Portable generators are often used for a backup power supply in the event of an emergency power outage. Improper use or installation of an electric generator can cause property damage, serious injury, or even death.
Please keep the following safety and installation guidelines in mind when installing or using a home generator.
When considering the purchase of a generator, it’s a good idea to have an electrician evaluate a home’s electrical system for proper grounding and polarity, and then install a generator transfer switch. The homeowner connects the generator to the transfer switch. From there, the generator’s power is fed into the service panel and to the dedicated circuits that have been specifically wired to be powered by the generator. The transfer switch also prevents electricity from feeding back into the electrical grid that powers your neighborhood. This protects utility workers from encountering unexpected current coming from your house – a dangerous condition known as backfeed. In addition, backfeed could severely overload the generator and damage the unit. It is required that installation of a transfer switch and wiring interconnecting the generator to the home’s electrical system be inspected by a State electrical inspector.
