What ampacity is specified for the branch circuit serving laundry receptacles?

• A. 15 amp
• B. 20 amp
• C. 25 amp
• D. 30 amp

Answer: (B)

The main idea is that laundry receptacles in a dwelling must be fed by a 20-amp branch circuit. This sizing accounts for the practical laundry loads (like a washer) that can pull more than 15 A, and it helps prevent nuisance tripping while meeting code requirements. A 20-amp circuit provides the appropriate capacity for laundry outlets, whereas 15 A wouldn’t offer enough headroom, and 25 A or 30 A are not standard ratings for this use (30 A is typically reserved for larger appliances like dryers or ranges).
