Electric Oven / Range Wattage for Generator Sizing
About the Electric Oven / Range
A full-size electric oven or range with multiple burners and an oven cavity. Electric ovens use resistive heating elements and draw substantial power but have no motor-driven starting surge. The actual draw depends on how many burners are active and the oven temperature setting. A single burner on high might draw 1200-2500 watts, while the oven element alone can draw 2000-5000 watts. If you plan to cook full meals during extended outages, an electric oven is one of the largest loads to account for in generator sizing.
Generator Sizing for a Electric Oven / Range
Running a electric oven / range by itself requires a generator with at least 3,125 W of capacity (4 kW), which includes a 25% safety margin. However, you rarely run a single appliance on a generator. When combined with other appliances, the electric oven / range contributes 2,500 W to the continuous running load.
The electric oven / range is a resistive load, meaning it uses a heating element or simple electronic circuit rather than a motor. Resistive loads draw the same wattage from the moment they turn on until they turn off, with no starting surge. This makes them the easiest type of appliance to run on a generator. When calculating your total generator load, the electric oven / range adds a flat 2,500 W to your running total with no impact on peak surge calculations. Resistive loads also produce a power factor of 1.0, meaning they use electricity very efficiently with no wasted reactive power.
To determine the total generator size you need, use our interactive calculator to combine the electric oven / range with your other appliances. The calculator automatically handles the starting surge calculation and applies the 25% safety margin to give you an accurate recommendation.

Tips for Running a Electric Oven / Range on a Generator
Running a electric oven / range on a generator is straightforward since it is a purely resistive load. There are no special starting procedures or surge considerations. Simply ensure your generator's continuous (rated) wattage exceeds 2,500 W plus the wattage of all other appliances running simultaneously.
Since the electric oven / range draws a constant 2,500 W whenever it is operating, you can accurately predict generator fuel consumption. At typical generator fuel efficiencies, running the electric oven / range continuously adds approximately 0.3 gallons of gasoline per hour to your fuel consumption. If the electric oven / range operates intermittently (like a thermostat-controlled heater), the actual fuel impact will be lower.
For sensitive electronic components within the electric oven / range, an inverter generator provides the cleanest power output. However, most resistive appliances work fine on conventional generators as well. If you are running the electric oven / range along with sensitive electronics like computers, the inverter generator protects all connected devices.

Frequently Asked Questions
How many watts does a electric oven / range use?
A electric oven / range uses approximately 2500 watts of continuous (running) power during normal operation. As a resistive load with no motor, it has no starting surge above its running wattage.
What size generator do I need to run a electric oven / range?
To run a electric oven / range by itself, you need a generator rated for at least 3,125 W (4 kW), which includes a 25% safety margin above the running wattage of 2500W. However, most people run additional appliances alongside the electric oven / range, so your actual generator needs will be higher. Use our calculator to add your other appliances and get a comprehensive recommendation.
Can I run a electric oven / range on an inverter generator?
Yes, a electric oven / range runs perfectly well on an inverter generator. As a resistive load with no motor starting surge, it is one of the easiest appliances to power with any generator type. The clean sine wave output of an inverter generator is a bonus for any electronic components.
