Connecting to a Three (3) 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.
NOTE
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 insulating
materials as shown above with a length of No. 4 copper
wire. Securely clamp the wire to bare metal at both ends.
