404.9 (B) question

[POWER_PIG]

Hi Folks! I have question concerning installing a regular 15a switch in a surface mounted 4 square and using an industrial / RS type metal cover. Does 404.9 ( B) mean I don't have attach an actual bond wire to the switch yoke?

Thanks,
Pig

Yes, that would be correct.

That's correct

I 'm on page with the others!

To add, I feel it's best to attach the EGC to the device.

Very prompt response! another reason I love this forum, and thanks. I thought that was to be true, but was asked today by another electrician and wanted to make sure I wasn't steering him in the wrong direction.

thanks again,
Pig

Switches do not required a bonding jumper for these types of covers. Receptacles won't require them either under the 2008 code if the cover has indented corners like a cover for a 1900 box.

They do under the 2005 NEC.

Thanks for the '08 code info. But I never installed a bonding jumper for switches on raised covers anyway. At least now it's code legal.

Do you mean receptacles? That's true, since those types of covers are already listed for bonding the device. The new code verbiage spells it out directly. Saves someone the time looking up the listing of the specific cover.

Here is an example for receptacles.

Do you mean receptacles?

No I mean for switches, 404.9(B) requires that metal face plate to be grounded.

I can see your argument for the bonding jumper but the switch is grounded to the box by the cover mounting screws. The requirement is for the cover to be grounded and the cover mounting screws provide this function. This is really not much different from mounting a switch to a mud ring.

Rob, Read (1) to 409.4(B) and notice that only applies to switches mounted to boxes (like a mud ring) not mounted to covers.

A switch mounted to a raised cover has to have a wire EGC running to it.

Bob, not that I disagree with you, but they allow a receptacle to to be installed in a raised cover without a pigtail, so why in the world would a switch not be allowed?

No one has put in a proposal that made it?

Thats what I was thinking...

Here is a pic for what 404.9(B)(1) is actually saying, for anyone following along at home.. Personally, I dont see much difference in a mud ring vs a raised cover as far as bonding is concerned.
