Re: Double up on ground wire?


It is tripping the breaker. Could be a nail or other issue. Whatever the cause, it's behind the wall.

Not only should you, you are required to ground the circuit extension you added.

You may use the equipment grounding conductor of the dishwasher circuit to do this as long as all of these requirements are met:

1. Your location is using the 2014 or 2017 NEC.
2. Dishwasher circuit is properly grounded and the grounding conductor is of sufficient size for the circuit you're extending.
3. Dishwasher circuit and extended circuit both originate from the same breaker panel.
4. The extended circuit is protected with an AFCI (or AFCI/GFCI) breaker.

Are you attaching this red conductor to the open screw terminal on the hot side of the existing receptacle? Does the receptacle have the connection tab intact?

That last question is a great one! That never occurred to me.
