An electrical diagram is located on the side of the control panel assembly (see drawing on page 42).
Electrical diagrams can also be found in this manual beginning on page 43.
The electrical connections are made directly to the terminals of the heating-element contactor, which is
located inside the control-panel compartment on the right side of the oven. A circular opening sized for a
strain-relief fitting is located on the back of the oven near the right side (right as seen from the front of the
oven, see illustration on page 19). Models with two stacked ovens have a separate electrical connection for
each oven.
Use 167°F (75°C) wire for all supply lines.
Ovens are shipped wired for either single-phase or three-phase operation, depending on which was
specified on the factory order. If necessary, an oven can be field-converted to use either single-phase or
three-phase power (see page 39).
