NEC Microwave Dedicated Circuit

Question

Question about microwaves and dedicated circuits.  What's the difference in circuit requirements (amps? dedication? something else?) between microwaves in these locations:

mounted under a cabinet over the range
sitting on a countertop
mounted under a cabinet (but not OTR)
mounted under the countertop (drawer-style)
sitting on a shelf somewhere above the counter
sitting on a shelf somewhere below the counter?

NoSparksPlease · Answer

The code doesn't address microwaves as a specific appliance, but NEC 210.23(A)(2) Utilization Equipment Fastened in Place limits equipment to 50% of a circuit when shared with lighting or other equipment not fastened in place.
So if it's fastened in place, which would likely place it on a designated kitchen circuit, a shared kitchen circuit would have to be 20A, so a microwave would not be able to exceed 1200W without requiring a dedicated circuit.
