What is Knob and Tube Wiring and Why is it Dangerous?
The knob and tube wiring method was used prior to the 1940’s when building new residential and commercial structures. It got its name from the use of ceramic knobs used to keep in place ceramic tubes. Instead of using three wires like modern electrical work, knob and tube wiring uses two. This means there is no ground wire in the system and no protection when there’s a fault.
One of the biggest issues with this type of wiring is insulation. The insulation with knob and tube wiring is made from rubber which degrades over time and exposes wires. In addition, if knob and tube wiring is in your attic, it can’t be covered by insulation. If your attic was insulated with knob and tube wiring, that poses an extremely dangerous fire hazard. As mentioned earlier, there is also no ground wire to divert electrical currents in case of a fault.
Another common issue is that knob and tube wiring uses two-prong receptacles instead of three. This can greatly limit the use of appliances in your home.
If you’re trying to determine if your home has this old wiring, an easy way to check if your home has knob and tube wiring is to visually inspect. Try looking in your basement or attic, as the exposed ceiling should show you what kind of electrical service you have in your home.

Bobby was terrific! I got the appointment set up with him and he was prompt, professional, and very communicative. Very reasonably priced as well! I would recommend him to family and friends. He installed my electric vehicle wall charger very quickly and perfectly and that’s all I can ask for! Great guy!
