What Size Wire for Electric Dryer?: Complete Wiring Guide
A Electric Dryer requires 10 AWG copper with a 30A double-pole on a 240V dedicated circuit. Here is the complete NEC-compliant wiring guide.
Electric Dryer Wiring Details
Electric dryers typically draw 22-24 amps at 240V (5,000-5,800W). NEC 220.54 requires a dedicated 30A circuit with 10 AWG copper conductors. Use 10/3 NM-B cable (3 conductors + ground) for new installations. The third conductor provides the neutral needed for the 120V motor and controls. Modern dryers require a NEMA 14-30 receptacle (4-prong), the older NEMA 10-30 (3-prong) is not permitted for new installations per NEC 250.140 because it lacks a separate equipment ground.
NEC Code Reference
The wiring requirements for a Electric Dryer are governed by NEC 220.54. Always check the appliance nameplate for specific electrical requirements, the manufacturer's specifications take precedence over general guidelines. Your local AHJ (Authority Having Jurisdiction) may have additional requirements beyond the NEC.
Pro Tip
Running a gas dryer instead? A gas dryer only needs a standard 120V, 15A outlet for the motor and controls. The energy cost difference is significant: an electric dryer costs $50-80/month for a family of four, while a gas dryer costs $15-25/month in gas plus $3-5/month in electricity.
