(901352617) 1/4-20 nuts. Use 7/16" socket. Torque to 65 in-lbs. Notice that the return bus
adapter is turned backwards in the distribution picture above. This requires that the load
return lug be connected to the adapter first, then attached to the return bus.
Secure Load and Return Cable connections to the adapter bus with provided hardware
(per cable):
(2) 841064777 3/8-16 nut
