Electrical Supply; Wiring Requirements - Bosch HBN 44 Series Installation Instructions Manual

ELECTRICAL SUPPLY

Before installing the oven have a qualified electri-
cian verify that your home is provided with ade-
quate electrical service and that the addition of
the oven will not overload the branch circuit on
which it is to be installed. A separate three-wire
or four-wire single phase, 240 Volt, 60 Hz., or a
208 Volt, 60 Hz. branch circuit is required.
Note: For use with 208 V, 60 Hz supply voltage
the wiring must be modified as shown in
Connecting to 208 Volt Circuit.
For hook-up of the oven you will need to have an
approved junction box installed where it will be
easily reached through the front of the cabinet
where the oven will be located. The oven has 3
feet of conduit. Allow two to three feet of slack in
the line so that the oven can be moved if servicing
is ever necessary. DO NOT shorten the flexible
conduit.
ELECTRICAL SHOCK HAZARD
•
The electrical power to the oven branch cir-
cuit must be shut off while line connections
are being made.
•
Do not use an extension cord with this ap-
pliance.
•
Electrical ground is required on this appli-
ance. The free end of the green wire (the
ground wire) must be connected to a suit-
able ground.
This wire must remain grounded to the
oven.
•
If cold water pipe is interrupted by plastic,
non-metallic gaskets, union connections or
other insulating materials, DO NOT use for
grounding.
•
DO NOT ground to a gas pipe.
•
DO NOT have a fuse in the NEUTRAL or
GROUNDING circuit. A fuse in the NEU-
TRAL or GROUNDING circuit could result
in an electrical shock.
•
Check with a qualified electrician if you are
in doubt as to whether the appliance is
properly grounded.
Failure to follow these instructions could re-
sult in serious injury or death.

WARNING

WIRING REQUIREMENTS

When making the wire connections, use the entire
length of the conduit provided (3 feet). The con-
duit must not be cut.
Before making connections make sure the power
is off and read and observe the following:
1. A separate three-wire or four wire, single
phase, 240 Volt, 60 Hz. or 208 Volt, 60 Hz
branch circuit is required for the oven.
2. The oven must be connected with COPPER
WIRE ONLY.
3. In the United States:
Wiring must conform to the National Electri-
cal Code, ANSI/NFPA No. 70 latest edition.
You can obtain a copy of the National Elec-
trical Code by writing:
National Fire Protection Association
Batterymarch Park
Quincy, MA 02269
In Canada:
Wiring must conform to Canadian Electrical
Code C22.1- latest edition. You can obtain
copies of the Canadian Electrical Code by
writing:
Canadian Standards Association

4. Wire size (COPPER WIRE ONLY) and con-
nections must be suitable for the rating of the
appliance per the National Electrical Code
requirements. The flexible armored cable ex-
tending from the oven should be connected
directly to the junction box.
5. The junction box should be located so as to
allow as much slack as possible between the
junction box and the oven so it can be moved
if servicing is ever required.
6. A U.L. listed conduit connector must be pro-
vided at each end of the power supply cable.
