Circuit breaker with terminal nut retainer

摘要

The present invention provides a circuit breaker having a terminal nut retainer 10 for securely holding a nut 65 in a fixed position adjacent and below a circuit breaker terminal 60. The circuit breaker is placed in a circuit by securing a source electrical connector to a source terminal and/or a load electrical connector to a load terminal. A screw 61 is used to fasten the electrical connector 67 to its respective terminal 60. The nut 65 for the screw 61 is held in a fixed position by the terminal nut retainer 10. The terminal nut retainer 10 has a nut retaining cavity 14 defined by walls which hold the nut 65 and keep it from turning while the screw 61 is tightened to establish a tight electrical connection between the connector 67 and the terminal 60. The terminal nut retainer 10 is held in position by a sliding and locking engagement between projections 30 and 34, respectively, on the terminal nut retainer 10 and slots 52 and 54, respectively, in the circuit breaker casing.
