volt drop calc

[Farmelectrics]

just a quickie volt drop = mv x amps x length divided by 1000 so the amps is that the breaker size or the current carrying capacity of the conductor

I'd say, Design Current, or for max volt drop, breaker size.

Just looked in BRB section 6 page 312, it says to use the design current.
Can also correct for temp & power factor.
