Neutral Conductor

[sbutler]

NEC Forum Gurus,

I want to place 13 conductors in one conduit (6 single-phase, 120V circuits; 6-hots, 6-neutrals (no shared neutrals) and (1)-ground). Concerning the neutral, I interpret 310.15(5)(a) to apply where I do not have to count the neutral conductor as a current carrying conductor when applying Table 310.15(B)(3)(a). Does anyone see an issue with this?

Thanks for any and all responses.

Steve

Only shared neutrals of MWBCs are not counted. You have 12 CCCs.
If you had three 3-wire MWBCs you would have only six CCCs.

Ok. Because I have 6 individual circuits with their own neutral, they all have to be counted as CCC's?

Forgot to add, it is not against code to install 12 CCC's in one conduit but I must adjust per Table 310.15(B)(3)(a)?

Thanks,

Steve

Yes.
