Electrical Installation
The models stated on the front cover are either dual-
rated, designed to be connected to either 208/240V AC,
60 Hz, 4-wire, single-phase power supply, or rated at
120V AC, 60 Hz and use a NEMA 5-20 plug to connect
to a dedicated 120 V microwave circuit.
208/240 V models may also be combined with some
Bosch Built-in Ovens and can be connect directly to the
combo appliance. To do this, please refer to detailed
instructions with the Bosch Combination Kit.
WARNING
When connected to a 4 or 5-wire, 120/208-Volt 3-
phase power supply; the phase C conductor is not
required for the operation of the appliance.

Electrical Requirements:
o a three prong grounded outlet
o 120 V, 60 Hz, AC only
o 20 Amp electrical supply with a fuse or a circuit
breaker
This product must be connected to a supply circuit of the
proper voltage and frequency. Wire size must conform to
the requirements of the National Electric Code or the
prevailing local code for this rating. The power supply
cord and plug should be brought to a separate 20-amp
branch circuit single grounded outlet. The outlet box
should be located in the area behind the appliance (see
section Cabinet Dimensions). The outlet box and supply
circuit should be installed by a qualified electrician and
conform to the National Electrical Code or the prevailing
local code.
The voltage used must be the same as specified on this
microwave oven. Using a higher voltage is dangerous
and may result in a fire or oven damage. Using a lower
voltage will cause slow cooking. The dealer is not
responsible for any damages resulting from the use of
the oven with any voltage other than specified.
Electrical Connection with Wire Conduit
HMC80251UC
The electrical supply should be a 4-wire single-phase AC.
Install a suitable conduit box (not furnished). An
appropriately-sized, UL-listed conduit connector must be
used to correctly attach the conduit to the junction box.
NOTICE: Local Codes may vary; installation, electrical
connections and grounding must comply with all
applicable local codes.
If local codes permit grounding through the electrical
supply neutral, connect both the white neutral wire and
the bare ground wire from the oven to the white neutral
electrical supply wire.
Electrical Connection
The four-wire connection is preferred, but where local
codes permit, the three wire connection is also
acceptable.
WARNING
When connected to a 4 or 5-wire, 120/208-Volt 3-
phase power supply; the phase C conductor is not
required for the operation of the appliance.
