Hmm, okay - mesquite's explanation (I like the garden hose analogy to help clarify things) did help expand on the correct, albeit slightly more technically precise answer from dalehileman. So, everyone is correct.
We know that the circuit and the gauge wire (6-3) are all correct, and the actual electrician (vs. home owner wannabe electrician) confirms this to be true. So, at a minimum, I think I'm looking for a reading in the upper voltage (220v) range, and that absent the ability to measure the "load", but in combination with the knowledge that the circuit and wiring is correct - should be enough. This was good, since I learned (and understood) something I clearly didn't have a complete grasp of previously (when it comes to hose diameter and gauge wire - size does
matter . . .). Who knew? Thanks!
