Circuit interrupters and electrical enclosures with rejection features

摘要

A set of circuit interrupters and electrical enclosures that are configured to permit an electrical enclosure having a current rating to have connected therewith a circuit interrupter having a current carrying rating no greater than the current rating. However, a current interrupter having a current carrying rating less than the current rating of the electrical enclosure potentially may be connected therewith. Such electrical interruption equipment employs threaded studs on bus bars that are of varying sizes and/or are separated by varying distances in order to resist an electrical enclosure having a current rating from being electrically connected with a circuit interrupter having a current carrying rating greater than the current rating. Alternatively or additionally, the circuit interrupter and/or the electrical enclosure may have interference elements that physically interfere with the mounting and/or the electrical connection of a circuit interrupter having a current carrying rating with an electrical enclosure having a current rating less than the current carrying rating.

主权项

1. A circuit interrupter having a current carrying rating, the circuit interrupter being structured to be installable in electrical connection with an electrical enclosure having a current rating at least equal to the current carrying rating and being structured to be non-installable in electrical connection with an electrical enclosure having a current rating less than the current carrying rating, the circuit interrupter comprising:
an electrical interruption apparatus having a current carrying rating and comprising a housing and one or more of:
a receptacle having a dimension, the dimension being structured to enable the receptacle to receive therein an elongated conductor of electrical enclosure having a current rating at least equal to the current carrying rating, the dimension being structured to resist at least one of:
reception into the receptacle of a conductor of an electrical enclosure having a current rating less than the current carrying rating, andattachment of the circuit interrupter to a conductor of an electrical enclosure having a current rating less than the current carrying rating;a pair of receptacles that are spaced apart a distance, the distance being structured to enable the pair of receptacles to receive therein an elongated pair of conductors of an electrical enclosure having a current rating at least equal to the current carrying rating, the distance being structured to resist reception into the pair of receptacles of a pair of conductors of an electrical enclosure having a current rating less than the current carrying rating; andan exterior portion which is structured to be interfered with by an interference element of an electrical enclosure having a current rating less than the current carrying rating and which is thereby structured to resist electrical connection between the circuit interrupter and the electrical enclosure having the current rating less than the current carrying rating, the exterior portion being structured to be non-interfered with and to permit electrical connection of the circuit interrupter with an electrical enclosure having a current rating no less than the current carrying rating.
