#10 Neutral

[lordofthisworld]

I’m figuring home runs from the panel to be MWBC then when I get near the loads I’m going to run 12/2 mc for each circuit .

So u are sharing neutrals? Do u need to?

EMT home runs from panel to home run boxes in the areas of the loads then branch out with MC from there to the loads

We can share neutrals but they must be #10 so since we run #10 home runs from the panel im going to run MWBC home runs out to various areas with boxes then branch out with 12/2 mc to all loads

They do sell tri-circuit cable, 3 hots with each hot having its own neutral, Black, red, blue.

The advantage of doing that (using all #10's and MWBC's) is that you can run a larger conduit and stuff it with more conductors. The derating won't affect your 20 amp circuits until you exceed 19 circuits in a single raceway.

Typically I run EMT with MWBC's out of the panel to a point closer to the outlets and then transition to MC. In that case just 12/2 MC is typically used. Yes if you run MC all the way home you would need to meet that requirement for a #10 neuter.

A few comments on the handle ties. Note that you only need handle ties and NOT common trip for MWBC's. Three pole common trips are a lot more expensive than 3 single poles and a handle tie. The problem is some brands do not offer a three pole handle tie. When I use handle ties a don't install the center rod so someone can pull off the tie easily if needed to operate a single handle .

You don't use a 10D nail for handle tie? 10 AWG solid also works great.

Those were certainly used on more than one occasion or so I understand.

The handle tie rule for MWBCs is a very dangerous rule IMO, I will not comply, or at least I will make so the tie can be easily removed.
