Model CH-HASP Fits Westinghouse, Challenger, Thomas & Betts and other panels which have a two pole vertical throw main mounted approx. 4 1/2" above the top branch breaker and the column of branch breakers offset approx. 1 1/8" to the right as shown.
 
The gen breaker will occupy the two TOP positions in the branch breaker column and there MUST be a 1" BLANK position directly below the gen breaker. This interlock allows you to keep the main breaker hasp located on the right side of the main.
 
This kit is not yet a full production run kit, so all components are not our signature blue anodized color. It is precision CNC machined from solid aluminum billet however, and looks very professional and fits very well. The kit includes everything necessary to complete the installation including all hardware, the correct size drill bit, name brand thread lock compound, a full warning placard set, and clear installation instructions.
 
All of our interlock kits are proudly made in the USA!
