Updating knob and tube wiring

05-Jun-2017 15:51

My clients decided that this house wouldn’t work for them as a result, and I asked them to reconsider.

“This is a 0,000 asset you’re looking at, and you’re worried about, maybe, ,500 in custom-closet renovations?

Knobs are used to clamp the wire to the structural member, while tubes are placed in holes in the structural members to prevent the wire from chafing.

These wires are connected by being soldered together and wrapped in electrical tape.

Let’s take a look at what they are, why they’re bad, and whether the response is overblown.

Try to be a little more careful than the previous owner or electrician who rewired our house: we have a couple of holes in the floor because someone missed the wall!

Do I have even the slightest idea of what I'm trying to ask?

If you need a receptacle that can accept a grounded plug but don't actually have a need for grounding, you have two options: (1) a GFCI-type receptacle marked with the words “No equipment ground,” and (2) a three-prong outlet protected by an upstream GFCI and marked with the words “GFCI protected” and “No equipment ground”.

” They looked at each other, smiled, and shook their heads a bit.

They admitted that perhaps they were being a bit too picky, and that, can be changed, whether minor or major.

The rubber and cloth insulation around the knob & tube wiring breaks down over time creating a potential for shorts. Knob and tube wiring, on its own, is not inherently dangerous. The type of insulation used has a tendency of drying out and falling off the wires, especially in areas for lights, switches and receptacles.
