Me and a few friends got a few minutes of laughs out of this one. If I recall correctly, most communication cable insulation is only rated for around 60V or so. (I know it's too thin for 120V!)

Now that's what I improvising, I'm amazed that CAT 3 cable hasn't fried yet, that light bulb will make a nice mess if/when those ropes break.

Actually, communications cable is rated for (i think) 150v). POTS ring voltage is 90-100v at ~20hz.

24 ga paralleled is the same as 21 ga, so that's about 13 ohm/1000ft. If that run is 20' (up and back down again), that wire presents a resistance of 0.26 ohms. If that's a 240VA 120V load that's 2A of current in the wire, power lost in the wire is P=I^2*R, or about 1W. Despite how bad the installation is, that wire wouldn't even get warm. I still don't approve, and I'm sure this much thought didn't go into this installation. ;\)
