How would you handle...

[mstrlucky74]

If you had a note like this and almost every receptacle was separate circuit and you were using MC cable? You would have to use #10 MC and not #12 even though they are just asking for neutral to be #10.

I would ask whether they mean the neutral of MWBCs that supply separate single-pole circuits (as opposed to a single multi-wire load).

Good point. Also I never seen all receptacles in office space on separate circuits. About 150. odd.

Wait, does the panel schedule show 150 different circuits for receps ?

I would first ask them what is a "separate circuit outlet'?

Yes, about 4 different panels.

One outlet on it's own circuit( 1p-20a breaker). no?

Sounds like a guess.

I don't know what it means which is why I would ask the question. Assuming you're correct why would you need a #10 neutral for a 20 amp circuit with a #12 ungrounded conductor?

Not a guess based on drawings. Each receptacle( well 90% of them) has it's own circuit.

Still makes no sense why you would have a #10 neutral and a #12 ungrounded conductor in a 2 wire circuit. It's either a mistake or someone doesn't have a clue.

The supernoodle was in the coppercabals best interests....trade rags were lousy w/non linear loads and harmonic editorials a few decades ago

True RMS meters sold like hotcakes

But the world turned ,few jobs were spec'd out for it, and now were stuck with antiquated labels

Is this something bidding, or do you already have the project? I also don't understand why that note is in there, but smells like there's going to be a spec line or general project note not allowing MC cable if it's already this over-engineered and calling for about 150 dedicated recepts in a typical office space.

Old specs. is my guess.
some of the specs we get are out of the late 80's and early 90's.

Bidding. MC is allowed.

Where is that post about, eng./contractors again?
would love to hear back on the RFI, "too late to change bid the documents!".
Then you come in thousands over and the lowballer gets the job and an extra!
