Fixing Knob and Tube Wiring
Many homes built in the 1880s through the early 1900s included port and tube wiring to carry electric current. We occasionally get a question about replacing that type of wiring like this present one:

“My husband and I’ll Be purchasing a home constructed From the 1920s. The review found there is still Knob and Tube wiring connected to a 200 amp service. The home is roughly 2000 square feet and now we are with a quote on how much it may cost to update the electric.”

If you are contemplating upgrading an old home to Modern circuits, and then this post might explain a little about it. The video that is linked below in the Edison Tech Centeron You Tube will supply you the capability to view more about it for a much better understanding.

Ceramic Knobs
As you can observe in the movie, you may find “knobs” made from ceramic material that were nailed to the wooden structure. When cables were wrapped around the springs, they supplied service for your wiring and then kept it two or three inches away in the wood in the walls or portion of the home. You might even locate ceramic “tubes” which are a couple of inches long. These were used by drilling a hole through a joist or beam and then such as the tube, and then conducting a cable through the tube. He tubing and loops pieces functioned as insulation substance to prevent warm cables from heating the wood and starting a fire.
