Fixed Connections

When connections using lugs or bars are made in compliance with Schneider Electric instructions (tightening torque, class 8.8 steel hardware and contact washer), no particular maintenance is required.

Otherwise, regularly check the temperature-rise points (change in color of copper or tinning), disassemble the connections, clean, and scrape the contact surfaces. Then reassemble the connections using new hardware.

Check the terminals.
