What Should I Do If The Bolts On The Cable Terminals Are Loose?

If you discover loose bolts on cable terminals, shut off the power immediately to prevent electrical fires or equipment damage. The standard repair process involves inspecting the connection for heat damage, cleaning the contact surfaces, and re-tightening the bolt to the manufacturer’s specified torque settings using calibrated tools.
