Over the range microwave electrical issue

Hello All,

New to site. Currently attempting to install over the range microwave. The house is 30 years old and there is no electrical outlet in the cabinet over the stove. Nearest outlet is aprox 36" from top of microwave. Can an additional outlet be installed off the exsisting circut or would it be better to replace cord on microwave with longer cord if possible? An.y help would be appreciated

Best practice is to run a new circuit from the panel to the cabinet above the microwave.

What with fans and lights most of the over stove microwaves often draw more then 10 amps or in excess of 50% of a 20 amp circuit. 2008 NEC code 210.23 states:
(2) Utilization Equipment Fastened in Place. The total rating of utilization equipment fastened in place, other than luminaires, shall not exceed 50 percent of the branch circuit ampere rating where lighting units, cord-and-plugconnected
utilization equipment not fastened in place, or
both, are also supplied.
So by code you probably would need a new dedicated 20a circuit. The manufacturer may also require it.

Your instructions are going to call for a new dedicated circuit.
