Hello all Are Arc fault circuit interrupters required for individual branch circuits such as the dishwasher,garbage disposal,refrigerator,microwave,range hood,forced air unit,A/C unit,and garage door opener? I'm familiar with a bit of the code which states some thing to the effect "in all habitable rooms" including dining rooms,living rooms closets etc.But I can find nothing which details these particular circuits.Also is a electric dryer circuit a mandatory requirement or an optional item? I made the mistake of purchasing a rather small 200 amp service panel together with several combination AFCI's. Sincere thanks Mark
