ABSTRACT:
An electrical busway plug-in brick for mounting on a busway housing includes openings which allow access to bus bars running along the length of the housing. Barrier members are preferably positioned across the openings to restrict access of fingers or other similarly sized objects through the openings, while allowing electrical contacts to be made therethrough. The plug-in brick preferably includes a lockable cover which deters unauthorized access to the openings of the plug-in brick. The openings may extend unequal distances through the plug-in brick in order to provide increased creep and strike distance which prevents electrical arcing. The plug-in brick may be mounted on the busway housing by release pockets which prevent destruction of the plug-in brick upon a short circuit by allowing the plug-in brick to be detached from the housing.
