So, there is no ground that I know of, if I understood this correctly.
That's why I asked if you guys ADD a ground wire in this situation?

The ground is a must, for safety. At one time, it was allowed to run
the timer current though ground. A neutral conductor is now required
for that current.


I've been trying to figure if the cold wire of a
three wire dryer is a neutral or ground. I'd thought
it was a ground, but some folks on the list and
on the web thought it's a neutral.

The proper term is grounded conductor, and it is white.

The term "grounded conductor" works in the NEC where people eventually
figure out the difference between "grounded" and "grounding".

"Grounded conductor" is stupid in this newsgroup.

And the NEC finally put in a definition for "neutral conductor".
"Neutral conductor" is a "proper term" for the white supply wire.


The grounding conductor is green.

White carries device current/current imbalance.

The green/bare wire equalizes potential and provides a dedicated
fault path for the circuit breaker in case there is a short
to any bonded (to ground) metal surface/raceway where the
conductors are present.

There is no such thing as a neutral in a single phase application.

Nonsense.

A 3-wire residential service is single phase and the neutral carrys the
current imbalance. It is also a "neutral conductor" by the NEC definition.
