Abstract:
1. An electrical power distribution system for a multi-tenant building structure supporting roof-mounted solar panel or wind turbine generators comprising: a weatherproof box enclosure adapted to be secured on one of an outside wall and roof location of, said structure, said box enclosure including: a plurality of input terminals adapted to receive alternating current voltages corresponding to direct current voltages generated by said solar panel or wind turbine generator; a terminal block having a plurality of identified input and output terminals adapted to distribute the alternating current voltages to individual tenant units within said building structure; a multiple pole control unit having individual input and output terminals; a plurality of net metering units individually coupling the output terminals of said control unit to the identified input terminals of said terminal block for monitoring individual electric usage at each individual tenant unit; a plurality of GFCI over-current protection devices individually coupled between said alternating current voltage receiving input terminals and the input terminals of said multiple pole control unit; a normally open override switch within said control unit, actuable when closed to disconnect the distribution of alternating current voltage to individual tenant units coupled to output terminals of said terminal block; a voltage sensing relay and/or shunt trip relay within said control unit actuable to close said normally open override switch in response to monitored alternating current voltages falling below a predetermined level; and whereby said normally open override switch is additionally controllable to disconnect the distribution of alternating current voltages to said individual tenant units in response to actuation of an emergency shut-off switch located at a structure ground level.
