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
microwave oven is properly grounded.
This microwave 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.
A copy of the above code standards can be obtained from:

Electrical Connection
To properly install your microwave oven, you must determine the
type of electrical connection you will be using and follow the
instructions provided for it here.
■
Microwave 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 on the right-hand microwave oven frame.
■
When a 4-wire, single phase 208/220 volt, 60 Hz, AC only
electrical supply is required, a 20-amp maximum circuit
protection is required, fused on both sides of the line.
■
A time-delay fuse or circuit breaker is recommended.
■
Connect directly to the fused disconnect (or circuit breaker
box) through flexible, nonmetallic sheathed, copper cable
(with grounding wire). See “Make Electrical Connection”
section.
■
Flexible cable from the microwave oven should be connected
directly to the junction box.
■
Do not cut the conduit. The length of conduit provided is for
serviceability of the microwave 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.
For a permanently connected microwave oven:
The microwave oven must be connected to a grounded,
metallic, permanent wiring system, or an equipment
grounding conductor should be run with the circuit
conductors and connected to the equipment grounding
terminal or lead on the microwave oven.
