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. If codes permit and a separate ground wire is used, it is recommended that a qualified electrician determine that the ground path is adequate. 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. ■■ Range must be connected to the proper electrical voltage and frequency as specified on the model/serial number rating plate. The model/serial number rating plate is located on the right vertical surface of the oven door frame. Refer to the illustrations in the "Product Dimensions" of the "Location Requirements" section. ■■ This range may be manufactured with a 4-wire power supply cord or may not include a power supply cord. If your range does not include a power supply cord, use a 4-wire power supply cord rated at 250 volts, 40 or 50 amps, and investigated for use with ranges. Range Rating* 120/240 Volts 120/208 Volts Specified Rating of Power Supply Cord Kit and Circuit Protection Amps Range Size If connecting to a 4-wire system: This range is manufactured with the ground connected to the cabinet. 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, 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 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 14-50R 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 conductors sized for the copper 4-wire power cord are: 40-amp circuit 2 No.-8 conductors 1 No.-10 white neutral 1 No.-10 green grounding 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. 8.8-16.5 kW 7.8-12.5 kW 40 or 50** 30" (76.2 cm), 36" (91.4 cm) 16.6-22.5 kW 12.6-18.5 kW 50 48" (121.9 cm) *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. ■ Wire sizes and connections must conform with the rating of the range. ■ The Tech Sheet is located behind the kick plate in a clear plastic bag. 3-wire receptacle (10-50R) 9
