Generally, a single receptacle is installed in the cabinet above the range for the microwave. Here's why: Dedicated Circuit

Microwaves typically require a dedicated 15- or 20-amp circuit. It's best practice to have a single receptacle on that circuit to avoid the possibility of overloading the circuit by plugging in other appliances.

Code Compliance

Local electrical codes may specify a single receptacle for this type of installation.*

Safety: A single receptacle is a safer option since the microwave is the only appliance that should be plugged into it.While it's possible to install a duplex receptacle, it's not ideal and could potentially lead to issues. Flag for review
