Generator Safety

To avoid the accumulation of deadly carbon monoxide, only use a generator outdoors. Never use a generator indoors, in an attached garage, a basement, or a crawl space. Avoid using a generator in a partially enclosed inhabited space, even if it is ventilated; opening doors and windows or using fans will not prevent carbon monoxide build-up. If placing it outdoors, make sure the generator is far from a home's doors, windows and vents.

In addition, the storm has led to an increasing number of customers using generators to power their homes and businesses. CL&P reminds customers that if a generator is installed incorrectly to a home's wiring, it can cause power to "backfeed," or flow back into the power lines, creating a dangerous situation for the public and for our line crews who may be working nearby. To avoid this situation, have a qualified electrician connect the generator with a transfer switch, so that it is not connected directly to your home’s wiring.

Portable Generator - Electrical permit required for the transfer switch wiring.

Standby Generator - Permits required:
  • Electrical
  • Fuel Gas Piping
  • Building Permit if Required
