Electrical Connections

Important Safety Instructions

  • Be sure the cooktop is installed and grounded properly by a qualified installer or service technician.

  • This cooktop must be electrically grounded in accordance with local codes or, in their absence, with the National Electrical Code ANSI/NFPA No. 70, latest edition in the United States.

Warning

  • The electrical power to the cooktop must be shut off while line connections are being made. Failure to do so could result in serious injury or death.

Providing the Electrical Connection

  • Install the junction box under the cabinet and run 120/240 or 120/208 Volt, AC wire from the main circuit panel.

Note

  • DO NOT connect the wire to the circuit panel at this time.

Electrical Requirements

Observe all governing codes and local ordinances

  • A 3-wire or 4-wire single-phase 120/240 or 120/208 Volt, 60 Hz AC-only electrical supply is required on a separate circuit fused on both sides of the line (time-delay fuse or circuit breaker is recommended). DO NOT fuse neutral. The fuse size must not exceed the circuit rating of the appliance specified on the nameplate.

    • 30" Radiant cooktop can consume up to 7700 W at 240 VAC. A circuit breaker rated with #8 AWG for 40 Amp continuous load must be used.

    • 36" Radiant cooktop can consume up to 10500 W at 240 VAC. A circuit breaker rated with #8 AWG for 50 Amp continuous load must be used.

    Warning

    • Do not use an extension cord with this appliance. Doing so may result in a fire, electrical shock, or other personal injury.

    Note

    • Wire sizes and connections must conform to the fuse size and rating of the appliance in accordance with the National Electrical Code ANSI/NFPA No. 70, latest edition, and local codes and ordinances.

  • The appliance should be connected to the fused disconnect (or circuit breaker) box through flexible armored or nonmetallic sheathed cable. The flexible armored cable extending from this appliance should be connected directly to the grounded junction box. The junction box should be located as shown in Dimensions and Clearances with as much slack as possible remaining in the cable between the box and the appliance, so it can be moved if servicing is ever necessary.

  • A suitable strain relief must be provided to attach the flexible armored cable to the junction box.

Electrical Connection

Connect the flexible armored cable that extends from the surface unit to the junction box using a suitable strain relief at the point the armored cable enters the junction box. Then make the electrical connection as follows.

Electrical ground is required on this appliance.

This appliance is manufactured with a supply wire and a frame-connected green or bare copper grounding wire.

Note

TO ELECTRICIAN:

  • The armored cable leads supplied with the appliance are UL-listed for connection to larger gauge household wiring. The insulation of the leads is rated at temperatures much higher than the temperature rating of household wiring. The current-carrying capacity of the conductor wire is governed by the temperature rating of the insulation around the wire, rather than the wire gauge alone.

Warning

  • DO NOT ground to a gas supply pipe. DO NOT connect to electrical power supply until appliance is permanently grounded. Connect the ground wire before turning on the power.

  • This appliance is equipped with a copper conductor flexible cable. If connection is made to aluminum house wiring, use only special connectors which are approved for joining copper and aluminum wires in accordance with the National Electrical Code and local codes and ordinances. Improper connection of aluminum house wiring to copper leads can result in a short circuit or fire. Follow the connector manufacturer’s recommended procedure closely.

Where Local Codes Permit Connecting the Appliance-Grounding Conductor to the Neutral (White) Wire

Observe all governing codes and local ordinances.

  • Disconnect the power supply.

  • At the circuit breaker box, fuse box or junction box, connect appliance and power supply cable wires as shown.

Warning

  • You may not ground the cooktop through the neutral (white) wire if cooktop is used in a new branch circuit installation (1996 NEC), mobile home, recreational vehicle, or where local codes do not permit grounding to the neutral (white) wire. When grounding to the neutral (white) wire is prohibited, you must use a 4-wire power supply cable. Failure to heed this warning may result in electrocution or other serious personal injury.
