Generator size for an electric dryer
These use typical wattages (running and starting), plus 20% headroom on the running load. Your appliance's label is the best guide.
| What you run | Running | Peak at startup | Generator to shop for |
|---|---|---|---|
| Electric dryer alone | 5,400 W | 6,750 W | 6,500 running watts |
| + refrigerator, lights, laptop and router | 6,350 W | 7,850 W | 9,000 running watts |
| + the essentials (fridge, sump pump, furnace blower, lights, laptop) | 7,950 W | 9,500 W | 11,000 running watts |
Motors need a surge when they start, which is why the starting watts are higher than the running watts. Build your list in the generator size calculator, and see the generator sizing guide for safety (never run a generator indoors) and how to connect it properly.
