I did some rewiring in my control panel and then tested it with my multimeter. At my two 240 vac outlets, I found 235 vac (on) and 0.25 vac (off) and 235 vac (on) and 1.1 vac (off). I was expecting 0.0 vac with the contactors off. I then tested upstream (236 vac) and downstream (0.85 vac)of my main contactor when it was off. Is this kosher or do I have something wrong?
