IMPORTANT: When locating the 400A switch, verify that the minimum diameter for the loop of the cable between the switch mechanism and handle mechanism is not less than 16 inches.Any reduction to the diameter of the bend loop for the cable will reduce the efficiency of the cable system, and create additional drag and friction within the cable conduit.
IMPORTANT: Verify that the cable assembly does not interfere with any mechanical and moving parts. Keep the cable conduit a minimum of 1/2" from all heat sources and current carrying terminals, fuses, transformers, etc.
