An auxiliary terminal connector adapted for use with a circuit breaker panel into which one or more pluggable circuit breakers are plugged comprises a support base which supports one or more electrically conducting bus connectors. Each bus connector corresponds to a pin from each set of signaling connector pins of the pluggable circuit breaker and is adapted to electrically connect together all these corresponding pins such that signals from them are conveniently bused together and can be accessed from a single or multiple positions on the auxiliary terminal connector. The bus connectors are tulip-shaped in cross section and are adapted to maintain good electrical contact with the signaling pins. They are made of resilient, electrically conducting material which provides a biasing component against the signaling pins when these are plugged in. Manufacturing tolerances and other deviations are accommodated by slits provided in portions of the bus connectors which permit some independence in the biasing of portions of the bus connectors against associated pins.
