How many watts does an electric oven use?

An electric oven uses 3,600–9,000 watts while running, which is 15–37.5 amps at 240 V.

What size generator runs an electric oven?

An electric oven needs a generator that supplies at least 9,000 running watts. A 10,000 W generator covers it with its running rating alone; add the watts of anything else you run at the same time. The generator must have a 240 V outlet or be connected through a transfer switch or interlock.

What it costs to run an electric oven

Running an electric oven at 6,300 W, the middle of its 3,600–9,000 W range, for one hour a day uses 2,299.5 kWh a year. That costs about $414 a year at $0.18 per kWh, the US average residential price for August 2026.

How it is calculated

  1. kWh per day = 6,300 W × 1 h ÷ 1,000 = 6.3
  2. Per month = 6.3 kWh × 30.4 days × $0.18 = $34

What affects electric oven power use

The bake and broil elements draw the most, and they cycle on and off once the oven reaches temperature. The ranges are the kilowatt ratings at 240 V that GE lists for its wall ovens. GE lists a 20 A circuit for its 27 and 30 inch single wall ovens and 30 or 40 A for double ovens; the breaker comes from the rating plate of your model.

How the amps are calculated

Amps = watts ÷ volts. For 9,000 W at 240 V that is 37.5 A. The 3,600–9,000 W range covers typical models; the nameplate on an electric oven gives the exact figure.
