You will install an outlet in the cabinet above the microhood on a dedicated breaker. You will run a 15 or 20 amp cable from the location to the panel and install a new single pole breaker.

Why not? We only need to supply a 'Laundry Circuit' no where is it stated that it is for the washing machine.... with that said, if the loads met the circuit criteria I don't see any violation.

I disagree, a microwave range hood is not what 422.16 (4) is referring to, nor was intended to.

Stickboy,

The laundry circuit is restricted to the laundry area only.

(2) Laundry Branch Circuits. In addition to the number
of branch circuits required by other parts of this section, at
least one additional 20-ampere branch circuit shall be provided
to supply the laundry receptacle outlet(s) required by
210.52(F). This circuit shall have no other outlets.

How would you get around the 422.16(4) requirement? The instructions for the MWH would also call for a dedicated circuit.

Why not add it to the D/W and disposal circuit?

Jim, you cannot assume the washer is utilizing the required laundry branch circuit. This was my point to begin with when someone said is was a code violation to have anything else on the washing machine circuit.

422.16(4) does not include microwave hoods, only range hoods, there is a difference, and this is why 422.16(4) exists to begin with, also, you cannot assume a microwave hood will call for a dedicated circuit.


With that said, im all for a dedicated circuit, but it seems sheepish for the nec to require such nonsense, since I can buy a standard microwave and place it on my counter and plug it in to any small appliance circuit shared with other appliances...
