Step 15 – Making Electrical Connections
Effective January 1, 1996, the National Electrical
Code requires that new, but not existing, construc-
tion utilizes 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's red lead;
connect the black leads to each other. Separate
the green and white leads of the cooktop. Connect
the cooktop's 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).

Three-Conductor Branch Circuit Connection
• When installing in existing construction built prior
to January 1, 1996 and if permitted by local codes:
3-Conductor Branch Circuit
When connecting the cooktop to a 3-conductor
circuit, connect the red leads of the cooktop and
the power supply to the branch circuit's 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.
