I have movable office partitions that come with a 8 wire 4 circuit whip. I want dedicated neutrals for the 3 circuits feeding the partitions and all ungrounded conductors must deenergize per NEC 605.7. Is it ok for 1 ground wire to be used to serve the 3 circuits feeding the partitions, or do I need a ground wire for each circuit?

You can use one equipment grounding conductor as long as it is sized for the largest branch circuit that is run to the office furniture.

When you say you have dedicated neutrals are you referring to one neutral per circuit? If so, than 605.7 wouldn't apply since you will not have a MWBC. Regarding the EGC I agree with Raider, only one is required.

Agreed. Think of it this way: each shared neutral requires a handle-tie.infinity said:

We call this a super neutral. Its typically 3 #12 feeds (black, red, blue) with 1 #10 neutral (the super neutral) the larger neutral is if some one screws up the phases or its a 120/240 single phase circuit. Then there is 1 #12 black/white strip and 1 white/ black strip. Then there are 2 grounds 1 #12 green and 1 #12 green w/yellow strip. The separate grounds are if some one wants an isolated ground but either can be used as a ground separately. Any help?
