Connecting to a Three Wire Electrical
System with External Ground - Where Local
Codes Permit
WARNING
• Do not connect the green appliance wire to the junc-
tion box or to a cold water pipe unless local building
codes permit.
• Do not ground the appliance to a gas supply pipe or
hot water pipe.
• If connecting the ground wire to a grounded cold
water pipe, connect using a separate copper
grounding wire (No. 10 minimum) and a clamp with
an external grounding screw. The grounded cold
water pipe must have metal continuity to electrical
ground and must not be interrupted by insulating
materials. Any insulating materials must be jumped,
with a minimum, 4 AWG wire to establish continuity
to ground.

Jumpering an Insulated Pipe
If the junction box has been properly grounded by a
licensed electrician, the green (ground) wire from the
appliance conduit may be connected to the junction box
using a loop terminal.
See the diagram on the following page. To connect the
green appliance conduit wire to a grounded cold water
pipe:
1. Separate the wires coming out of the appliance conduit.
2. Connect the white wire from the appliance conduit to
the white (neutral) supply wire in the junction box.
3. Connect the black wire from the appliance conduit to
the black (L1) supply wire in the junction box.
4. Connect the red wire from the appliance conduit to the
red (L2) supply wire in the junction box.
5. Connect the green wire from the appliance conduit to a
grounded cold water pipe as shown. Jumper any insu-
lating materials as shown above with a length of No. 4
copper wire. Securely clamp the wire to bare metal at
both ends.
