Hello Everyone
Currently dealing with a situation that the lighting panel 480/277 4W is tied to 480V, 3P,3W distribution panel upstream, and there is no available neutral from the source panel to use in the 4W lighting panel and feed lighting at 277V. What would be the best solution to provide neutral to the lighting panel board? Is adding 480/480 V isolation transformer with neutral on the secondary will do the work? Or Should we bring neutral wire from another 4W panel board? please advise the code compliant and cost effective way to resolve the issue?
