Portable Generator

Before using a generator, read the operating instructions carefully. Connecting a portable or recreational vehicle (RV) generator to home wiring can cause problems. Ideally, appliances should be plugged directly into a generator, using extension cords if necessary

If you must hook a generator to the main electrical panel, it is very important to disconnect your home from GRU's electrical system and install a transfer switch. Contact a qualified electrician for this. If you do not disconnect your home, power can flow into the outside utility lines and injure unsuspecting crews working to restore your electric service. It also can damage your generator and the electrical appliances in your house. It might even injure a neighbor if power from your generator flows along common lines to another house

When using a generator, also make sure there is adequate ventilation to avoid carbon monoxide poisoning.

Q. How should I hook up my portable electrical generator?

A. Appliances should be plugged directly into a portable generator, using extension cords if necessary. For your safety, run portable generators outside the house so the generator gets proper ventilation. Check the manufacturer's recommendations and follow them for proper use and load. If you have any doubts, consult a licensed electrician.

Only a licensed electrician should attempt to hook up a generator to the main electric panel of a home or business. If you improperly connect to a main panel, power can "back feed" from the generator, including RV generators, into utility lines and injure a neighbor, property or utility crews working to restore service.

Q. How many appliances can I connect and run from my portable generator?

A. Consult the manufacturer's instructions. Each generator has a rated wattage, which provides a limit for how many appliances it will safely power. Add together the wattage of different appliances and do not exceed the manufacturer's total rated wattage for the generator.
