No gfi and no dedicated circuit, BUT if this were a Range Hood that was cord & plug, then it must be a individual branch circuit.

...Other than the code says so, any good reason you can think of for that requirement?

Be careful on this one because the manufacturers instructions for a range hood microwave may very well tell you it needs a separate circuit. FYI, I always put them on dedicated circuits but not GFCI protected.

05 NEC 422.16(B)(4)(5) requires receptacle to be supplied by an individual branch circuit. I might add that Table 210.21(B)(2) states you can only load up a 15 amp receptacle to 12 amps. So if the microhood is rated at 1440w or more it should be a 20 amp circuit with a single 20 amp receptacle. No GFCI protection required.

Can you explain for me the single recep part. Assumming you mean one contact point, as in not a duplex.

It does not have to be on a single recep. If you use a single recep. on an individual branch circuit then the recep. must not be rated less than the circuit. art. 210.21(B)(1)

In the 05 handbook the explanation for the definition Individual Branch Circuit states "An individual branch circuit supplies only one single receptacle for the connection of a single attachment plug" I am not sure where one would find this elsewhere in the NEC.

Other than a "What If Scenario", No.
It basically provides future upgrading to a combination microwave oven and range hood, which IMO, the NEC has no right to enforce. :smile:
