How to Splice and Extend an Electric Dryer Circuit

The following is an example of the process to extend a dryer circuit by using the existing outlet box as a junction box to extend the circuit wiring to a new location.

  1. Turn Off the Electrical Power for the Dryer Circuit
    Identify the existing dryer circuit at the panel supplying the power and turn it off.
    Place a notice or tag at the panel to indicate that work is being done on the circuit.
    Use a voltage tester at the dryer outlet to ensure that the circuit power has been turned off.
  2. Locate and Install the New Dryer Outlet Box
    Determine the desired location for the new dryer outlet to be used for the new stackable dryer unit.
    Consult the installation manual for detailed information about the new dryer outlet and cord. Attention should be given to the new dryer and the position and length of the cord to be sure the new outlet is located properly and is accessible when the new dryer is installed.
  3. Install the New Length of Dryer Circuit Cable
    The new dryer circuit cable should be exactly the same as the existing dryer cable, being sure that the wire type and wire gauge matches the existing circuit wires.
    Install the additional length of dryer cable from the new dryer outlet to the existing dryer outlet.
    Protect and secure the new circuit cable and wiring according to the project application.
