Electrical Installation - GROUNDING INSTRUCTIONS

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 connected 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.

120 V, 60 Hz, AC only

▯

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 manufacturer is not

responsible for any damages resulting from the use of

the oven with any voltage other than specified.

Electrical Connection with Wire Conduit

HMC80252UC

HMCP0252UC

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.

WARNING

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.
