Dedicated circuit for range hood

[Dennis Alwon]

Pierre, I don't see where that requires a dedicated circuit for a range hood.

I agree the code only says the range hood must be on an individual circuit if it is wired with cord and plug (why I don't know).

Many homes are constructed with a simple hardwired hood on a 15A lighting circuit, then the MW is added later on the same ckt.

Don't get me wrong because I always wire the range hood on its own 20 amp circuit for that exact reason, however many homes do have the microwave already installed in a dedicated space. So, your proposal would have to give exception to a kitchen that has a dedicated space for the microwave??? For that matter perhaps every receptacle in the kitchen should be on its own circuit because many families just use counter top microwaves. We never know where they may plug them in. My point is that we can't mandate for every situation or we would all be going nuts and the cost of a house becomes absurd.

Can anyone come up with any other single piece of equipment that the NEC requires to be served by an individual branch circuit?

I can only come up with electrical furnaces, electrode-type boilers, some elevator stuff and perhaps a sign outlet. Otherwise, I don't think the code identifies any one appliance or equipment requiring a individual or "dedicated" branch circuit.

Those are not individual branch circuits. See the definition in Article 100.

There can be several different loads plugged into the Laundry circuit, it's not specific to any equipment in particular.
