A bathroom is required to have a dedicated circuit of what amperage rating?

• A. 20A
• B. 15A
• C. 30A
• D. 50A

Answer: (A)

A bathroom receptacle circuit must be on a dedicated 20-ampere branch circuit. This setup provides enough headroom for high-draw bathroom devices like hair dryers and curling irons and helps prevent nuisance trips, while keeping bathroom loads isolated from other parts of the system. While receptacles on a 20A circuit can be 15A devices, the important part is that the circuit feeding them is rated at 20A. A 15A circuit would be more prone to tripping with those appliances, and 30A or 50A circuits are not appropriate for typical bathroom receptacle outlets. So the required dedicated circuit rating is 20 amperes.
