If you own a back-up generator to supply your home or business with power during an outage, it is critical for your safety and the safety of our employees that your equipment is properly installed. Improperly installed generators can cause fires and feed electricity back into the power line, endangering the lives of your neighbors, the public and PSNH line workers.
- It is a requirement that a transfer switch be installed to prevent back feeding electricity into the PSNH system. A transfer switch ensures that the PSNH power supply coming into your home or business is disconnected before you connect and operate your generator. Likewise, when returning to PSNH services, a transfer switch will make sure your generator is disconnected before reconnecting to the PSNH supply. Please consult with a licensed electrician regarding the installation of an appropriate transfer switch.
- Never Operate generators inside of a home, garage, basement, crawl space, carport, enclosed/partially enclosed space, or near doors and windows.
- Store fuel for generators in properly labeled containers kept away from living areas and fuel-burning appliances.
- Carbon monoxide detectors with battery backup should be used in nearby enclosed spaces to monitor levels.
- Make sure that extension cords used with generators are rated for the load, are free of cuts or worn insulation, have three prongs and preferably one with a ground fault circuit interrupter (GFCI)
