3WIRING REQUIREMENTS AND POWER SOURCE VOLTAGE SELECTION
Wiring Requirements
No other appliance should share the circuit with the microwave oven. If it does, the branch circuit fuse may overload and either cause the oven to heat slower than expected or blow the fuse.
1.For Mode NE-1257
The oven must be on a SEPARATE, 20 Amp, 60 Hz-120V GROUNDED CIRCUIT.
the oven with other than specified voltage.
2.For Model NE-1757
a.This oven must be on a separate, 60 Hz GROUNDED CIRCUIT-minimum 15 amps.
b.The microwave ovens are built to operate on 2 different voltages (230 V or 208 V). Be sure that the voltage selector connector (on the back of the oven) is set for your power supply. Connecting oven to 230 volt line with 208 voltage setting is dangerous and may result in overheating of the electrical components thus shortening their life expectancy or possibly causing a fire or other accident. Connecting oven to 230 volt line with 208 voltage will lower the power output of the oven, resulting in slower heating of the food. Panasonic is NOT responsible for damage resulting from the use of the oven with other than specified voltage.
3.For Model NE-2157
a.This oven must be on a separate, 60 Hz GROUNDED CIRCUIT-minimum 20 amps.

Power Source Voltage Selection
The microwave oven Models NE-1757 & NE-2157 are factory set for 208 V operation. For 230 V operation, the following selection MUST be made.
(Step 1) Unscrew the voltage selection panel cover which is located on the back of the oven. Do not remove any other parts from the oven.
(Step 2) Remove the while connector and plug the black connector into the socket.
(Step 3) Store the unused white connector in the rectangular opening.
(Step 4) Reattach the voltage adjustment panel cover to the cabinet.
For 230 V - Use black connector plug. For 208 V - Use white connector plug.
To go from 230 V to 208 V circuit follow steps 1-4 above, except at step 2, plug the white connector plug into the socket and store the black plug in the rectangular opening.
