me the apprentice vs. Fire marshall

For example a 4" sq. metal box surface mouted with raised cover can either be grounded at the box or the outlet or both.

I don't believe that's correct. The receptacle can depend on cover-to-box contact, but the box cannot.

It's EMT and no ground is pulled.

Well, why didn't you say so? :smile:

Technically speaking, our corrections were accurate: the box's bonding is not dependent on the cover-to-box contact.

Now that I think about it, you said "the box can be grounded" either way:

. . . a 4" sq. metal box . . . can . . . be grounded . . .

...so there!

Listed spring type grounding outlet. Bonding jumper not required

How does that apply to what you said???

No offense apprentice. But their are so many variations of grounding.
