Why You Should Replace Knob & Tube Wiring

You should seriously consider replacing the knob and tube wiring in your home for the following reasons:

Knob and tube wiring was popular from the 1800s to the 1950s. The knobs are designed to operate in open spaces due to the amount of heat they produce. If the wiring is insulated, the knobs can overheat and result in a fire.
Knob and tube wiring does not contain a ground wire. With no grounding, your home is at risk of electrical fires. Grounding the system also prevents damage to electrical devices and appliances.
Insurance companies recognize that knob and tube wiring is outdated and hazardous. Therefore they won’t cover any electrical related damage to your home. Providers may not cover the home at all.
Unless an investor is going to flip your house, you’ll have a difficult time selling it. Even if it passes inspection (which it likely won’t), it will raise a red flag with homebuyers.

The Dangers of Aluminum Wiring

Aluminum was popular in the 1940s and 1950s due to the demand for copper during World War II and the Korean War. At the time, it was considered a safe and efficient alternative to copper. Eventually, problems with aluminum wiring became evident:

Aluminum is not durable. It can easily be broken, cut, or damaged in other ways. When aluminum is damaged, it can become exposed.
Unlike copper, aluminum rusts over time. Rust will corrode the wiring and it make less conductive. Thus, it will impede the flow of electricity and lead to other problems.
The constant expansion and contraction in aluminum will result in loose connections at junction boxes or outlets.
For all the reasons listed above, aluminum is hazardous and risky. It can overheat and electrical fires.

NEC Building Codes

The National Electrical Code (NEC), a subsidiary of the National Fire Protection Association (NFPA) sets the minimum standard for electrical wiring every three years. According to Article 394 of the NEC, knob and tube wiring is not acceptable as a general purpose wiring method.

The NFPA has recognized knob and tube wiring and aluminum wiring as sub-par wiring types and materials that pose numerous safety risks. Although some forms of these systems are still allowable under certain conditions, it’s only a matter of time before they will no longer meet minimum standards in any scenario.
