Abstract
The housing has therein two wire inlet/outlet openings overlapped by opposite ends of a removable, generally L-shaped knockout cover, which has in one end an access opening registering with one inlet/outlet opening, and in its opposite end a knockout plug which covers the other inlet/outlet opening, but which can be removed if both inlet/outlet openings are to be used. A wiring chamber is formed in the housing in communication with the inlet/outlet openings by a removable right-angular cover element which cooperates with the housing walls to form a chamber which is triangular in cross section.
