Wiring Recept.

[Alwayslearningelec]

Curious as to how you electricians would figure this. I guess you would have to know if you had to run seprate neutrals or you could handle tie, correct? That would impact what/how you pull your cables.

Lat's say it's a MC cable job and you have to have separate neutrals.
There are some recept. next to each other on same circuit and some adjacent that are on diff circuits.
How would you pull cable to recepts next to each other on diff ckts.
I'd figure a pipe from panel to location/box right above/near that wall with several ckts and drop down with MC cable.

Would you use multiple neutral mc cable or separate mc cables for each circuit which seems wasteful.

Thanks

You could use greenfield (fmc) and make your own cable that's how I would do it

Conduit homerun(s) to a box and separate MC cables for each circuit. Receptacles on the same circuit would get an MC jumper from the nearest box on that circuit (i.e.-A-27 on the left side on your print).

Ok, that's what I would usually consider but seems like you'd use more MC cable than you'd need to running a dedicate from each recpt that's a diff ckt.

Yes but it keeps thing more simple especially if the box is very close. Besides with separate neutrals you'll need special MC cable.

is there are real difference between MC and FMC with some wires in it?

Not really. MC has its own EGC, FMC will often require a wire type EGC. Derating applies to both.

No it doesn't but it's easier to make up what you need

Why special MC if you pulling a separate 12/2 for each ckt as you indicate?

On that note. If you use FMC you'll have to pull a H/N/G for each 120v 1p-20a ckt, correct?

I meant that if you pulling a home run cable with say 3 circuits, that would require 6 or 7 conductors depending on the cable type.
