It seemed like a simple idea: I have a 30A 240V circuit to the pumphouse, feeding two pumps which draw 6A each at startup, and would only start together by malignant chance. Why not put in a subpanel in the pumphouse, and extract a pair of 15A 120V circuits for lights and a couple of GFI-protected plugs in the adjacent barn? Well, here's the punchline: this wiring's been there a long, long time, and only has two conductors, so the subpanel would have no access to the house common or ground windows. I tried wiring the subpanel as a main service panel, with common connected to ground and and the panel grounded to a ground rod, recognizing that my only connection to the transformer center tap would be through ground. Initial indications are none too good. It all looks just fine with no load, but even light loads drop the voltage drastically. Is there something I can do (short of running a new feed from the house), or is this a lost cause? - Martin

I have wired several sets of potlights in a new construction, and all but one situation had power to the switch and then to the lights. In one case though I mistakenly ran power from another switch box, to the first light and then ran cable from the last light to a switch. The power from the other switch box was pigtailed, but I soon realized that connecting blacks and whites together at the three lights completed the circuit. I have now re-wired it in a way that works, but want to know if it is correct. I have taken the white from power and connect whites to whites all the way through to the designated switch. I then run power black to one fixture wire, then the other fixture wire out through black to the next light and so on, so that the last fixture wire connects to the black back to switch. Comments?
