A torque limited screw is used to secure a conductor to an electrical connector. The screw has a torque limiting feature between a head and a body of the screw which must be overcome by force to break the head free from the screw body. The screw assembly includes a threaded body configured to be releasably coupled to a coupling portion of the connector. A head of the screw assembly is joined to the body via a neck portion which under a specified torque applied to the head fractures to break the head away from the body seated in the connector and securing the conductor. In one embodiment, the screw includes a plate spaced from and coupled to the threaded body for contacting the conductor. The plate is rotatable relative to the threaded body when the threaded body is coupled to the coupling portion of the connector.

A bus bar for electrical power distribution may be an elongated extruded metal bar having slots extending the entire length thereof. The slots may be of T-shape cross section, each with the channel opening through a face of the bar. Bolts are arranged with their heads captured in, and slidable along the length of the slots to any desired position. The bolts may have threaded stems which extend from the head through the channel of the T-slot in which its head is disposed and beyond that face of the bar through which the associated T-slot opens. Each stem is adapted to threadably receive a nut for clamping, supporting or connecting lugs to the bar. The bus bars can be mounted on insulating support members.
