Giải thích
A dedicated 20-ampere branch circuit is required for bathroom receptacle outlets, and it may serve only bathroom receptacles unless it supplies a single bathroom entirely. A 15-ampere circuit is not permitted for this purpose, and 25 or 30 amperes are not used for 125-volt, 15- and 20-ampere receptacle circuits.
