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
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.

The conduit cable, where connected at the oven, swivels.
Rotate conduit cable upward (or downward) and direct
through hole prepared in cabinet to attach to J-Box.
To maintain serviceability, the flex conduit must not be
shortened and should be routed to permit temporary
removal of the oven.
