Depends on what type of clock you have. Alot of clocks/timers/controllers DONT have a grounding LUG on the board or cabinet.

You only see these types of grounding requirements once you step up to commerical controllers and most all 2 wire controllers. It will have a lug specifically for tieing into for running a heavy copper ground wire and copper ground plate or rod for the unit.
