Knob & Tube Wiring Removal

Knob & Tube Wiring Removal

Knob & Tube Wiring is the oldest method of wiring a home —cloth-covered wires are connected with porcelain knobs to secure the wires in place. Wherever the wire passes through a stud or joist, holes are drilled and fitted with porcelain tubes; the wire is threaded through these tubes to prevent them from touching the wood; thus the name — Knob & Tube Wiring.

Is Knob & Tube Wiring Safe?

Knob and tube wiring is NOT safe — for a number of reasons:

  1. It is between 70 – 110 years old. It is worn out. The porcelain knobs and tubes crack or break, old wires sag and fray, and the sheathing turns brittle and falls off, exposing the live wires.
  2. Most homes that were originally knob and tube wiring now have a dangerous combination of knob and tube and modern wiring. The most dangerous problems with knob and tube wiring are caused by trying to add additional wiring to the original system.
  3. Knob and tube wiring is an UNGROUNDED system which is completely unacceptable by today’s standards.
  4. Knob and tube wiring is designed to be strung through open air so the heat can dissipate well. Improved insulation techniques create hazards as loose-fill insulation blown into the attics and walls of older houses will come into contact with the wires creating a serious fire hazard.
  5. Modern appliance plugs get modified in order to make them compatible with the old and outdated 2 prong receptacles
  6. Vastly higher electrical demand causes overuse of extension cords and power bars.
  7. Modern living requires more power than the old system was intended to supply.
