Electrical Requirements - Maytag MMW7730DS Installation Instructions Manual

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.

*L1 includes both the microwave and the oven, and L2 includes
only the oven. Amperage values noted above are for information
purposes only: The units are rated in watts.
Models rated from 7.3 to 9.6 kW at 240 volts (5.5 to 7.2 kW at
208 volts) require a separate 40-amp circuit. Models rated at
7.2 kW and below at 240 volts (5.4 kW and below at 208 volts)
require a separate 30-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 ends of the
flexible conduit 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.
