David Meiland Posted March 2, 2016 Report Share Posted March 2, 2016 I was at a house this morning where the complaint is high electrical usage. I ended up finding amp readings in a small panel that I don't understand. In the photos, the neutral wire shows about 1.5 amps on it, with the A and B phases showing almost nothing. There are a couple of 120 breakers in the panel for garage lights, and another for a well pump, which was not running. Nothing at all drawing on this panel as far as I could tell. I'm wondering if there is somehow an electrical "leak" going on here, because I'm accustomed to seeing a more logical relationship between these three readings. For instance, in my shop right now, there is 5 amps on the A phase, .9 amps on the B phase, and 4.1 on the neutral. The panel in the photos is in the garage. The service is overhead and comes down the exterior wall of the garage directly behind this panel. The meter, a large disconnect, and a trough are mounted on the exterior wall. There is a conduit going to the house carrying a 400-amp service to a pair of panels there. Not sure if it matters, but there are *big* conductors on the exterior, very close to where my amp clamp is. I normally don't think this will influence the reading at all. No doubt some of you guys can clear this up for me. Thanks in advance.
