240V FOUR-WIRE CONDUIT
CONNECTION
120/240 VAC
Effective January 1, 1996 the National Electrical
Code requires that new construction (not
existing) utilize a 4-conductor connection to an
electric range.
1. Remove the access plate to gain access to
the electrical junction box.
2. Install the four-wire range conduit and an
appropriate strain relief clamp through
the hole in the junction box.
3. Use an appropriate insulated wire
connector to connect the red, black, and
white wires from the range conduit to the
corresponding red, black, and white leads
from the branch circuit,
4. Connect the green (ground) wire from the
range conduit to the grounding lead from
the branch circuit in like manner.
5. Secure the strain relief clamp around the
conduit and tighten the nut against the
wall of the junction box.
6. Tuck all wire leads into the junction box
and replace the access plate removed
earlier in step 1.
NOTE: A 4-conductor cord is to be used
when the appliance is installed in a mobile
home or when local codes do not permit
grounding through the neutral.
If local codes do not allow grounding
through the neutral, refer to the
illustration below of FOUR-WIRE
CONDUIT CONNECTION.
120/240 VAC
240V THREE-WIRE CONDUIT CONNECTION
1. Remove the access plate to gain access to the
electrical junction box.
2.
Install the three-wire range conduit and an
appropriate strain relief clamp through the hole in
the junction box.
3.
Use an appropriate insulated wire connector to
connect the red and black wires from the range
conduit to the corresponding red and black leads
from the branch circuit.
4.
Connect the green (ground) and white (neutral)
wires from the range conduit to the white (neutral)
lead from the branch circuit in like manner.
5.
Secure the strain relief clamp around the conduit
and tighten the nut against the wall of the junction
box.
6.
Tuck all wire leads into the junction box and
replace the access plate removed earlier in step 1.
