WHAT IS KNOB AND TUBE WIRING?
Re-Wiring Knob & Tube in North Bay by Blue Sky Electrical & Construction
Knob and tube wiring was an early type of electrical system most commonly used in North America between the 1880s and 1940s. The wires were held together by ceramic knobs and tubes, and the insulation was usually a cotton cloth soaked in asphalt. The hot and neutral wires were kept a distance apart to prevent short circuits.
Knob and tube wiring isn’t inherently dangerous, but because it’s an outdated form of technology, the condition (due to age and energy requirements) may be compromised and lead to hazardous situations.
It’s worth considering replacing knob and tube wiring in your home for many reasons.
Some of the most important reasons to remove knob and tube include:
Risk of fire from flying sparks and cables pressed into the building.
Electric shock from lack of grounded receptacles, light switches, and light fixtures.
Types of compatible power outlets are limited (cannot use GFCI, or Arc Fault power outlets).
Potential damage to electronics due to electrical spikes.
Increased insurance premiums because of the risks associated with knob and tube wiring.
