    EDIT: Let me qualify that. I have never specified breakers with GFP in my designs, but we rely on our subcontractors to acquire and install them.

    No, I don't believe any breakers I have installed have had it. The mains in the MDP frequently do, I believe.

    That's news to me, and I have interconnected commercial PV through backfed breakers in large MDP's plenty of times.

    My understanding is that the minimum dead load of 5000# is there to take into account the transient load which would be applied to the tie point by a falling body of much less than 5000# hitting the...

    Maybe, but I am skeptical. The time lapse way the video was shot leaves plenty of time to turn the projector off between frames, or with editing he could have excised frames where the projector was...

    My guess is that he was projecting a photo of Tesla onto his work surface, and he adjusted the camera settings/angle/timing so that it wasn't visible in the video.

    His point is that to any device mounted in a breaker box a resistive heat source like a toaster, for example, can look exactly like a glowing connection in the wall of a house. Both are static...

    In an unbalanced condition, every amp that is added to the neutral is an amp that is subtracted from the phase conductors, so as long as all the phase conductors are in there with the neutral, the...

    I parsed your statement differently than you intended, it appears. You didn't mention raceways, only EGC's, which I interpreted to mean EGC's in general. My bad.

    John Wiles agrees. In a course he gave a couple of years ago he showed us examples of red USE-2 conductors that had been in the sun for a few years. They were bleached white, or nearly so, and the...
