  ELECTRICAL REQUIREMENTS

WARNING:

This appliance must be properly grounded.

WARNING:

 To prevent fire or shock, do not use an extension cord with this appliance.

WARNING:

 To prevent shock, remove house fuse or open circuit breaker before 

beginning installation.

WARNING:

 Improper connection of aluminum house wiring to copper leads can result 

in an electrical hazard or fire. Use only connectors designed for joining copper to aluminum and follow the 

manufacturer’s recommended procedure closely.
We recommend you have the electrical wiring and hookup of your appliance connected by a qualified 

electrician. After installation, have the electrician show you how to disconnect power from the appliance.
You must use a single-phase, 120/208 VAC or 120/240 VAC, 60 Hertz electrical system. If you connect to 

aluminum wiring, properly installed connectors approved for use with aluminum wiring must be used.
Effective January 1, 1996, the National Electrical Code requires that new construction (not existing) utilize 

a four-conductor connection to an electric oven. When installing an electric oven in new construction, 

a mobile home, recreational vehicle or an area where local codes prohibit grounding through the 

neutral conductor, refer to the section on four-conductor branch circuit connections.
Check with your local utilities for electrical codes which apply in your area. Failure to wire your oven 

according to governing codes could result in a hazardous condition. If there are no local codes, your 

oven must be wired and fused to meet the National Electrical Code, NFPA No. 70 – latest edition, 

available from the National Fire Protection Association.

  ELECTRICAL REQUIREMENTS (CONT.)

This appliance must be supplied with the proper voltage and frequency and connected to an individual, 

properly grounded branch circuit, protected by a circuit breaker or fuse. See the rating plate located on the 

oven frame to determine the rating of the product. 

Use the chart below to determine the minimum recommended dedicated circuit protection:

DO NOT shorten the flexible conduit. The conduit strain relief clamp must be securely attached to the 

junction box and the flexible conduit must be securely attached to the clamp. If the flexible conduit will not 

fit within the clamp, do not install the oven until a clamp of the proper size is obtained.
The 3 power leads supplied with this appliance are suitable for connection to heavier gauge household 

wiring. The insulation of these 3 leads is rated for temperatures much higher than the temperature rating of 

the household wiring. The current-carrying capacity of the conductor is governed by the wire gauge and the 

temperature rating of the insulation around the wire.

  MAKE ELECTRICAL CONNECTIONS

WARNING:

 Switch power off at the service panel and lock the service disconnecting 

means to prevent power from being switched on accidentally. When the service disconnecting means 

cannot be locked, securely fasten a prominent warning device, such as a tag,  

to the service panel.

Place oven on table or platform even with the cutout opening. For a single oven, the platform must support 

200 lbs. (91 kg); and for a double oven, the platform must support 375 lbs. (170 kg). Connect the flexible 

conduit to the electrical junction box as shown below*. Position the conduit in such a manner that it will 

lie behind the unit in a natural loop when the oven is installed**. You will need to purchase an appropriate 

strain relief clamp to complete the connection of the conduit to the junction box.

  * Ovens come equipped with a 40” or 54” long conduit. If a longer conduit is desired, there may be one 

available for your model. To check availability or order parts, call 1.800.GE.CARES.

 ** Double Oven with upper microwave oven we recommend install the conduit to side of junction box as 

shown in illustration above.
