Tap-Off Box Connection to Bus Rail

Two Step Process insures Safety and Electrical Integrity

Step 1: Mechanical Connection

  • All grounding connections engage & seat directly to the open channel
  • Top Mast connects mechanically to the bus rails. Set screws then insure alignment to rails. Rail design prevents backwards installation.

Step 2: Electrical Connection

  • Once Top Mast is mechanically secured, the cam action lever seats all electrical contacts against the phase bussing. Once energized, it locks down into position.
