disconnected for any reason it must be reconnected for safety.
The typical connection utilizes two external tooth lockwashers to sandwich the
conductor ring terminal against the connection base and the tightening nut/screw. All
hardware must be replaced. Retighten connections to 2.3 N·m (20 in-lb).
