G'day all, prefacing this by stating that all work is going to be done by a licensed leccy. Prior to that happening I'm after a bit of advice please if anyone can help.
I've got two Romar elements in junction boxes that are going into my 1V brew kettle, mounted on opposite sides. Previously it housed a single KK element with 3-pin power cord.
My question is around the grounding of these elements. From the photos and hacked-up diagram below, will the contact between the base of the element, the wall of the kettle, and the mounting screws on the element base be sufficient to be able to use one of those mounting screws to ground the system? There appears to be some sort of fibre washer supplied with the elements but I assume I don't need to use this?
I'm asking here, rather than waiting to speak to the leccy, because if this method is not appropriate and I need to mount a grounding screw/lug somewhere I'd prefer to have that done prior (hourly rate and all...).
Also I would welcome any feedback on whether my mounting method is appropriate or can be improved. For context, these will be driven by a matho's controller, using the same waterproof connectors that the controller uses for power into of the junction boxes. It just occurred to me that perhaps the silicon washer should be on the outside of the kettle for a better seal, and if that were the case then the ground circuit contacts would be mounting screw to element base to backing nut to kettle wall.
Thanks anyone for your help.
