Celebrating 20 Years in Business

knob tube wiring

We have the safest forms of electrical wiring so far making it more convenient and easier to use. In the late 1800s and early 1900s, knob and tube wiring type was the standardized method of electrical wiring and was used in all of the houses constructed around that period.

As the name suggests, this type of wiring uses string wires around the house with porcelain knobs throughout giving proper insulation. By the 1940s, new electrical wiring types arrived and yet, there are many old houses in New Jersey that use K&T wiring.

Most of the old homes still use K&T wiring and it becomes quite challenging for electricians to spot the root cause due to its old technology. You need the services of an experienced electric company that can help you with repairs or replacements of K&T wiring. Looking for repairs of Knob and Tube Wiring in NJ?

Common Problems With Knob & Tube Wiring

K&T wiring can have a lot of technical and practical issues considering its differences with modern technology. We have categorized K&T problems into 3 different types.

  • Fewer Power Outlets

The number of electrical gadgets in the home is increasing by each day, and K&T wiring wasn’t devised for this. An extension cord is neither sufficient nor safe in every situation. 

We, at KB Electric, have over 26 years of experience in the electrician industry. We can not only help you increase the number of power outlets, but can also help upgrade your current ones from outdated two-prong outlets to the most current model.

  • Brittle Insulation

The issue of brittle insulation is one of the most addressed problems in the Knob and Tube wiring system. The general form of insulation is done with tubes within the walls and rubber, at the places of installed equipment. This type of insulation can be very brittle, and dangerous, especially in the areas of high heat.

  • Frequent Fluctuations

Fluctuations become very common in households with K&T wiring. The breakers keep tripping and you are left with blown fuses. The entire wiring, eventually, becomes frail which causes frequent tripping and fluctuations.
