Branch Circuits & WiringQuestion 149 of 521
A single receptacle installed on an individual branch circuit must have an ampere rating not less than what value relative to the branch circuit?
a.50 percent of the circuit
b.The rating of the branch circuit
c.125 percent of the circuit
d.No minimum applies
Explanation
Section 210.21(B)(1) requires a single receptacle on an individual branch circuit to have an ampere rating not less than that of the branch circuit. A 20-A individual circuit therefore needs at least a 20-A receptacle. Half the circuit rating and 'no minimum' are wrong, and 125 percent is not required for the receptacle.
