take several minutes as the generator completes its cool down mode before the system is entirely quiet.
For those individuals that want a bit more control of circumstances during a power outage it is possible to purchase an automatic switch that also has a manual mode. By keeping the transfer system in manual mode, you can determine when to transfer the residential generator wirings or electrical load. Online researching can help you find a transfer switch that suits your needs and fits your budget.
