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 and
frequency as specified on the model/serial/rating plate. The
model/serial/rating plate is located under the control panel on
single ovens. See the following illustration
A. Model/Serial/Rating Plate
• Models rated from 7.3 to 9.6 kW at 240 V (5.4 to 7.4 kW at 208
V) require a separate 40 A circuit. Models rated at 4.8 kW and
below at 240 V (3.6 kW and below at 208 V) require a separate
20 A circuit.
• A circuit breaker is recommended.
• Connect directly to the circuit breaker box (or fused disconnect)
through flexible, armored, or nonmetallic sheathed, copper cable
(with grounding wire).
• Flexible conduit from the oven should be connected directly to
the junction box.
• Fuse both sides of the line.
• 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.
