Abstract
A universal circuit breaker interlock arrangement allows two circuit breakers to be interlocked such that only one of the circuit breakers is on at one time. The circuit breakers can be interlocked, per se, or when used with an electrical motor operator or with a manual rotary operator. The slidably mounted interlock arrangement also allows interlock function between two electric switches as well as between an electric switch.
