2. Remove the cap from the conduit access hole in the
side of the oven-mounted junction box.
3. Guide the wires from the conduit cable (coming from
the speed microwave oven or steam convection oven -
at the arrow in the following illustration) through the
hole in the oven-mounted junction box. There are four
wires from a speed microwave oven or three wires from
a steam convection oven (no white wire from a steam
convection oven).
4. Snap the conduit connector into the hole by pressing it
in until it clicks into place.
5. Follow the wiring diagram label (at the arrow in
following illustration) and match and connect each wire
by color to the wires attached to the wiring block inside
the oven-mounted junction box. Push the bare end of
the wire until it is snug in the wiring block then tighten
down the retaining screw on each wire. Tighten
securely, but do not overtighten. See previous
illustration for finished appearance.
6. Replace the oven-mounted junction box cover and
tighten the two screws holding it in place. Tighten the
screws securely, but do not overtighten.

Electrical Installation

The assembled combination oven should be moved in front
of the cabinet opening and the power cable from the lower
oven should be connected to the cabinet junction box.

All model ovens on the front cover of this installation
instruction manual are dual rated, designed to be
connected to either 208 or 240V AC, 60 Hz, 4 wire, single-

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.
Important: 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
green ground wire from the oven to the white neutral
electrical supply wire.
Electrical Connection to Main Power
Supply
The four-wire connection is preferred, but where local
codes permit, the three-wire connection is also acceptable.
