Electric dryer wiring and power cord connection

Electric dryer wiring and power cord connection

This dryer must be connected correctly before use. The manual requires a qualified electrician to check that your home wiring and fuses are adequate for the appliance.

Before you begin

• The dryer must be connected to a grounded metal, permanent wiring system, or an equipment-grounding conductor must run with the circuit conductors and connect to the appliance grounding terminal or lead.
• The appliance has its own terminal block and must be connected to a separate 240 VAC, 60-Hertz, single-phase circuit fused at 30 amperes.
• The circuit must be fused on both sides of the line.
• Do not connect this appliance to a 110-, 115-, or 120-volt circuit.
• The dryer should be connected to a 4-hole outlet.
• If the plug does not fit the outlet, a proper outlet must be installed by a qualified electrician.
• The power cord connection between the wall receptacle and the appliance terminal block is not supplied with the dryer.
• Do not modify the plug and internal wire provided with the appliance.
• Grounding through the neutral conductor is prohibited for new branch-circuit installations and in any area where local codes prohibit grounding through the neutral conductor.
• The appliance is supplied with the neutral wire grounded. This white ground wire must be moved to the neutral terminal when a 4-wire cord is used, or where grounding through the neutral conductor is prohibited.

Wire size and cord requirements

• If the branch circuit to the appliance is 15 ft. (4.5 m) or less, use UL-listed No.-10 AWG copper wire, or follow local codes.
• If the branch circuit is longer than 15 ft. (4.5 m), use UL-listed No.-8 AWG copper wire, or follow local codes.
• Allow enough slack so the appliance can be moved from its normal location when needed.
• For cord connections, use a 30-amp, 240-volt UL-listed power cord with #10 AWG minimum copper conductor.
• The cord must have closed loop or forked terminals with upturned ends.
• A UL-listed strain relief is required for cord and direct-wire installations.

Important connection rule

Connect each colored wire to the matching color screw on the terminal block. Follow the manual’s wire-to-screw matches exactly.

Four-wire power cord connection

Use this method when your installation requires a 4-wire cord.

1. Remove the terminal block access cover on the upper back of the appliance. 2. Install a UL-listed strain relief into the power cord through-hole. 3. Thread a 30-amp, 240-volt, 4-wire, UL-listed power cord with #10 AWG minimum copper conductor through the strain relief. 4. Transfer the appliance’s ground wire from behind the green ground screw to the center screw of the terminal block. 5. Attach the two hot leads of the power cord, black and red, to the outer terminal block screws. 6. Attach the neutral wire, white, to the center screw of the terminal block. 7. Attach the power cord ground wire to the green ground screw. 8. Tighten all screws securely. 9. Reinstall the terminal block access cover.

Four-wire direct wire connection

Use UL-listed 4-wire #10 AWG minimum copper conductor cable.

1. Remove 5 inches (12.7 cm) of the outer covering from the wire. 2. Remove 5 inches of insulation from the ground wire. 3. Cut off approximately 1.5 inches (3.8 cm) from the other three wires. 4. Strip 1 inch (2.5 cm) of insulation from each of the three wires. 5. Bend the ends of the three shorter wires into a hook shape. 6. Remove the terminal block access cover on the upper back of the appliance. 7. Install a UL-listed strain relief into the power-cord through-hole. 8. Thread the prepared 4-wire cable through the strain relief. 9. Transfer the appliance’s ground wire from behind the green ground screw to the center screw of the terminal block. 10. Attach the two hot leads, black and red, to the outer terminal block screws. 11. Attach the neutral wire, white, to the center screw of the terminal block. 12. Attach the ground wire to the green ground screw. 13. Tighten all screws securely. 14. Reinstall the terminal block access cover.

Three-wire power cord connection

A 3-wire connection is not permitted on new construction after January 1, 1996.

Use a 30-amp, 240-volt, 3-wire, UL-listed power cord with #10 AWG minimum copper conductor and closed loop or forked terminals with upturned ends.

1. Remove the terminal block access cover on the upper back of the appliance. 2. Install a UL-listed strain relief into the power cord through-hole. 3. Thread the 30-amp, 240-volt, 3-wire UL-listed power cord through the strain relief. 4. Attach the two hot leads, black and red, to the outer terminal block screws. 5. Attach the neutral wire, white, to the center terminal block screw. 6. Connect the external ground, if required by local codes, to the green ground screw. 7. Tighten all screws securely. 8. Reinstall the terminal block access cover.

Three-wire direct wire connection

A 3-wire connection is not permitted on new construction after January 1, 1996.

Use UL-listed 3-wire, #10 AWG minimum copper conductor cable. Allow at least 5 ft. (1.5 m) of length so the dryer can be removed and reinstalled.

1. Remove 3.5 inches (8.9 cm) of the outer covering from the wire. 2. Strip 1 inch (2.5 cm) of insulation from each wire. 3. Bend the ends of the three wires into a hook shape. 4. Remove the terminal block access cover on the upper back of the appliance. 5. Install a UL-listed strain relief into the power cord through-hole. 6. Thread the prepared 3-wire cable through the strain relief. 7. Attach the two hot leads, black and red, to the outer terminal block screws. 8. Attach the neutral wire, white, to the center terminal block screw. 9. Connect the external ground, if required by local codes, to the green ground screw. 10. Tighten all screws securely. 11. Reinstall the terminal block access cover.

After wiring

• Make sure all screws are tightened securely.
• Make sure the terminal block access cover is reinstalled.
• If local codes require it, connect the external ground.
• For any installation where the plug does not fit the outlet, have a proper outlet installed by a qualified electrician.

Quick reminders

• Use only the wire sizes and cord types listed in the manual.
• Use copper conductors only.
• Use a UL-listed strain relief.
• Follow local electrical codes as well as the National Electrical Code, ANSI/NFPA 70.
• If you are unsure about your home wiring, have a qualified electrician check it.
