Microwave Drawer Power Requirements at a Glance#
A microwave drawer runs on 120 volts and pulls the familiar oversized-microwave draw — 11 to 13 amps, around 1,450 to 1,550 watts — so it wants a dedicated 20-amp branch and a 5-15R or 5-20R outlet in the cabinet. That the box hides below the counter does not lighten the load. The table above splits the 24 and 30-inch models.
Microwave Drawer Electrical Specifications#
| Configuration | Voltage | Amps | Watts (max load) | Breaker | Outlet (NEMA) |
|---|---|---|---|---|---|
| 24-inch microwave drawer | 120 V | 11–12 A | 1,450 W | 20 A | 5-15R |
| 30-inch microwave drawer | 120 V | 12–13 A | 1,550 W | 20 A | 5-15R / 5-20R |
A drawer microwave slides open at waist height instead of swinging a door, which lets a designer bury it in an island or under the counter far from the range, and that placement is exactly why it earns a home-run branch back to the panel. The pull is the familiar oversized-microwave draw, so the circuit matches a countertop unit even though the box hides below the worktop.

Circuit and Breaker Sizing for the Microwave Drawer#
A microwave's magnetron is a heavy, steady load, and the drawer format is no exception. At 11 to 13 amps it needs a 20-amp branch wired in 12-gauge copper — a 15-amp circuit would run too close to its limit for a continuously cooking appliance. Because a microwave drawer is usually buried in an island or a base cabinet far from the range, it earns a home-run branch back to the panel rather than sharing a kitchen counter circuit. The 30-inch model draws a touch more than the 24-inch, but both land on the same 20-amp feed.
Installation and Safety Notes for Microwave Drawer Wiring#
Placement is the whole reason this appliance wants its own line: set into an island or under the counter, it plugs into a grounded 5-15R or 5-20R receptacle inside the cabinet, fed by a dedicated 20-amp branch. Running that home-run circuit into an island — often meaning wire through the floor — is permit-and-inspection work and a job for a licensed electrician, since island feeds have their own code requirements. Confirm the dedicated 20-amp branch and the cabinet outlet before the island is closed up, because retrofitting a feed afterward is far harder.
