Electrical Circuit Requirements for an Electric Dryer
Understanding the electric circuit requirements for an electric dryer.
- James, you should not wire a NEMA 14-20P Dryer Cord into a 20 amp outlet because of the following:
- The dryer and the cord are rated for 30 amps which will overload the 20 amp outlet.
- The 20 amp circuit wiring you are describing is not the right size for a 240 volt electric dryer.
- Electric Circuit for a Dryer
The NEMA 14-30P Dryer Cord and dryer outlet will require a dedicated 4-wire 30 amp 240 volt circuit to be installed.
