Is this device grounded?

[TOOL_5150]

The danger i see is if we remove this dimmer from the box and it had a fault with screws removed there is no grounding. And even with the mounting screws there is a chance it might not be grounded. I VOTE NO.

You should have the circuit off if you are removing the device.

The crow is tough and stringy.






Mark, it's over, big font will not change that.

FWIW I never attach a bonding jumper to switches mounted in metal enclosures.

Yes you should but then you will turn it back on to do your voltage checking. If that yoke is hot you will get hurt.

Hey but I'll eat it, and man enough to admit I am... But big font does help make it taste better.... It's like a sauce....

I think the proof is in the pudding.

I vote you build 1 small wall, with two openings like you have shown in your diagrams, and forceably fault the dimmers and see if one is "effectively" grounded or not.

Let us know what happens.

he may not be around to let us know.

he should write a note to have someone pass along the results.:grin::grin::grin:

Alright - just for you... I'll hit both with a welder current and see what blows open first... Hows that?

Counting on 2 loose screws for a ground is about the same as just sticking the ground wire threw a hole in the box. Chances are high it will work but neither are NEC accepted. This is hack work, slam your trunk shut and go home cause it works. Unless it is self grounding it need a grd wire to that yoke.

Is a dimmer switch considered a snap switch?

I think someone needs to take a peek at 404.9(B) ....

I voted that it was grounded but I went back and looked at the picture. The screws are loose so it is not grounded.

Ya think.

What are you doing using actual written code to back up your argument anyway.

That apparently does not matter....

Rather than worrying about interpreting the code, the correct approach would be, would I be satisfied with this installation in my house for my family? Or you could just stick a #14 in the hot side of an outlet while holding the other end in your hand, then touch the device in question with your other hand, and find out if it?s grounded or not.
