Generator Safety

ELECTRICAL SAFETY AND GENERATORS

CAUTION!!!

 

If standby generators are being used, or the purchase of one is anticipated, be sure the unit is properly installed by a licensed electrician and approved by the local electrical inspector.

If the standby unit is to be wired through the fuse box or breaker panel, it must be isolated from the Co-op's service system, by means of an approved disconnect switch.

Improper use of a standby generator could cause dangerous backfeed on the Co-op's system and could cause death or injury to our linemen, working to restore power, or other individuals that may come in contact with a downed power line.

 

PLEASE DO NOT PUT SOMEONE'S LIFE IN DANGER!

Preventing Electrocutions Associated with Portable Generators Plugged Into Household Circuits

When power lines are down, residents can restore energy to their homes or other structures by using another power source such as a portable generator. If water has been present anywhere near electrical circuits and electrical equipment, turn off the power at the main breaker or fuse on the service panel. Do not turn the power back on until electrical equipment has been inspected by a qualified electrician.

If it is necessary to use a portable generator, manufacturer recommendations and specifications must be strictly followed. If there are any questions regarding the operation or installation of the portable generator, a qualified electrician should be immediately contacted to assist in installation and start-up activities. The generator should always be positioned outside the structure.

When using gasoline- and diesel-powered portable generators to supply power to a building, switch the main breaker or fuse on the service panel to the "off" position prior to starting the generator. This will prevent power lines from being inadvertently energized by backfeed electrical energy from the generators, and help protect utility line workers or other repair workers or people in neighboring buildings from possible electrocution. If the generator is plugged into a household circuit without turning the main breaker to the “off” position or removing the main fuse, the electrical current could reverse, go back through the circuit to the outside power grid, and energize power lines or electrical systems in other buildings to at or near their original voltage without the knowledge of utility or other workers.

 

Effects of Backfeed

The problem of backfeed in electrical energy is a potential risk for electrical energy workers. Electrocutions are the fifth leading cause of all reported occupational deaths. Following the safety guidelines below can reduce this risk.

 

Other Generator Hazards

Generator use is also a major cause of carbon monoxide (CO) poisoning. Generators should only be used in well ventilated areas.
