A:Answer That will depend on when your building was built and on what your local codes and ordinances are. The wiring and grounding of the LG 4.2 Cu. Ft. 14-Cycle Compact Electric Dryer, Model # DLEC888W must conform to the latest edition of the National Electrical Code, ANSI/NFPA 70 and all applicable local regulations. It has its own terminal block that 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.) The power cord (pigtail) connection between wall receptacle and dryer terminal block IS NOT supplied with dryer. Type of pigtail and gauge of wire must conform to local code or in their absence, to the latest edition of the National Electrical Code, ANSI/NFPA 70. A 4-wire connection is required for all mobile and manufactured home installations, as well as all new construction after January 1, 1996. A 4-wire connection must be used where local codes do not permit grounding through the neutral wire. lf your local codes or ordinances do not allow the use of a 3 wire connection, or you are installing your dryer in a mobile home, you must use a 4-wire connection. If your home has a 4-wire receptacle (NEMA type 14-30R) you will be using a UL listed, 120/240 volt minimum, 30amp, dryer power supply cord. If your home has a 3-wire receptacle (NEMA type 10-30R), you will be using a a UL listed, 120/240 volt minimum, 30amp, dryer power supply cord...^IFV
