ABSTRACT:
An improved single-pole electrical connector is disclosed. The connector has a base electrical connection at one end and a pin-and-collet type electrical connection at the other end. A nonconductive mounting base is used to attach the connector to an electrical distribution panel. An electrical cable (e.g., an electrical supply line) is connected to the base electrical connection. Another electrical cable (e.g., from an electrical load) is connected to a pin, which is inserted into the collet. A collet nut is tightened to provide a secure electrical and mechanical connection between the pin and collet. The nonconductive mounting base provides a secure attachment to the distribution panel and insulates the electrically conductive parts of the connector from the panel. An insulating boot may be used to cover the pin and collet side of the connector in use.
