40A 2P toggle switch

[flashlight]

Installing 40A 208V tankless HW heater for commercial bathroom.
Architect wants disconnect switch to be flush with wall. There's not
really a good place to put access door for disco in wall.

Thinking of using this:

Looks as if it would mount in 5 in. box with 1G mud ring.

Has anyone used one of these before ?

Thanks !

Looks like a good solution.
I've used similar 30 amp versions. What size condcutors are you using?

2 space loadcenter with breaker and flush cover are an option and may cost less.

Hadn't considered that, a good idea, thanks. Around here they call that a "panel-ette" : )

Rob, was going to run 2 #8's with a #10 ground.

Run is 70 ft.

Finished conduit today, lots of saddles and offsets/kicks to get there but fishtape is sitting in pipe waiting !

That switch says non grounding in the link you provided.

Would do this just to better connect the conduit run to ground.. Looks like the yoke of device goes to ground anyway even if there is not a green terminal.

I just didn't know if you noticed the switch was non grounding.

That's not an issue with a metal yoke screwed into to a metal box.

Yes, saw that before and sort of puzzled over it. Thanks for bringing
that up

The 404.9(B) requirements for a grounding apply to General-Use Snap Switches, the switch in your link is a controller.

Bob, controllers don't require grounding?

I am not saying that, all I am saying is I don't think the specific requirements of 404.9(B) apply here.

Great point.

It seems that the only way to actually ground this device (call it a controller or a snap switch) is by the mounting screws.

what about a breaker lock?

I don't think a breaker lock would fly around here. It's
a line of site disco they ask for. The NYC amendments to the NEC contain
a bit of voodoo Interesting about the grounding aspect of "controller" however,
--we ran a green #8 also, and will bond that to boxes along the way, but, yes, the yoke screws are the grounding for 40A switch.

i thought 10's were as big as you go on devices with up turned screws.....

Getting #8's folded into a box with that switch will be a chore.
