Working with knob and tube
March 12, 2005 12:54 PM Subscribe
My house still has some knob and tube wiring. I am concerned, in particular, with the ceiling light fixture in my home office where I just installed a new light. Neither wire was marked as hot or neutral, and my voltmeter read the same thing no matter which way I touched the wires. So I figured I had a fifty-fifty chance of getting it right. Will anything bad happen if I got the lamp wires connected to the wrong source wires? How can I tell which wire is which in the future?
