How many watts does an electric dryer use
While it runs, an electric dryer draws 4,000 to 6,000 W, and it has no starting surge. The smallest portable that can run it is rated 7,500 W.
Watts for running and starting
| Load | Running | Starting |
|---|---|---|
| Electric dryer | 4,000 to 6,000 W | no surge |
The Champion wattage chart, 04-17-26, is the source. Your electric dryer's nameplate lists its exact figure in watts, or you can find it in amps. Multiply the amps by 120 V. Use 240 V only when the load, for example a well pump, runs on a two-pole breaker.
Smallest generator able to start it
Any generator you use must handle 6,000 W while staying at 80% of its rating or less. The smallest common portable that meets both conditions is 7,500 W. Any other load you add takes its running watts from that same generator.
Electric dryer alongside other loads
| Electric dryer plus | Running | Peak at a start | Smallest portable |
|---|---|---|---|
| lights, TV and the router | 6,570 W | 6,570 W | 10,000 W |
| a freezer and lights | 6,650 W | 7,150 W | 10,000 W |
| a 1/2 hp sump pump and lights | 7,200 W | 8,300 W | 10,000 W |
| a microwave | 7,200 W | 7,200 W | 10,000 W |
| a 1 hp well pump | 8,000 W | 10,000 W | 10,000 W |
| a window AC, 10,000 BTU | 7,200 W | 8,400 W | 10,000 W |
Running watts add up, but only the largest motor start sits on top of the total. Starting output on a portable runs about 25% above its running rating. All loads appear in the appliance wattage chart.
