ABSTRACT:
An electrical junction box having a plurality of holes into which are inserted hole cushions which are fitted to the periphery of the holes to protect electrical wires entering the junction box from the bare edges which form the holes. Top and bottom insulated cushions further protect the electrical wires from contacting interior sides of the top and floor of the junction box. Wire guards are provided which surround the insulated electrical wires to allow the insulated wires to be secured by clamping means to the electrical junction box without the electrical wires actually coming into direct contact with the clamping means.
