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 If your home is running on this outdated technology, it means your wiring system is from the WWII era at the latest.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.

Further, electrical knob and tube wiring is a system that was built on two-prong outlets. Today, many appliances require three prongs. This will require use of an adapter, which may also increase the chances of overloading your electrical system.

The cover on electrical knob and tube is also cause for concern. It can become brittle over time and risk exposing your wires, which is also a fire concern.

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.

Temperature Ratings

Knob and tube electrical wiring was invented before temperature rating tests. Today, the wiring would likely not perform well if placed through trials. Modern electrical systems, however, are designed with cutting-edge, fire-safe materials targeted for high-temperature variants.
