Generator Safety

A generator can be a wonderful tool during an outage, but it can also be extremely dangerous. Please contact PEC at 888-554-4732 before installing a generator so we can make sure it is properly sized and connected.

When using your generator, keep the following safety tips in mind:

  • Know your generator! Read all the information on installation, safety and maintenance, and follow instructions regarding maintenance and testing. When a generator is not properly installed, it can "backfeed" through the Co-op's transformer and produce an output of 14,400 volts on our distribution power line. As a result, a line crew working on our system would be put in danger.
  • For everyone's sake, isolate your generator from the Co-op's power lines. This means you should connect appliances or other devices directly to the generator with the appropriate-sized cords. If you connect the generator directly to your building's wiring, a transfer, double-throw switch is required to separate your generator from the Co-op's system.
  • Take care when fueling your generator. Never try to refuel the unit while it's operating. Avoid spilling gasoline or other fuels on hot components.
  • Provide adequate ventilation and air cooling for the generator to prevent overheating and the accumulation of toxic exhaust fumes. Do not install your generator in a basement or any closed area. Exhaust gases contain carbon monoxide, which is an odorless, invisible and poisonous gas.
