Any pics of the new install? I enjoy "make-overs" (and in this case...it IS "Extreme Edition!")

Actually, I don't have any pix of this install. It's for a friend, and he will be renovating the attic soon. The house was built in 1915.

The attic has a very high roofline, remnants of an old radio aerial, and knob-and-tube. We decided to leave the k&t for now since he wants to reinforce the ceiling joists to make a proper floor. We're going to put a subpanel up there and then figure out where to put the stairs. Next time I go over there, I will get some pix.

Amazingly enough, the branch circuits that were added were not at all bad. All NEMA 5-15 receptacles, and the only ones that weren't grounded were the ones that were added to the k&t circuit.

There was one thing in the branch circuitry that was as scary as that feeder! In the bathroom, there was a 3-way switch wired as a single-pole, going to the light. The installer must have known that there is supposed to be a ground screw on the switch, so the bare wire of the NM cable was wired to the unused traveller terminal! [Linked Image]

Since the feed was from k&t, the ground wire went nowhere, and was randomly energized whenever the light was off!

I disconnected that wire. We will be fixing it properly when we finish the attic.

saw that myself once on a service call on an outside light.. the tenant complained of recieving a shock when she touched the light barefoot after hosing off the patio (!!) I never would have believed it had I not seen it with my own eyes...
