Why is a generator interlock so important?

  • With aging electrical infrastructure and frequent severe weather, the power to your home frequently trips, which affects thousands of families nationwide. However, this can be very dangerous to use the utility and generator at the same time, it may be causing circuit loads to burn out or generators to burn out, etc..
  • So the National Electric Code Requires a Generator Interlock Device When Powering a Breaker Panel with a Generator. Failure to Install an Interlock Could Have Fatal Consequences to a Lineman or Utility Worker!

How It Works?

  • 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.

What is a generator interlock?

  • Generator lock consists of two sliding metal plates held together by three bolts.

  • It is a device just manual slide up and down interlock plate to allow safe back feeding of your home through a portable generator during power outages, preventing utility and generator supplies from being ON at the same time.

  • It’s used to direct the generator power to any circuit in your house safely in the event of an unexpected power outage, so that you can use electricity normally.
  • NOTE: Only qualified personnel should be working on any panel box. An amateur should never open or work on a panel box. Please follow all rules and regulations of the National Electric Code.

Generator Breaker Retainer Straps

  • There are some plays in the connection between the generator breakers and it may be some movement. Zip ties go around the generator breaker and adjacent breakers to hold them solidly to the panel. This helps keep the generator breaker from shifting.

This product is great for people who don't know much about electricity. My wife doesn't know much about it so this is a must in case I'm not home at time of power outage.

Very nice generator interlock, quality built, and good looking design. Nice andceasy installation with all included hardware. Works as it should and much more affordable than adding a transfer switch.

I’ve got an older Westinghouse breaker box. This installation was easy and straight forward. It works great and only allows the main or generator breaker to be in the on position one at a time, for safety. Don’t skip this step! It’s unsafe and possibly illegal. Buy this kit and safeguard yourself, your property, and others.

Kit allowed for a relatively easy hook up from my generator to my distribution panel. Only unexpected issue was that the “knockout plug” in the box had to be drilled out, unlike a typical gang box where the plugs can be removed with a screwdriver. Interlock Switch Plate worked perfectly and was easy to install.
