If codes permit and a separate ground wire is used, it is
recommended that a qualified electrical installer determine that
the ground path and the 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.
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 number rating
plate. The model/serial number rating plate is located near
center vent of the lower oven. See the following illustration.
● Models rated from 7.3 to 9.6 kW at 240 volts (5.4 to
7.4 kW at 208 volts) require a separate 40-amp circuit. Models
rated at 4.8 kW and below at 240 volts (3.6 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 “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:
1. Connect a section of solid copper wire to the pigtail leads.
2. Connect the aluminum wiring to the added section of copper
wire 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.
