Abstract:
Electrical apparatus comprising:an electrical structure operable utilizing either single or three phase electrical power;a terminal structure having a line side portion operative to selectively receive either single or three phase electrical power from a source thereof, and a load side portion having first and second electrical connectors associated therewith;power receiving circuitry coupled to said electrical structure and having a third electrical connector releasably mateable with either selected one of said first and second electrical connectors; androuting circuitry interconnected between said line side portion of said terminal structure and said first and second electrical connectors and being operative, without altering said power receiving circuitry, to:(1) route single phase electrical power to said electrical structure, via said power receiving circuitry, when said third electrical connector is operatively mated with said first electrical connector and single phase electrical power is being supplied to said line side portion of said terminal structure, and(2) route three phase electrical power to said electrical structure, via said power receiving circuitry, when said third electrical connector is operatively mated with said second electrical connector and three phase electrical power is being supplied to said line side portion of said terminal structure.
