Equipment Voltage Ratings
Equipment Voltage Ratings
(OP)
Equipment such as switchboards and panel boards have a nameplate voltage rating. Is there an allowable utilization voltage fluctuation above equipment nameplate rating?
Example would be a panel low voltage panel board is rated 208v. If I need to increase voltage on the transformer serving the panel via tap changers to compensate for voltage drop, is there a maximum voltage increase that the panel can see above it's rating? If so, what is the reference document?
Thanks.

In any event, the reference document I would suggest would be ANSI C84.1-2011. You can download a copy for free.
