About Generator Interlock Technologies, LLC


Millions of homes & businesses, during the course of a year, are forced to rely on generators or green energy as a means of back-up power supply during main grid power outages. Fortunately today, many have discovered the safe, reliable, legal means of connecting a back-up power source to their existing household electrical panel with the help of the Interlock Kit Team!

In 2003 hurricane Isabel struck the eastern coast of the United States, knocking out power to millions in a few short hours. Engineer & Master Electrician, Douglas Albertson, of Richmond, Virginia, set out to develop a device that would create a safe connection between a portable generator and electrical panel. This manual transfer switch would lock out the main breaker in a home’s existing electrical panel and allow for the portable generator to safely power the home through a back-feed generator breaker; it would also meet National Electrical Code requirements – and be cost-effective and convenient for homeowners.

Today, Generator Interlock Technologies LLC (GIT), designs & manufacturers code compliant mechanical Interlock Kits for the latest electrical panels, as well as models for panels more than 50 years old! All Interlock Kits produced and sold by GIT are made of stainless steel and laser cut, in Richmond, VA, where products ship out.

We are proud to have proven products! Wyle Labs – now Element is the original testing lab, granting Interlock Kit certification to retrofit to UL 67 Panelboards. Today, the Interlock Kit line is tested by Eurofins – MET Laboratories, twice annually, for UL compliance.
