Good afternoon,
I've encounter a situation that I need help understanding. We have two parking lot lights that share the same 220V source. When trouble shooting the reason for them not being on I had found there is only two wires. After asking a few other tradesmen why, there was no neutral I got the same responce "just because". If 120V circuit requires a neutral wire and 277V requires it, Why doesn't 208V or 220V? Is this normal or to code. What determines it the have a neutral or not?
Thank you in advance
