Abstract: A splicing assembly, for facilitating splice connections of electric wires, includes a housing made of nonconductive material, and a terminal assembly attached to an inner surface of the housing. The housing includes a base, and a cover placeable in covering relation over the base. The housing cover is removably attachable to the base. The housing base and cover define a protected space therebetween, and also define an inlet and an outlet therebetween for respectively receiving wires in opposite ends thereof for connection of the wires within the protected space. The housing base may include one or more mounting blocks, for supporting metallic conductors thereon. The mounting blocks, where used, are generally non-conductors. The terminal assembly includes at least two metallic conductors attached to the base, which may be provided as generally flattened metal bars. The terminal assembly also includes adjustably tightenable clamps for clamping wires against the metallic conductors.
