Conductors connecting receptacle and switch circuits to lighting and power home-run
boxes in finished areas may be multi-wire, steel jacketed, type ?AC?(hospital grade only)
or ?MC? cable, consisting of one (1), two (2) or three (3) No. 12 AWG copper ?THW?,
?THHN? or ?THHN/THWN? insulated phase conductors, each with dedicated insulated
neutral conductor (no multi-wire shared neutrals allowed) and one (1) full sized (No. 12
AWG minimum) insulated ground conductor

Do you read that as a dedicated neutral and ground for each circuit? I only have 6 circuits on this job but I was curious.

I read that as a dedicated neutral for each circuit, and on ground conductor for the cable, not a dedicated ground for each circuit.

I assume that you've posted this information from a spec. No according to the code you don't need a separate neutral and EGC but sounds like that's what they're paying for.

Thanks infinity. Didn't something just change in the 11 code regarding neutral conductors and branch circuits?
