I have a bathroom which shares a lighting circuit with other living areas. In California this is required to be AFCI protected, but not required to be GFCI protected (receptacles are on a separate dedicated circuit and GFCI protected)
However, with light switches in close proximity to sinks and showers what is considered best practice?
Should I replace my AFCI lighting breaker with a DF breaker offering both protections?
(Square D QO)
The switches and receptacles are grounded. These switches are in a plastic box with a plastic face plate.
