Burial of #4 BAG wire.

Look at 300.6(A) and 300.6(A)(3).

Yet Article 348 says FMC shall not be used underground or embedded in concrete.

It’s not FMC, it is a cable assembly like AC or MC.

:lol:

I am curious to about this armored ground wire... Would the armor jacket have to be terminated in an AC connector? it seems to me this would be pretty difficult outside of a panel... Also I thought that#4 did not require physical protection.. perhaps I am confusing my codes. What installations would require an armored ground wire?

According to the web link it is #6 or #8. See it a lot on older services. You would use an ac connector in the panel and a ground clamp for the rod or water that also has the strap for the armor.

Good question what it is listed as and what you can do with it. Here is the AFC web page that really doesn't tell you much:

As for connectors and ground clamps, we talked about that before awhile back.

Where is 'like AC or MC' in the code book?

Look at 320.2 and 330.2

Both AC and MC are to be fabricated with insulated conductors. So BAG can't be either one of those. What's that leave?

This customer is a nuisance. Seems that she would complain how a wire is run to code concealed in a wall.

Holding the BAG!

I think it is just a bare wire with armor on it. not a NEC cable assembly at all. If so it can be used anywhere a single bare wire can be used IMO.

Thinking the same thing.

Back in probably the 40's they did use a version of that with an insulated conductor (RW or RHW?) that you still run into every once and a while. Used to see that buried out to a ground rod.

UL 467 7.10 requires the armor to be terminated.

I have seen that stuff going to cold water ground but I don't think I have seen it buried. Not many ground rods needed in those days ( metal water pipes). I doubt it would hurt it any to bury it.

I’m currious,
is it ran somewhere close to shore like under a house on stilts? So wouldn’t the aluminum portion corrode fairly rapidly?

Hi everyone. My apologies for my late reply to everyone's helpful comments. The "BAG" wire is a copper grounding conductor within a steel armored jacket. Looks exactly like MC. Here in LA it's used as the GEC on 99% of the new home/panel upgrade construction. It really looks terrible sometimes, I try to be as inconspicuous as possible when I plan the run. LADBS requires two ground rods and cold water. So, these GEC runs can get quite long.
In the end, I just moved the GEC and my customer was happy with it. She is my neighbor, have to keep the neighbors happy! Thanks again for all the input.
