480/277Y Panelboard
480/277Y Panelboard
(OP)
I have a 1600A panelboard that is fed via a 2500kva transformer that is rated 480/277v on the secondary.
The panelboard does not have any loads that need a neutral.
Is it required to run the neutral conductor from the X0 of the transformer to the panelboard to satisfy NEC?
Thanks

If this is a service entrance equipment, you do need to bring the N at least up to the main device to meet the code. There the same conductor will act as EGC as well.
