Abstract

Abstract An electrical power center for recreational vehicles comprising a cabinet which is adapted to be framed in the interior structure of a recreational vehicle and which has a circuit breaker box and a power converter unit mounted therewithin. The power converter unit may be conveniently removed from the cabinet for servicing. This converter unit includes a stepdown transformer and means for rectifying the output of the secondary of the transformer for supplying low voltage d.c. to various d.c. loads in the recreational vehicle. The converter unit is connected to the circuit breaker box by a flexible, detachable input cable to supply a.c. power thereto and is connected to the d.c. loads by flexible output cables for supplying low voltage d.c. thereto. These input and output cables are of sufficient length to permit substantial removal of the power converter unit from the cabinet. The output cables connected to receptacles which are removably mounted in a side wall of the cabinet for interconnection to the various d.c. loads by conventional plug and cable connectors.
