Knob and Tube Electrical Service in Columbus, OH

The knob and tube electrical system was prevalent in home construction from the 19th century up through the mid-20th century. It was favored over superior electrical systems like conduit or armored cable due to its relatively low cost. Knob and tube wiring (more commonly referred to as K&T) is characterized by an exposed single insulated copper wire conductor attached to or run through ceramic knobs and tubes. It is also known for not having any type of grounding system.

Knob and Tube Electrical Service in Columbus, OH

The knob and tube electrical system was prevalent in home construction from the 19th century up through the mid-20th century. It was favored over superior electrical systems like conduit or armored cable due to its relatively low cost. Knob and tube wiring (more commonly referred to as K&T) is characterized by an exposed single insulated copper wire conductor attached to or run through ceramic knobs and tubes. It is also known for not having any type of grounding system. 

Knob and tube electrical wiring was run through the home between joists, crawl spaces, and below flooring. The ceramic knobs were used to hold the electrical wire away from building materials to allow the heat generated by electricity to dissipate in the open air. This is one of the main reasons why most states will not allow blown-in insulation to be used in homes with existing knob and tube electrical systems. 

Due to an increased risk of fire, most states no longer allow residential applications for knob and tube electrical wiring systems. Even knob and tube installations that are still up to code will not hold up under the demands of the modern-day electrical draw of appliances and other electronic devices. 

Likewise, many insurance companies will no longer offer homeowner policies for residences with existing knob and tube. Lenders are also now hesitant to finance homes with active knob and tube electrical wiring.  This is where knob and tube wiring abatement becomes necessary. 

Knob and Tube Wiring

Many homes located in central Ohio still have knob and tube wiring for their electrical system. KMA Electric and Heating & Cooling has efficient solutions for those looking to address their electrical system short of having to  rewire a knob and tube house. One method is to provide an electrical wiring panel with specially designed breakers that offer additional protections for knob and tube circuits. In other cases, (dependent on the insurance company or lender requirements), we may recommend a whole house rewiring. The situation in every home is different.

Whether the house requires a wiring panel or complete replacement, we promise to provide an accurate assessment to our customers regarding the state of their electrical system.
