Hey guys,

I have often wondered what other EC's are doing with knob & tube, cloth 2wire cable w/no ground are doing, when lets say for example "you pull down an old fixture and find cables with crunchy insulation and/or have no insulation. "?

Get a copy of David Shapiro's "Old Electrical Wiring", published by McGraw-Hill. You will find several options depending on the condition of the old wires.

Creighton Schwan !! We don't get to see much of you very often.

Your paper "Things Are Not Always What They Seem" [EC Mag, Nov. 1999] is mandatory reading for my students.

I tell my customers that getting into K&T is never a sure thing, many dominoes may fall due to one simple task.

Yup! Played dominoes with the 1948ish version of romex last week.

Adding some gfci receps turned into 3 days work,much to the homeowners dismay.

You have to cut back to the good stuff if there is any.

Heres a possible suggestion, Has anyone thought of using High voltage sleeving (Like they use on electric motor connections and leads). Its very durable and comes in many sizes. Just a thought any opinions?

We used to use heat shrink on the old insulation. If the insulation wasn't too bad that was. This way the new heat shrink would keep the old insulation in place.

Where a Light Fixture is concerned, now with it's stated 90C requirements, is there any (approved) alternative to replacing the wiring?
