Problems with 220 Volt Electric Dryer Outlets and How to Fix Them


With a problem such as this the dryer circuit should be turned OFF and the dryer should NOT be plugged in until the wiring has been corrected because incorrect wiring of a 220 volt dryer outlet may result in a Electrical Shock Hazard.

How to Evaluate and Correct a Problem with the Dryer Circuit

Inspect and Repair the Circuit Wiring of the Dryer Outlet It is stated in this question that the wire on the dryer started burning next to the box on the electrical outlet, therefore it is essential to determine the cause which resulted in the burnt wire at the outlet. The dryer circuit and wiring components should all be carefully examined to discover the fault, and then repairs should be performed as need. The following information will describe the typical wiring of a dryer circuit and receptacle outlet.

Wiring Connections for a 220 Volt Dryer Outlet

Verify the Wiring Connections to the Dryer Outlet It is very possible that when the dryer receptacle was rewired that the wiring assignments are not correct. The wiring should be corrected using a voltage tester to positively identify each wire of the dryer circuit if the wires are not already clearly marked or indicated. Once the circuit wires have been identified then the connections to the dryer receptacle must be checked to make sure the receptacle is wired correctly.

220 Volt Dryer Circuit
Electric dryers that are 220 volts typically require a dedicated 30 amp circuit containing a 4-wire circuit for new installations, and older homes may have a 3-wire circuit. The 3-wire 240 volt circuit has one ground wire and two power wires, Line 1 and Line 2, of 120 volts each when testing the Line to ground, and 240 volts when tested Line 1 to Line 2. The 4-wire 240 volt circuit is the same as the 3-wire circuit except that it has a separate Neutral wire, which makes this a 4-wire circuit. 4-Wire circuits are required for most new electric dryers, however they may be adapted for use with some older 3-wire dryers.

Wiring a 240 Volt Dryer Receptacle On each of these 30 amp 240 volt dryer receptacle outlets there will be indications for the terminals where the circuit wires are to be located: The Line 1 wire is attached to the terminal with the X designation. The Line 2 wire is attached to the terminal with the Y designation. NOTE: Some brands of 240 volt outlets may specify Line 1 and Line 2. The ground wire is attached to the terminal with the GREEN, Vert or the Ground Symbol The Neutral wire is attached to the terminal designated as White or Blanc.

Ground Fault Protection
Ground Fault protection is required for all receptacle outlets that are installed in a laundry room. This includes 240 volt or 250 volt 30 amp electric clothes dryer receptacle outlets. NOTE: GFCI ground fault protection may be supplied by a GFCI circuit breaker.
