Don't be left in the dark. With the GenInterlock ITE-200A Interlock Kit, you can safely back feed electricity into your home from your Gould, ITE, or Siemens electrical panel and portable generator. A generator interlock kit is a device to allow safe back feeding of a home through a portable generator during power outages. This eliminates unsafe generator back feeding situations that could potentially electrocute electric power company workers or destroy the generator. This electrical accessory is installed on the front cover of the breaker panel. It consists of two sliding metal or plastic plates held together by three bolts. When moved down, the plate blocks the generator back feed circuit breaker and allows the main breaker to remain on. When moved up, the generator back feed circuit breaker may be turned on but the main circuit breaker is blocked and will remain off. As a result, electricity from the generator cannot travel through the panel and back into the wiring on the street. No one ever expects to lose electricity. Be prepared by ensuring your home electrical wiring is equipped for safe generator use with this interlock kit.
