what size breaker for dryer

For a typical electric dryer , the standard breaker is a 30-amp double- pole breaker on a 240-volt circuit, with 10-gauge copper wire. Dryers that are smaller, gas-powered, or specifically labeled for different electrical needs can use a different size, so the dryer's nameplate or manual is the final word.

Usual sizing

• Most residential electric dryers: 30 amps.
• Typical wire pairing: 10 AWG copper.
• Larger or commercial units may need a different breaker size based on the appliance label.

Safety note

A breaker that is too small can trip during normal use, while one that is too large can leave the wiring unprotected. The safest choice is to match the dryer’s listed amperage and follow local electrical code requirements.

Practical rule

If you are replacing a breaker for a standard home electric dryer, the most common answer is 30 amps. If the dryer is gas, compact, or a nonstandard model, the breaker may be 15 or 20 amps instead.
