Abstract

A modular power distribution system is ideally suited for use in modular buildings of the type in which prefabricated building modules are constructed at a manufacturing factory and shipped to a remote building site where the modules are interconnected to form the complete structure. The modular power distribution system includes a primary power distribution panel positioned in one of the building modules and is adapted to distribute power from the utility service to the building modules. Modular power distribution units positioned in each of the building modules are adapted to distribute power within a respective building module. The primary power distribution panel has a plurality of main circuit breakers, each of which is electrically connected between the utility service and one of the modular power distribution units for limiting the maximum current through a respective modular power distribution unit. Each modular power distribution unit also includes a secondary power distribution panel which is physically and electrically interconnected with an associated service distribution unit. The secondary power distribution panel includes a plurality of secondary circuit breakers, and the service distribution unit includes a plurality of modular electrical connector first portions. Each of the modular connector first portions is connected to receive power through a different one of the secondary circuit breakers. Each building unit also includes a plurality prewired electrical fixture units. Each of the prewired electrical fixture units includes an electrical fixture, a modular electrical connector second portion, and a plurality of electrical conductors extending between the electrical fixture and the electrical connector to transmit electrical power therebetween. The connector second portions are electrically and physically mateable with the connector first portions to electrically interconnect the prewired electrical fixture unit with one of the secondary power distribution panel.
