Bathroom branch circuit requirements have changed for the 2020 Code cycle. The one 20-amp branch circuit traditionally required by NEC Section 210.11(C)(3) to feed only receptacles in dwelling unit bathroom(s) is now restricted to feeding only countertop receptacles in those same bathroom(s).
The receptacles permitted on this newly defined branch circuit include any countertop receptacles required to be within 3 feet of the bathroom’s sink basin and any other receptacle(s) installed to serve countertops or similar work surfaces in these bathroom(s).
