I was asked a question from a former collegue......It appears he was getting an inspection from the architects and engineers on a job he is doing. He had a wire trough above a panel with all the branch circuits hanging there and the engineer said " we have a problem". He proceded to tell my old friend that each "hot" had to have its own neutral, or if the neutral is shared it must be "upsized". He also said this was in 2008 code. I always thought up to a,b,c phase could share a neutral. Please advise
