5 Dangers of Knob-and-Tube Wiring in Raleigh

knob-and-tube wiring in North Carolina by Streamline Services

Knob-and-tube wiring is a type of wiring used in America from 1880 to the late 1940s. Recognizable by its white, ceramic knobs shaped like spools, some older homes still use it to this day. However, this type of wiring is very dangerous compared to modern wiring and can pose several different dangers. At Streamline Services, we can tell you why this old wiring is dangerous and provide wiring replacement services.

Here are five dangers that should have you switching away from knob-and-tube wiring:

 

Improper DIY modifications

Most of the unsafe DIY modifications we’ve seen are done with knob-and-tube wiring. One reason for this is because it’s very easy to access it for splicing jobs. Oftentimes, people will forgo electrical tape for masking or Scotch tape in their DIY connections. Even worse, these wires are nowhere near capable of dealing with the fuses DIY rookies use with them. This mistake generally results in the wires overloading and potentially causing electrical fires.

 

Extreme age

In general knob-and-tube wiring can be 70 to 130 years old. Even if it seems like it’s working fine, it doesn’t have the capacity modern homeowners need. Trying to use modern electronics means there’s a high chance of overload and electrical fire. Also, it’s more prone to damage than normal wiring, representing yet another fire risk to homeowners.

 

No grounding wires

Because it’s so old, knob-and-tube wiring is not at all compatible with modern 3-plug appliances. Even if you do plug in something with that third grounding plug, it won’t be grounded. This means anything that you plug in is more liable to take damage from voltage fluctuations and surges. As well as possibly causing shocks, this is yet another fire hazard.

 

Can’t handle moisture

As well as not having grounding, knob-and-tube wiring has no rating to handle moisture. All those other problems it has? Even more dangerous when used anywhere that often gets moisture such as kitchens, bathrooms, and outside.

 

Easy to overlook

These days, knob-and-tube wiring will often get buried in insulation. This pushes it into contact with building materials and other clutter. Since knob-and-tube wiring releases heat freely into the air, this is yet another fire hazard it can cause. Also, this insulation issue is an insurance violation. If you mash your insulation and old wires together, you likely won’t be able to get insurance. The National Electric Code (NEC) states that knob-and-tube wiring must stay away from insulation.
