Branch circuit or Feeder ?
Branch circuit or Feeder ?
(OP)
Hi,
My understanding from NEC 2011 article 100 is that: branch circuit conductor is connected between panelboard and receptacle, feeder conductor is connected between service equipment and panelboard. Regarding the conductor connected between a panelboard and its subpanel, is it a feeder conductor or a branch circuit conductor? I am asking because feeder and branch circuit have different voltage drop requirements. Thank you in advance.

I thought the total 5% voltage drop fine print note can be any combination between branch and feeder as long as the total voltage drop was no more than 5%.

Be careful when addressing voltage drop. I live in the U.S. and my state's building code mandates that voltage drop not exceed 2% for a feeder and 3% for a branch circuit. Based upon this requirement, a circuit with, for example, 4% voltage drop at the feeder and 1% voltage drop at the branch circuit, would be a violation.

I think the conductor between the panel and its subpanel should be a feeder based on my understanding of NEC and everyone's responses. Thank you all for providing suggestions.
