Taking into account that the NEC directly addresses voltage drop as a non-enforceable FPN, I've been asked for my opinion on a situation.
Without given a specific load or specific wire size, if a job (industrial) calls for a circuit to feed 120v receptacles at various locations is there any "accepted standard" where a certain maximum voltage drop would be mandated ?
Specifically a plant asked for a 20 amp circuit with convenience outlets at various locations and are now concerned that with a 12 amp load the voltage drop is excessive for items being plugged in.
If the job consisted of ONE duplex as opposed to multiple outlets, would that make a difference ?
My opinion is that, without specifying a load, the calculated load of 180va would be all that would be applicable to the E/C.
