I have knob and tube wiring in ceilings. I installed a new sevice breaker panel . Now I am identifieng all wires throughout the house.I am remodeling the house, one room at a time. How do I ''dead end" knob and tube wiring so that when I get to the other rooms I can upgrade the wiring?
Each wire end whose other end is not known to be disconnected must be taped off individually and be in a junction box (or outlet box) with a visible (accessible) cover. Two or more loose ends may share the same box.
A section of wire both ends of which are disconnected may be buried in the wall, preferably with labels at each end.
When you cut away a piece of knob and tube wire little by little, then the box that used to hold the loose end must be relocated to where the loose end now is until you get to a T joint or another outlet box at which time the extra box can be removed for good.
(The T joint, pre-existing, does not have to be enclosed in a new box until two legs are cut away and the third leg therefore becomes a loose end.)
Forget super sized fries. The Washington Redskins could promote healthy eating with First Lady Obama by choosing a (red skinned) turnip for a mascot.
