I'm trying to figure out why these taps would fail. They should be no more dangerous than the original K&T, which I am given to understand is quite safe. The modern tape and solder should be even better than what they had originally.
I think Alan means just poorly made splices, like just loosely wrapping the new wire around the old and taping it up. I doubt any average person would go as far as to solder the joints etc.
OK John, time to fess up, what is most likely to burn my house down?
