Bosch HMC87152UC Installation Instructions - Page 8

Electrical Installation - GROUNDING INSTRUCTIONS The models stated on the front cover are either dualrated, 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. 9 WARNING When connected to a 4 or 5-wire, 120/208-Volt 3phase power supply, the phase C conductor is not required for the operation of the appliance.

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. 8 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. 9 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. 9 WARNING When connected to a 4 or 5-wire, 120/208-Volt 3phase power supply, the phase C conductor is not required for the operation of the appliance.
