I've got a nearly full panel in my detatched garage and I've verified all lebeled breakers. However, there's a breaker labeled 'projector plug' that seems to power nothing. There is attatched romex. After testing every plug I could find with that breaker off, inside and out, up and down, I found nothing that was obvioulsy on that circuit. I used a circuit tester and plugged it into all plugs I could find while the appropriate breakers were on/off.
Is there a trick that doesn't take special (expensive) tools for tracing this circuit? I have a studfinder with electric sensing but rubbing it around the whole garage including the ceiling and above apartment just isn't feasable. Had an electrician out for other work as well as a trace, but he half-assed the trace when he was finished with the primary job (but dint't charge me for the trace).
