How to ground hot water heater element in cooler?

[chrismac676]

I've installed a hot water heater element in a cooler that I plan to use as a sous vide machine. Any ideas on the best way to ground this? I'll always have it plugged into a GFCI breaker, but my understanding (please correct me if I'm wrong) is that grounding is still essential.

FYI I also plan to add an enclosure around element terminals.

Thanks in advance.

Bump... Someone has a good answer on this one - help appreciated so I can cook tomorrow!

I guess the easiest way would be to sandwich a piece of sheet metal under the mounting nut and ground to that with a ring terminal and self tapping screw.

If your enclosure is metal, make sure it is bonded well to the element nut and attach the ground to the box.

Seems like I saw someone take a small sheet of copper from a hobby store and cut a hole in it with a holesaw and used that as a connection point for the ground. It's somewhere buried in the forums I'm sure.
