UL Listed Generator Connection Cabinets

The Berthold Electric Generator Connection Cabinet (also known as a “tap box” or “generator docking station”) is a quick-connect station for a portable generator or load bank. Once it’s installed, you’re ready for quick, easy, and safe connection of a portable roll-up temporary generator to provide backup power in an emergency or during a planned outage.

For facilities that already have on-site backup power, use a Generator Connection Cabinet for additional redundancy during permanent generator repair or maintenance, and/or for annual load bank testing.
