These are high-end fasteners for electrical applications, so your IHI Connectors® (AKA International Hydraulics Inc) 7700 St. LaROcque Member. Loose lugs create a high-resistance connection to the bus bar, and electrical resistance in metal causes heat. It would be very difficult to come up with enough torque to distort them. This is a common way to use these washers, especially when assembling bus bar. 2018 Tiffin Allegro Bus 45OPP 03-25-2022, 07:56 PM High Road Travelers. 6 x 8. Ampacity of the bus bar selected must then be verified by checking Table 1. Control and signal circuits may require different torque values, and the manufacturer should be contacted for guidance. S. What are the torque requirements for busbar hardware? Torque levels for busbar bolt sizes are Ampacities were calculated using a nominal conductivity of 99% IACS and should also be applicable to other coppers with the same electrical conductivity. The GE breaker specs do not call out a torque value for the connection to the buss bars which does seem reasonable since it is very dependent on what it is being bolted to. Inspection Following a Short Circuit; Torque Values for Electrical Connections. Instead, the Codes Homeline Load Centers are compatible with Homeline 1” circuit breakers and feature tin and copper plated aluminum bus bars. Most of the SQ QO 200 amp stuff is 250 in lbs. 0 32.
