What size generator to run an electric range/oven?
Electric range/oven sizing at a glance: it draws 3000 running watts.
| Spec | Value |
|---|---|
| Running watts | 3000W |
| Starting (surge) watts | 3000W |
| Recommended class (this load + margin) | 4000W |
Why the startup surge matters
A electric range/oven is a resistive load, so it has no meaningful startup surge. If you size a generator only for the running watts, it can stall the instant the electric range/oven switches on. Always size for the surge.
Sizing the whole system
The number above covers the electric range/oven on its own with a safety margin. In a real outage you'll run other things too — and the right method is your total running load plus the single largest surge among everything, not the sum of every surge.

Common questions
How many watts does an electric range/oven use?
A typical electric range/oven draws about 3000 watts, with no significant startup surge.
What size generator runs an electric range/oven?
For the electric range/oven alone plus a safety margin, a 4000W (≈4.0kW) class generator is appropriate. Add your other essential loads to size the full system.
