So the situation is I have a 277/480 panel feeding into a mixing box, from there i have multipul conduits ran into a lighting control panel. The person who origionally installed the system pulled the hots down one conduit and switchlegs down another leaving the neutral parked in the mixing box to pick up lights later on. With the new rules in 402 i know you do not have to bring the neut down to a normal switch, but can you leave it behind and run the hot and switchleg down the the lighting control panel in sperate raceways?

Sounds like a Good RFP (request for proposal), you have conduit, Maybe I missed it , and that's not an exception not to bring down a neutral.

You can look at it as if you touch it you bring it up to Code, depends on your cycle year but I doubt your before 05'.

402??? At the point in the wiring system you described, fixture wires should not be involved. I'm thinking you meant 404. :happyyes:

You didn't say whether enclosures and conduit were ferrous (steel) or nonferrous. If ferrous, that'd be a violation of 300.3(B).
