Electrical Requirements - U.S.A. Only If codes permit and a separate ground wire is used, it is recommended that a qualified electrical installer determine that the ground path and wire gauge are in accordance with local codes. ■ The Tech Sheet is located on the back of the range inside a clear plastic bag. If connecting to a 4-wire system: Do not use an extension cord. Be sure that the electrical connection and wire size are adequate and in conformance with the National Electrical Code, ANSI/ NFPA 70-latest edition and all local codes and ordinances. A copy of the above code standards can be obtained from: National Fire Protection Association 1 Batterymarch Park Quincy, MA 02169-7471 WARNING: Improper connection of the equipment-grounding conductor can result in a risk of electric shock. Check with a qualified electrician or service technician if you are in doubt as to whether the appliance is properly grounded. Do not modify the power supply cord plug. If it will not fit the outlet, have a proper outlet installed by a qualified electrician. Electrical Connection To properly install your range, you must determine the type of electrical connection you will be using and follow the instructions provided for it here. 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 "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. ■ Range must be connected to the proper electrical voltage and frequency as specified on the model/serial rating plate. The model/serial rating plate is located on the left side frame behind the storage drawer panel or behind the top right side of the oven door. Refer to the figures in "Product Dimensions" in the "Location Requirements" section. 4-wire receptacle (14-50R) ■ This range is manufactured with the neutral terminal connected to the cabinet. Use a 3-wire, UL listed, 40- or 50amp power supply cord (pigtail) (see the following Range Rating chart). If local codes do not permit ground through the neutral, use a 4-wire power supply cord rated at 250 volts, 40 or 50 amps and investigated for use with ranges. 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 Range Rating* Specified Rating of Power Supply Cord Kit and Circuit Protection 120/240 Volts 120/208 Volts Amps 8.8 - 16.5 KW 7.8 - 12.5 KW 40 or 50** 16.6 - 22.5 KW 12.6 - 18.5 KW 50 *The NEC calculated load is less than the total connected load listed on the model/serial rating plate. **If connecting to a 50-amp circuit, use a 50-amp rated cord with kit. For 50-amp rated cord kits, use kits that specify use with a nominal 1³⁄₈" (34.9 mm) diameter connection opening. ■ A circuit breaker is recommended. If connecting to a 3-wire system: Local codes may permit the use of a UL listed, 3-wire, 250-volt, 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. ■ The range can be connected directly to the circuit breaker box (or fused disconnect) through flexible or nonmetallic sheathed, copper or aluminum cable. See the "Electrical Connection - U.S.A. Only" section. 3-wire receptacle (10-50R) ■ Allow 2 to 3 ft (61.0 cm to 91.4 cm) of slack in the line so that the range can be moved if servicing is ever necessary. ■ 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. 5
