Question Grounding Whirlpool Heater and Motor

undefined I am running two seperate dedicated 120VAC/15amp dedicated circuits with GFCI ptotection. One line for the Whirlpool Heater and the other dedicated line for the Whirlpool Pump/Motor. I also need to run a #8 AWG copper ground wire from the electrical panel to the bonding connectors on the Pump/Motor and Heater. My question is can I run ONE LINE (Tie them together) #8 AWG copper grond wire "TOGETHER" for Both, the Pump/Motor and the Heater? Thanks Charlie

Are you using conduit or cable? Are you talking about the EGC (the wire from the panel to the outlet)? Are you talking about using one #8 EGC to serve both circuits? Why #8?

Using Cable #12 with ground. 2 each dedicated line's from electric panel to 2 seperate outlet boxes with GFCI outlets one for the Heater and one for Pump/Motor. Pump and Heater has pre-installed 3 prong cords plug which will plug into the two seperate dedicated GFCI outlets. "Mfg Installation Instructions says the following: Install a seperate 120VAC / 15 AMP dedicated circuit with GFCI (Ground Fault Circuit Interruper) protection. With a No. 8 solid copper wire. bond the heater to the homes electrical panel or approved local bonding point. A bonding lug has been provided on the Heater". There is also a bonding lug on the Pump/Motor, can I run one #8 solid copper wire from the heater to the pump/motor and then on to the electric panel. Therefore Tied together? Thanks Charlie

Another misinterpretation of the code by a manufacturer. The intent of the #8 is to bond, not ground. There is a difference.
The #8 can go from the motor, through a bond clamp on a cold water pipe, to the heater. All equipment effectively bonded.

Is you description verbatim? Or is there more?
Approved local bonding point is the water pipe.

Thank you for your answer. My description in Quotes is Verbatim from the MFG. I understand what you are saying. Thanks for your time. Charlie P.S. In the future if the Cold Water Pipe is replaced with plastic what do you recommend for a new bonding point?
