Model CBS-1 and Model CBS-2 Circuit Breaker Stab Sets allow connection to virtually all MEGGER circuit breaker test sets. Their use eliminates the significant losses that occur if leads are used to connect the breaker under test to a test set. These stab sets allow testing of drawout style metal-clad breakers. (Cables must be used when testing molded-case circuit breakers or other devices that will not connect directly to the stab.)
