Safety of Knob and Tube

Knob and tube wiring systems present very serious fire dangers. Plus, since these systems are not grounded, you are at risk for electrical shock in the event of a malfunction in one of your devices. Connecting appliances to ungrounded systems can also cause continuous damage over time due to electrical buildup.

Because they are unsafe, many insurance companies will not provide fire insurance to homes with knob and tube. It can also be very difficult to find a mortgage lender willing to offer a loan on these homes.

Knob and Tube Systems Provide Insufficient Power

Knob and Tube wiring systems were installed many years before people had the amount of electrical devices that we had today. Because of this, they were not designed to handle the load typical of your standard modern household. This typically results in blown fuses and tripped circuit breakers.

To try and combat this, some homeowners will oversize their fuses or breakers. Although this may cause it to blow less often, it is very dangerous because the extra electrical current can cause overloading an overheating.

Insulation and Fire Hazard

Whenever insulation is blown or laid over knob and tube wiring, it places the entire home at serious risk for fire. If a home or other building has had insulation installed in their attics over knob and tube, this can be very serious.

Ungrounded Wiring Systems

Knob and Tube wiring systems were never grounded. This can greatly increase your risk of electrical shock, as well as low-level damage to your electronics over time. This type of damage will silently shorten the life of all of your valuable electronics such as microwaves, televisions, computers and more.

By far the greatest danger of an ungrounded knob and tube wiring system is electrical shock. Whenever a device malfunctions, it could lead to an electrical shock that could injure or even kill the person who is shocked.

Can I sell or Insure a Home With Knob and Tube?

While you may be able to do these things, it can be very difficult to find insurers and lenders for homes with knob and tube. In general, you will need to have the home inspected by a licensed electrician in order to get insurance. Many insurance companies will just refuse coverage to these homes in al cases. The difficulty of finding a mortgage lender who will offer a loan on a knob and tube home can also make selling your home very hard.
