afci and shared circuit

[mannyb]

I have few questions I dont want to post 3 separate post. We are doing this kithcen and dining room remodel.

1. do we need to afci the refridge in kitchen? my boss says its exempt if the receptacle is behind the rrefridge. I dont see any excemptions in code
2. can i use 20a circuit for disposal and dishwasher ? i only see 210.23 a 1 and or 2, Im not sure, we already separated dishwasher and disposal Im just checking if I could have.

I don't see any exemptions for a refrigerator. As far as the dishwasher and disposal I would put them on their own circuits but Code wise I don't consider them continuous loads so if they add up to less than 20A I guess you could. I don't find anything that says you can't.

1. The exemption your boss was referring to was for GFCIs in basement and garages, that exception was deleted several codes ago

My State exempts refrigerators from AFCI. No GFCI either if its not within 6' of the sink.

The NEC itself doesn't directly require a dishwasher to be on its own circuit.

Very often the dishwasher install instructions will call for a separate circuit. Following the install instructions is an NEC requirement.

FWIW (DIY report) in my own kitchen I ran two circuits under the sink. One for the dishwasher. The other shared between the disposal and an instant hot water tap. Very likely they would all be fine on a single circuit.
