Electrical connection

(Not used for Canadian installations)

This range can be connected directly to the fused disconnect (or circuit breaker box) through flexible, armored conduit.

Allow two to three feet of slack in the line so that it can be moved if servicing is ever necessary.

A U.L.-listed cable conduit connector must be provided at each end of the power supply cable (at the range and at the junction box).

Remove the terminal block cover located on the back of range.

Depending on your electrical supply, make the four-wire or three-wire connection to the range following the “Power supply cord method” or “Direct wire method” instructions.

If connecting to a

four-wire electrical system...

This range is manufactured with the ground connected to the cabinet. The ground must be revised so the green grounding wire of the four-wire power supply cord is connected to the cabinet. See “Four-wire electrical connection” section.

When a four-wire receptacle of NEMA Type 14-50R is used, a matching U.L.-listed, four-wire, 250-volt, 40 amp, range power supply cord (pigtail) must be used. This cord contains four copper conductors with ring terminals at the appliance

end, terminated 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 U.L.- listed strain relief and be at least four feet long.

The minimum conductor sizes for the copper four-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

three-wire electrical system...

Local codes may permit the use of a U.L.-listed, 250- volt, 40 amp range power supply cord (pigtail). This cord contains three, No.-10 copper wires and matches a three-wire receptacle of NEMA Type 10-50R. Connectors on the

appliance end must be provided at the point the power supply cord enters the appliance.

WARNING

Electrical Shock Hazard

Disconnect power before servicing.

Electrically ground range.

Failure to follow these instructions can result in death, fire, or electrical shock.

WARNING - Improper connection of the equipment-grounding conductor can result in a risk of electric shock. Check with a qualified electrician or serviceman 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.

1.Disconnect power.

2.Remove the knockout for the 40 amp power supply cord.

3.Assemble a U.L.-listed strain relief in the opening.

4.Insert the power supply cord through the strain relief, allowing enough slack to easily attach the wiring to the terminal block.

5.Use either ring-type terminals or spade terminals with upturned ends to connect the power supply. To secure the power supply cord, use the 3/8" brass nuts attached to the knockout opening. Be sure nuts are installed tight.

6.Complete electrical connection according to your type electrical supply (“Four-wire electrical connection” or “Three-wire electrical connection”).
