Many older homes constructed before the 1950s were built with open wiring, also known as knob and tube wiring. This system consists of ceramic knobs and wires encased in tubes. Now obsolete, this type of electrical wiring can’t safely handle the electrical demands of modern living. Those who live or work in an older building can have its electrical system inspected by a licensed electrician to determine whether it has knob and tube wiring. Here are some of the reasons you might be required to upgrade your electrical wiring as a result.

About Knob & Tube Wiring

It Increases Your Risk of Electrical Fires

Knob and tube wiring doesn’t contain a grounding source, and as a result, electrical outlets don’t support three-pronged appliances such as refrigerators, washers, and dryers. When homeowners use adapters or attempt to adjust the wiring to accommodate three-pronged devices, they risk overloading their electrical system. The insulation that lines the tube is also a fire hazard. Because most of the wiring is old, it can’t be safely modified. Instead, it must be replaced entirely.

It Doesn’t Meet Electrical Codes

No new homes since the 1960s have been built with knob and tube wiring. Homeowners looking to buy or sell a home with knob and tube electrical wiring need to be aware that it doesn’t meet current electrical safety standards or building regulations. This means most insurance companies won’t issue homeowners insurance for the house until the electrical system is upgraded.
