National Electrical Installation Standards

Standards as High as Your Own

Tuesday, January 2, 2018


Good morning. My question is regarding a "single "receptacle on an "individual "branch circuit. If I infer this particular section correctly, it allows the installer to use an ampere rating not LESS than the actual branch circuit used. So if I have a 15 amp circuit and am using a 30 amp 240 Volt receptacle (L6)it's code compliant. It feeds a PDU with a L6P(6 amps per leg).Keep in mind this is an individual branch circuit with a single receptacle NOT two or more receptacles. The inspector is saying it must be a 30 amp circuit even on an individual circuit. Am I wrong?

Your thoughts, Edward LoGatto



Hey Edward thanks for your question. If I understand your example you are correct. A single receptacle must have an ampere rating at least equal to that of the branch circuit as stated in 210.21(B)(1). Using a higher rated receptacle is not prohibited. See the definitions of Branch Circuit, Individual and Receptacle in Article 100. Make sure you are complying with any instructions included with the equipment if it is listed as stated in 110.3(B).
