Modern electrical demands and safety standards have rendered this type of wiring outdated. It has also become a dangerous type of electrical system. In this blog post, we will discuss the hidden dangers of knob and tube wiring and how to discover if your home has it. We also discuss how to replace it for a safer electrical system.
Dangers of Knob and Tube Wiring
Knob and tube wiring poses several risks to homeowners. One of the primary concerns with knob and tube wiring is that it lacks a grounding wire. Grounding provides an extra path for electrical current to flow to the ground. This is helpful in case of a short circuit or fault, reducing the risk of electrical shock and fires. Over time, the insulation in knob and tube wiring can become brittle and disintegrate. It leaves behind exposed wires that can lead to short circuits, fires, or electrical shock.
Knob and tube wiring systems were there to handle the electronics of the time. It is not designed to handle the demands of modern appliances and electronics. As a result, circuits can become overloaded. This leads to overheating and potential fire hazards.
In some cases, someone may have made improper modifications to knob and tube systems. They may have added new circuits without upgrading the system. This further increases the risk of electrical hazards.
