Electrical Requirements - U.S.A. Only It is your responsibility: ■■ To contact a qualified electrical installer. ■■ To be sure that the electrical connection is adequate and in conformance with the National Electrical Code, ANSI/ NFPA 70 - latest edition and all local codes and ordinances. The National Electrical Code requires a 4-wire power supply connection for homes built after 1996, dryer circuits involved in remodeling after 1996, and all mobile home installations. A copy of the above code standards can be obtained from: National Fire Protection Association, One Batterymarch Park, Quincy, MA 02269. ■■ To supply the required 3- or 4-wire, single-phase, 120/240 volt, 60 Hz, AC only electrical supply (or 3- or 4-wire, 120/208 volt electrical supply, if specified on the serial/rating plate) on a separate 30 amp circuit, fused on both sides of the line. Connect to an individual branch circuit. Do not have a fuse in the neutral or grounding circuit. ■■ Do not use an extension cord. ■■ If codes permit and a separate ground wire is used, it is recommended that a qualified electrician determine that the ground path is adequate. Electrical Connection To properly install your washer/dryer, you must determine the type of electrical connection you will be using and follow the instructions provided for it here. ■■ This washer/dryer is manufactured ready to install with a 3-wire electrical supply connection. A neutral ground conductor (white wire) is provided between the power supply neutral connection (center terminal) and the washer/dryer external grounding point (green screw). If the washer/dryer is installed with a 4-wire electrical supply connection, one end of the neutral ground conductor must be removed from the external ground connector (green screw), and secured under the neutral terminal (center screw) of the terminal block. When both ends of the neutral ground conductor are secured under the neutral terminal (center or white wire) of the terminal block, the washer/dryer cabinet is isolated from the neutral conductor. The green ground wire of the 4-wire power cord must be secured to the washer/dryer cabinet with the green ground screw. ■■ If local codes do not permit the connection of a neutral ground wire to the neutral wire, see "Optional External Ground 3-wire connection." ■■ A 4-wire power supply connection must be used when the appliance is installed in a location where grounding through the neutral conductor is prohibited. Grounding through the neutral is prohibited for (1) new branch-circuit installations after 1996, (2) mobile homes, (3) recreational vehicles, and (4) areas where local codes prohibit grounding through the neutral conductors. Power supply cord Use a UL Listed power supply cord kit marked for use with clothes dryers. The kit should contain: ■■ A UL Listed 30 amp power supply cord, rated 120/240 volt minimum. The cord should be type SRD or SRDT and be at least 5 ft. (1.5 m) long. The wires that connect to the washer/dryer must end in ring terminals or spade terminals with upturned ends. If your outlet looks like this: 4-wire receptacle (14-30R) Then choose a 4-wire power supply cord with ring or spade terminals and UL Listed strain relief. The 4-wire power supply cord, at least 5 ft. (1.5 m) long, must have four 10-gauge copper wires and match a 4-wire receptacle of NEMA-Type 14-30R. The ground wire (ground conductor) may be either green or bare. The neutral conductor must be identified by a white cover. 3-wire receptacle (10-30R) Then choose a 3-wire power supply cord with ring or spade terminals and UL Listed strain relief. The 3-wire power supply cord, at least 5 ft. (1.5 m) long, must have three 10-gauge copper wires and match a 3-wire receptacle of NEMA-Type 10-30R. 24
