How Many Amps Does an Electric Oven Use?

Electric Oven amperage at 120 V and 240 V

Same 3,000 W load: the current halves when the voltage doubles. Electric Oven is typically a 240 V appliance in US homes.

Breaker and circuit for an electric oven

Electric Oven runs on its own dedicated 240 V circuit: plan on a 40-50 A double-pole breaker (50 A with 6 AWG copper is the US standard). Ranges are sized from nameplate demand per NEC Table 220.55, with a 40 A minimum branch circuit (210.19). The 3,000 W running figure here is one element, not the whole connected load.

Guidance only: actual circuit sizing depends on your unit's nameplate, wire run length, and local code. Confirm with a licensed electrician. See the wire & breaker size chart for the full NEC ampacity table.

Measure what an electric oven actually draws

The figures above are typical ratings, and this load is usually hardwired or on a 240 V circuit, so a plug-in meter can't reach it. A clamp meter reads the current on one conductor at the disconnect or panel without breaking the circuit; opening a panel is work for someone qualified, and the voltage pen confirms a circuit is dead first.
