Knob And Tube Wiring Replacement

Knob and tube wiring replacement is a crucial step toward ensuring electrical safety in older homes. This outdated wiring system, commonly found in houses built before the 1950s, poses significant risks due to its lack of grounding and insulation. Upgrading to modern wiring is essential for preventing electrical fires, improving energy efficiency, and accommodating the electrical demands of today’s technology. By replacing knob and tube wiring with safer alternatives, homeowners can enjoy peace of mind, reduced maintenance costs, and a more reliable electrical system that meets current safety standards.

Why are Knob and Tube Wiring Dangerous?

Age

Knob and tube were used from the 1880s through the 1940s. If your home is running on this outdated technology, it means your wiring system is from the WWII era at the latest. The difference in electricity consumption from that time to today poses a threat to your home. If you have these installed, chances are these are overloaded and may cause electrical fires.

Insulation

Insulation is typically installed over knob and tube wiring. That increases the chances for a fire to break out. The extra layer of rubber cloth insulation leaves little space for heat to dissipate. There could be build up when current is flowing through the wires. This can potentially be hazardous and can lead to serious issues with your knob and tube wiring.

Improper Alterations

A lot of issues with knobs and tubes are due to DIY fixes or an unauthorized handyman. The old wiring system makes it a challenge to find available parts. This often leads to improper solutions and alterations.

Absence of Ground Wire

The absence of ground wire makes the aluminum knob and tube wiring unsafe for modern, three-pronged appliances and devices. This can lead to danger and increase the chances of fire.

Does Not Do Well with Moisture

The aluminum knob and tube wiring are not suitable for moist environments. Exposing it to wet areas can be dangerous, with the possibility of shocking anyone nearby.

FAQ’s

1. What is “Knob and Tube” type wiring?
This is the first generation of wiring in Canada. Shortly after the end of WWII, it was abandoned for “Two conductor/Cloth covered” type wiring. Click here to see the photos. As you can see, this type of wiring uses ceramic knobs to support individual wires running along the wooden beams, and ceramic tubes to pass through wooden beams. The connections are done by splicing, soldering, and taping. This is usually well done, however not very accessible for any future repairs/alterations.

2. Why is it unsafe?
There is no ground wire. This presents a shock hazard and could lead to an electrical fire. It has no temperature rating. This is why the wires above ceiling-mounted fixtures are so commonly compromised. It is a free-air wiring system and was never meant to be covered by insulation.
