I'm having some trouble with an exam prep question and I'm hoping someone can clarify for me. It's a voltage drop question regarding finding the max load allowable on a conductor so as to not exceed the NEC recommendations for voltage drop. My question is do I calculate at 2%, or 3%. These seem like they are feeders to me, so wouldn't a 2% calculation apply?
1/0 AWG copper conductors in a nonmetallic raceway to a panelboard located 200 ft. from a 240V, single phase power source. What's the maximum load that can placed on the panelboard without exceeding the NEC recommendation for voltage drop?
I wasn't sure, so I worked out for 2% & 3%, both answers possible options on the test.
