Let's see if I can describe and ask this so that it makes sense to you all.
As I read the NEC 2002 Handbook, on a 208/120 3 phase circuit, coming from a 100 amp sub-panel with 12 breakers, it is proper (ok) to use one neutral for set:
C 5 these use one neutral
C 9 these use another neutral
C 15 these use a third neutral
Having said that, can I use the following set up?
B 3 this pair uses one neutral
A 7 this uses the second neutral
C 11 this uses the third neutral
B 15 this uses a fourth neutral
I hope this makes sense to you all.
