Bus duct joint employing lightly-loaded multiple-point electrical connector

摘要

A single-bolt joint having louvered contact strips interposed the bus bars and conductor splice plates for improved electrical connection under low insertion forces is tightened to become a solid connector assembly prior to attachment to the bus bars of a first bus duct and requires no additional tightening after insertion of the bus bars of the second bus duct. Expansion of the bus bars is accommodated at each joint without special apparatus.
