Modern homes are not typically built with knob and tube wiring, and while it’s not necessarily dangerous, it can be problematic as your insulation deteriorates over time. Because of this, knob and tube wiring should not be installed in or through your insulation.
Speaking of wiring insulation, you should never have wiring installed or pushed through your insulation. It can cause fire hazards if the wires overheat. You should have “open wiring” in your home. Open wiring allows you to have the open airspace that your wiring requires in case of overheating.
Other safety concerns include:
If you have knob and tube wiring, it doesn’t mean your home is at immediate risk of an electrical fire, but it can mean that the electrical system needs to be regularly inspected. This will ensure the knob and tube wiring isn’t corroded, worn, or damaged in any such way. Knob and tube wiring has also been known to make it difficult to get proper home insurance.
When you have knob and tube wiring, it will use a rubber, cloth-like insulation. Over time this insulation can become brittle and begin to crack or flake. When this happens, it can create a huge fire hazard if the wires overheat.
When knob and tube wiring was popular, the amount of electricity used in homes was miniscule compared to homes today. Now, these systems can’t keep up with the amount of electricity the modern world uses and can overheat easily.
Most knob and tube circuits have fewer branch circuits than what we use today, leaving electrical systems at risk of higher levels of currents and an increased risk of electrical fires.
Because the knob and tube wires are made out of porcelain, they are easily cracked, leaving the wires susceptible to fraying.
Most handymen/electricians are not trained on how to properly work with knob and tube wiring. This can lead to hazardous situations when trying to upgrade your electrical system.
Knob and tube wiring is more susceptible to mechanical damage. Only a professional should handle knob and tube wiring issues.
The most appropriate way to handle knob and tube wiring is to have it completely removed and then professionally replaced. As mentioned before, knob and tube wiring was made to last 100 years, but that does not mean it should. Replacing it with modern copper wiring systems will allow your home to be more energy-efficient and keep you up to the current Electrical Safety Code standards.
You will also want to install a brand new electrical panel to make sure your home’s system is able to handle the electrical usage of today’s requirements. Contact our professionals at Attic Projects to get your knob and tube wiring removed and replaced today.
