US Patent 9698578 Slotted bus bar for electrical distribution

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.
