ELECTRICAL CONNECTIONS
MAKING ELECTRICAL
CONNECTIONS
Effective January 1, 1996, the National
Electrical Code requires that new, but not
existing, construction utilize a four-conductor
connection to an electric range. When
installing an electric range in new
construction, follow the instructions in NEW
CONSTRUCTION AND FOUR-CONDUCTOR
BRANCH CIRCUIT CONNECTION.
You must use a three-wire, single-phase
AC 208Y/120 Volt or 240/120 Volt, 60 Hertz
electrical system with separate ground.
If you connect to aluminum wiring, properly
installed connectors approved for use with
aluminum wiring must be used.
New construction and four-conductor branch
circuit connection
•
When installing in new construction, or
•
When installing in a mobile home, or
•
When local codes do not permit grounding
through neutral:
4-Conductor Branch Circuit
When connecting the cooktop to a
4-conductor circuit, connect the red leads
of the cooktop and the power supply to the
branch circuit red lead; connect the black
leads to each other. Connect the cooktop
white lead to the power supply and branch
circuit neutral leads, which are white or gray.
Ground the unit by connecting the green
conductor of the cooktop to the bare or green
leads of the power supply and branch circuit
(ground leads).

When installing in existing construction built
prior to January 1, 1996, and if permitted by
local codes:
3-Conductor Branch Circuit
When connecting cooktop to a 3-conductor
circuit, connect the red leads of the cooktop
and the power supply to the branch circuit
red lead; connect the black leads to each
other. Connect the green and white leads of
the cooktop to the power supply and branch
circuit neutral leads, which are white or gray.
