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/rating

control panel along the oven vent.
■
The microwave oven rated 120-/240-volt, 20-amp, has
4 wires (L1, L2, N, and G) in the flex conduit, and should be
connected to a 20-amp maximum-rated circuit, overcurrent
protected on both the L1 and L2 circuits.
■
A time-delay fuse or circuit breaker is recommended.
■
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.
