Abstract: A universal electrical connector is incorporated into the electric power distribution network of a motor control center, switchboard, or switchgear between vertical bus conductors and the power line inlet. The connector in the form of substantially a single metal casting is configured to connect the power line with the control center internal electrical distribution conductors without requiring additional connectors.

Abstract: A bracket assembly for releasably attaching a pilot panel to an electrical enclosure, the bracket assembly comprising: a bracket adapted to support the pilot panel in an open position and a closed position, the bracket including a hook extending form the bracket; a hanger bracket attached to the enclosure, the hanger bracket including a first flange and a second flange depending from the first flange, the hook releasably engages the first flange to support the pilot panel in the closed position and releasably engages the second flange to support the first flange to support the pilot panel in the open position.

Abstract: A defeatable interlock mechanism for an electrical equipment enclosure requiring a circuit breaker to be tripped before opening includes a support platform having an operator handle stem operably connected to the circuit breaker, an interlock slide plate slidably positioned along the support platform and having a keyhole-shaped slot for receiving a door interlock pin therein, and a lever operably connected to the interlock slide plate and configured to defeat the interlock mechanism when the door interlock pin is engaged with the slot. The lever is pivotally supported at a fulcrum point intermediate the ends of the lever and extends through an escutcheon to an exterior surface of the enclosure. Movement of the lever causes the interlock slide plate to disengage the door interlock pin and allow the unit door to open even while the circuit breaker is in the “on” position.

Abstract: A draw out unit with improved drawout box and handle assembly is disclosed. The drawout box is designed to accommodate an improved terminal assembly of the present invention, which reduces the dimensions of the box, and further provides access to the interior of the box by providing an open side for allowing service of an electrtical device within the bucket thus permitting the motor control center to remain active during service. The drawout box of the present invention further includes an improved handle assembly with operable connection to a circuit breaker handle within the confines of the smaller drawout box.

Abstract: A two-part motor control center interlock arrangement has a handle support plate and interlock slide positioned on an interior of the control center door operating by insertion of a tapered pin on the door interior within a key-hole slot on the interlock slide. The elongated slot of the key-hole slot automatically compensates for any tolerance accumulation between a circuit breaker handle, an interlock operating handle and the control center access door.

Abstract: A circuit breaker is configured as an electric disconnect switch within a motor control center enclosure and is arranged on a functional support platform. An extended operating handle operator on the platform interacts with the circuit breaker ON/OFF handle to indicate the circuit breaker TRIPPED condition.
