When changing out molded case breakers in our switchgear the mounting is usually copper studs. I have been trying to find a torque chart that includes copper studs and bolts but have not had any luck. Also some use flanged nuts and some use nut,flat, and belleville. If any one knows where I can find this information it would be much appreciated.
Thanks.
