KitchenAid 1.4 cu. ft. Capacity Architect® Series II 900 Watts 30" Width Installation Guide

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:

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.

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.
