in 210.12b it states that bathroom and kitchen don't have to be arc faulted , but what about the lighting in bought the are not gfci so would they have to be arc faulted
Actually, 210.12(B) says the
outlets in the areas listed
have to be arc faulted. . . it's a positive statement.
"Lighting" is a form of an
outlet, that is, a
lighting outlet. Since lighting in a bath or a kitchen are not in the list of areas in 210.12(B), they are not
required to have arc fault protection.
You can add it if you wish. It's just not required.
