Gas Cooktop Power Requirements at a Glance#
A gas cooktop cooks with gas, so it needs household power only for its spark igniters and controls: 120 volts at just 1 to 2 amps, around 100 to 240 watts, on a standard 15-amp circuit and an ordinary 5-15R outlet. The real hookup is the gas line, not the wiring. The table above lists the tiny electrical demand.
Gas Cooktop Electrical Specifications#
| Configuration | Voltage | Amps | Watts (max load) | Breaker | Outlet (NEMA) |
|---|---|---|---|---|---|
| Drop-in gas cooktop with electronic ignition | 120 V | 1–2 A | 100–240 W | 15 A | 5-15R |
A gas cooktop drops into the counter with only its sealed burners and a spark igniter, so it leans on household current for nothing more than lighting the flame and running the control knobs. That tiny draw means the cooktop reaches a standard receptacle in the cabinet below, while the real hookup work is the gas line, shutoff and flexible connector feeding the burners.

Circuit and Breaker Sizing for the Gas Cooktop#
There is almost nothing to size here. At 1 to 2 amps the cooktop's electronics barely load a 15-amp branch wired in standard 14-gauge copper, so it reaches whatever convenience outlet sits in the cabinet below — no dedicated circuit, no heavy gauge, no 240-volt feed. The breaker matters only in that a standard 15-amp branch is more than enough; the electrical side of a gas cooktop is genuinely an afterthought next to the gas connection.
Gas Line and 120-Volt Power for the Gas Cooktop#
Even though it burns gas, a gas cooktop still needs that standard 120-volt circuit alive: the spark igniters that light the burners and the control knobs' electronics run on it, drawing the 1-to-2-amp trickle in the table above. Alongside the outlet, the burners are fed by the gas line, its shutoff, and a flexible connector reaching the cutout — that plumbing is the substantial part of the install. Note that during a power outage the electronic igniters will not spark, though the gas itself still flows for a manual light.

Installation and Safety Notes for Gas Cooktop Wiring#
Matching the cord to the receptacle is trivial — a standard three-prong cord into a grounded 5-15R outlet in the cabinet below. The attention goes to the gas side: the shutoff valve, the flexible connector, and a leak test all belong to the gas fitting, which is where permits and inspection apply. Because a gas connection carries a real safety stake, the gas hookup is a licensed pro's job even when the electrical plug is something a homeowner could manage. Confirm the outlet is grounded and the gas line is leak-tested before first use.
