Abstract
In an electrical switchboard, an aluminum run-in connector is formed in an L-shaped configuration having a vertically oriented segment and a horizontally oriented segment extending inwardly to a termination where electrical connection to a device terminal can be made. A bolt clamps the vertical segment in electrical connection with an aluminum riser bus and, at the same time, fixtures the connector with a horizontal projection of the vertical segment protruding through an opening in the riser bus. The projection is then welded to the riser bus along the edges of the opening therein to complete a bolted/welded joint between the connector and the riser bus.
Claims4
In an electrical switchboard, a bolted/welded electrical joint for electrically connecting an aluminum riser bus with an electrical device installed in a switchboard cubicle;
- said joint comprising, in combination:
- A. an L-shaped run-in connector fabricated of aluminum having a horizontal segment extending forwardly to a termination facilitating electrical connection with a terminal of the device and a vertical segment;
- B. a rearwardly extending projection formed with said vertical segment;
- C. means forming an opening in the riser bus;
- D. a bolt clamping said vertical segment in electrical connection with the riser bus with said projection protruding through said opening in the riser bus;
- and
- E. a weld electrically joining said projection to the riser bus along the edge of said opening therein.
