Electrical mechanical lug torque specs.

We are experiencing a lot of failures of insulated lug connectors on motors lately and are being told by the lug mfgs to torque them. Mechanical lug 1 hole 1 barrel straight copper 14 to 6 awg 3 16 in. Loose lugs create a high resistance connection to the bus bar and electrical resistance in metal causes heat. How does that relate to electrical lugs.

Each of our parts has the opportunity to have a separate torque associated with it. Tightening torque in inch pounds. Our website allows the users to find the specific information sheet they need. Tightening torque values for ilsco mechanical screw connectors.

A critical concept in understanding bus lug torque specifications is the fact that the pressure of the lug connection has more to do with lowering the resistance of the electrical connection than the size of the lug itself. Tightening torque in inch pounds. Mfr cxs35 36t c view product. Sometimes it could be compression but in this case it is torque.

Sometimes there are multiple torques for the lug. Internal socket size across flats inches. Tightening torque values for ilsco sockethead screw connectors.
