■■ A UL listed conduit connector must be provided at each end of the power supply cable (at the range and at the junction box). ■■ Wire sizes and connections must conform with the rating of the range. ■■ The wiring diagram is located on the Tech Sheet. ■■ The Tech Sheet is located on the back of the range inside a clear plastic bag. If connecting to a 4-wire system: This range is manufactured with the ground connected to the neutral by a link. The ground must be revised so the green ground wire of the 4-wire power supply cord is connected to the cabinet. See the "Electrical Connection - U.S.A. Only" section. Grounding through the neutral conductor is prohibited for new branch-circuit installations (1996 NEC); mobile homes; and recreational vehicles, or an area where local codes prohibit grounding through the neutral conductor. When a 4-wire receptacle of NEMA Type 14-50R is used, a matching UL listed, 4-wire, 250 volt, 40 or 50 amp, range power supply cord (pigtail) must be used. This cord contains 4 copper conductors with ring terminals or open-end spade terminals with upturned ends, terminating in a NEMA Type 14-50P plug on the supply end. The fourth (grounding) conductor must be identified by a green or green/yellow cover and the neutral conductor by a white cover. Cord should be Type SRD or SRDT with a UL listed strain relief and be at least 4 ft (1.22 m) long. 4-wire receptacle (14-50R) The minimum conductor sized for the copper 4-wire power cord are: 40 amp circuit 2 No.-8 conductors 1 No.-10 white neutral 1 No.-8 green grounding If connecting to a 3-wire system: Local codes may permit the use of a UL listed, 3-wire, 250 V, 40 or 50 amp range power supply cord (pigtail). This cord contains 3 copper conductors with ring terminals or open-end spade terminals with upturned ends, terminating in a NEMA Type 10-50P plug on the supply end. Connectors on the appliance end must be provided at the point the power supply cord enters the appliance. This uses a 3-wire receptacle of NEMA Type 10-50R. 3-wire receptacle (10-50R) 6
