Generator Safety

Standby Generator Safety: Disconnection Switch Essential

If you keep a standby portable generator for emergencies, or if you decide to install a whole home generator, you must use an appropriate transfer switch to prevent electricity from flowing from your generator system back out onto utility power lines. Back feed of electric current is a dangerous and potentially deadly concern for line workers. AEC and the National Electric Code require either an automatic transfer switch or a Main Breaker lock-out switch to be installed for generator use.  When regular electric service is interrupted or restored, these devices provide for the safe use of a generator.  A switch can also prevent power from flowing back in and destroying the generator. Use of these types of transfer switches is a requirement of the National Electrical Code.

All generator equipment must be operated in a well-ventilated area outside the home. Make sure it’s out and away from your garage, doors, windows and vents. The carbon monoxide generated is deadly and for health & safety reasons, all homes using generators should have a carbon monoxide alarm or detector. For portable generators, use a heavy-duty extension cord to connect electric appliances to the outlet on the generator. Start the generator first before connecting appliances.
