Abstract
The present invention provides a modular electrical power block assembly including a plurality of ports for receiving individual modular circuits. The power block assembly includes seven separate electrical conductors, three of which are hot, two of which are neutral and two of which are ground, for providing three separate and independent circuits. The hot wire of one of the circuits is advantageously separated from the hot wires of the remaining two circuits by two grounds and two neutrals and one circuit may be shielded to prevent penetration of electro-magnetic interference from the other circuits. Individual circuit modules are adapted to be received within individual ports of the power block for selectively completing one or more of the three independent circuits provided by the power block assembly. The contacts extending from the individual circuit modules are arranged to engage only preselected wires within the power block assembly for completing a predetermined circuit. Although the circuit modules are mechanically interchangeable with respect to the ports on the power block, they are not electrically interchangeable and will establish the same circuit in any port in whic…
