Limit Switch

[wirestu]

Greetings all.

Have a limit switch on a water valve with only two terminals for the switch contacts. The metal enclosure does not have a ground screw or terminal. It is an old limit switch that was connected with metallic sealtite. We have reconnected with non-metallic sealtite and the consultant has questioned that there is no ground termination. Any thoughts on what we should do.

Thanks in advance.

I would use a metallic raceway that's suitable as an EGC.

Yes

If the flex is necessary, I have seen a short conduit nipple on the switch, sealtite connected to short nipple, ground clamp on nipple, external bonding conductor around sealtite.

Sounds like an easy fix to me. At least it should have been.
