Connecting a portable power generator to your home’s main wiring panel can be very dangerous if you don’t follow available neutral ground diagrams and instructions. The only danger-free way to connect a portable power generator to your main panel is to have a transfer switch installed by an electrical contractor that is licensed to do so. This transfer switch moves the power from the power lines of the utility company to the power from your portable generator.
When you’re connecting your generator you must never plug it directly into any standard household outlet. This could bring utility power lines back to life and cause injury or death to utility personnel or neighbors. Each individual appliance should be connected directly to the generator, although you must be careful not to overload the generator. You can seriously harm your appliances doing so. What you’ll want to do is prioritize the equipment and appliances you want to run and only hook up to the portable generator those you think you have to have during a power outage.
Your generator should never run indoors or in any enclosed area. The carbon dioxide build up can be deadly and unnoticeable until it’s too late. It should operate out of doors in an area that is dry and well ventilated, where it won’t be directly exposed to any precipitation, and where it has no danger of sending fumes back into the house through any air intake. Look carefully at any diagram of your home to assure this is the case.
Make sure your connections to your portable power generator are safe. The cords must be rated for outdoor use and heavy duty. They must have a wire gauge that can handle the load from the appliances. Neutral ground is crucial.
