Electrical Requirements
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.
Check with a qualified electrical installer if you are not sure the 
oven is properly grounded.
This oven must be connected to a grounded metal, permanent 
wiring system.
Be sure that the electrical connection and wire size are adequate 
and in conformance with the National Electrical Code, ANSI/ 
NFPA 70-latest edition or CSA Standards C22.1-94, Canadian 
Electrical Code, Part 1 and C22.2 No. O-M91-latest edition, and 
all local codes and ordinances.

Electrical Connection
To properly install your oven, you must determine the type of 
electrical connection you will be using and follow the instructions 
provided for it here.
 ■ Oven must be connected to the proper electrical voltage, 
amperage, and frequency as specified on the model/serial/
rating plate. See the following illustration.
 ■ Models rated from 7.3 to 9.6 kW at 240 volts (6.3 to 8.3 kW 
at 208 volts) require a separate 40-amp circuit. Models 
rated from 4.9 to 7.2 kW at 240 volts (4.3 to 6.2 kW at 
208 volts) require a separate 30-amp circuit. Models rated at 
4.8 kW and below at 240 volts (4.2 kW and below at 
208 volts) require a separate 20-amp circuit.
 ■ A circuit breaker is recommended.
 ■ Connect directly to the fused disconnect (or circuit breaker 
box) through flexible, armored or nonmetallic sheathed, 
copper cable (with grounding wire). See the “Make Electrical 
Connection” section.
 ■ Flexible conduit from the oven should be connected directly 
to the junction box.
 ■ Do not cut the conduit. The length of conduit provided is for 
serviceability of the oven.
 ■ A UL Listed or CSA Approved conduit connector must be 
provided.
 ■ If the house has aluminum wiring, follow the procedure 
below:
 ■ Connect the aluminum wiring using special connectors 
and/or tools designed and UL Listed for joining copper to 
aluminum.
Follow the electrical connector manufacturer’s recommended 
procedure. Aluminum/copper connection must conform with 
local codes and industry accepted wiring practices.
Be sure that the electrical connection and wire size are 
adequate and in conformance with the National Electrical 
Code, ANSI/ NFPA 70-latest edition or CSA Standards 
C22.1-94, Canadian Electrical Code, Part 1and C22.2 No. 
O-M91-latest edition, and all local codes and ordinances.
