6. Prepare Electrical Connection
Verify that wiring to house is adequate.
Contact your local utility company to verify that the present
electric service to your home is adequate. In some
instances, the size of the wiring to the house and service
switch must be increased to handle the electrical load
demanded by the range.
Verify that wiring inside house is adequate.
Most wiring codes require a separate circuit with separate
disconnect switch and fuses either in the main entrance
panel or in a separate switch and fuse box.
Most local building regulations and codes require that
electrical wiring be done by licensed electricians. Be sure
to install your range according to the electric codes in place
in your region.
To prevent electrical shock, the grounding
prong on the range cord should not be cut or
removed under any circumstances. It must be
plugged into a matching grounding type receptacle and
connected to a correctly polarized 240- Volt circuit. If there
is any doubt as to whether the wall receptacle is properly
grounded, have it checked by a qualified electrician.
General Information
Ranges are dual rated for use on either 120/240 VAC or
120/208 VAC. See chart at right for power ratings and
circuit breaker sizes based upon the supply voltage for
each model.
Bosch recommends that the range be installed with a UL
approved power cord set (not supplied). The electrical
rating of the power cord set must be 120/240 volt, 50
amperes minimum. The power cord set shall be marked
"For Use with Ranges." Always use a new power cord.
Alternatively, the range can also be hard wired using
the aluminum terminal lugs included in the literature
pack. If using this connection, flexible conduit must also
be used (not supplied).
Bosch recommends a 50 AMP, 60 Hz, 4 wire circuit;
However, the NEC (National Electric Code) allows for
some ranges
to be installed on a 40 AMP circuit. Refer
to your local electric code requirements in order to
determine the required amperage. Always choose a
range power cord set that is rated for the circuit.
In compliance with the NEC, a separate circuit is also
recommended.
Note: In Canada, the range is shipped from the factory
with the range cord already installed. Proceed to "Steps 8
and 9: Installation - Final Steps"
For installations other than those in Canada, connect the
range cord (or wire conductors) at the terminal block
(More detailed instructions are found on pages 4 and
5). Access the terminal block by removing the cover in
the lower right hand corner of the range back panel
(See Figure 4). Install the strain relief and the proper
connector through the knockout(s) provided. The
electrical supply, including flexible conduit or power
cord, should be restricted to the shaded areas in Figure
3 (previous page.)

The strain relief provided with your range cord
Install Strain Relief
Place strain relief in knockout below terminal block (See Figure
4). Feed range cord through hole and strain relief up to
terminal block. Allow for slack in the cord between the strain
relief and terminal block. Once cord length/ slack has been
adjusted, attach strain relief per instructions included with
strain relief.
Figure 4
The knockout panel (below the terminal block) can be
removed from the range to install the strain relief:
Remove panel from range, install strain relief in
panel and reattach. DO NOT remove entire range
back panel.
Risk of Electric Shock or Fire. Frame grounded to neutral
through a ground strap. Grounding through the neutral
conductor is prohibited for new branch-circuit installations (1996
NEC), mobile homes, and recreational vehicles, or in an area
where local codes prohibit grounding through the neutral
conductor.
For installations where grounding through the neutral
conductor is prohibited, (a) disconnect the link from the
neutral, (b) use grounding terminal or lead to ground unit, (c)
connect neutral terminal to lead branch circuit neutral in usual
manner (when the appliance is to be connected by means of a
cord kit, use 4-conductor cord for this purpose).
Use only cord kits rated 125/250 volts (minimum), 50 amperes
and labeled "For Use with Ranges". Strain relief provided with
cord must be installed per instructions included with cord.
