Winnipeg Knob and Tube Wiring
What is knob and tube wiring?
Knob and tube electrical wiring is the oldest kind of residential wiring and it is now considered antique in the electrical trade. Porcelain knobs guide the wire along its run while porcelain tubes support the wire as it passes through wooden studs and joists. The old-fashioned wire is insulated by paper- or asbestos-wrap and is designed to be air-cooled.
