6.4 Installing a three-wire connection
Requirements
Where local codes and ordinances permit grounding
¡
through neutral, and conversion of supply to 4-wire is
impractical, the appliance may be connected to the
power supply with a Listed (UL, CSA, ...) 3-POLE, 3-
CONDUCTOR cord kit rated 250 VOLTS, 50 AM-
PERES DEDICATED CIRCUIT, and marked for use
with ranges.
It is the responsibility of the installer to provide the
¡
proper wiring components (cord, wires, etc.) and com-
plete the electrical connection as dictated by local
codes and ordinances, and/or the National Electrical
Code.
The cord kit is required to be attached to the range ter-
¡
minal block with a strain relief which will fit a
1" (25.4 mm) diameter hole.
If not already equipped, the cord must also have
¡
¼" (6 mm) faston closed-loop lugs attached to the free
ends of the individual conductors, preferably soldered in
place.
Disconnect the electrical power at the breaker box.
