Time for dedicated outlets!

Sir cleeds,
If I may, the power company does not supply a ground wire.
You only have three supply wires coming in from your utility/power company.
2 are the supply wires...Positives...one for each half of a 200 amp service or whatever your home has. The third wire is the Neutral wire.
No ground comes to your home.  Your ground is made-up via a 6' copper grounding rod driven in the ground.

Exactly. That's my question.

I misspoke (wrote)? 10-3 would be three conductor with ground. 10-2 is sufficient. Please check this out from Vince Galbo @ MSB.....
