What You Need To Know About Knob And Tube Wiring
Knob and tube wiring is usually found in homes built about 50 years ago that have not had the wiring updated. Knob and tube wiring gets its name from the insulator knobs used to keep the wires isolated from objects and the ceramic tubes used to line holes through wooden floor joists. You may find it with older 60 amp services.
Although the actual wire used may be no different from that used today for the most part, it consists of only a hot (black) and neutral (white) wire with no ground wire. Both wires must run separately to fixtures as opposed to those used now which are contained within one plastic sheathing.
MY NEW HOME HAS KNOB AND TUBE WIRING, NOW WHAT?
Knob and tube wiring can be safe and functional. Hire a qualified electrician to inspect the wiring to determine its safety. With proper documentation from a certified electrician many insurance companies will readily insure your home. While I have safely owned many homes with knob and tube, there are some issues to be concerned about, such as, the fact that there is no ground wire, which may be an issue for today’s lifestyle, high electricity usage and technology. Also, there are potential fire hazards with the breakdown of the insulation around the knob and tube wiring that comes with age, and should the black and white wires make contact.
In recent years some home insurance companies have begun to refuse to insure homes with knob and tube wiring, however, there are companies that continue to offer regular priced policies for homes with knob and tube, and others who ask a premium for this insurance. If you have any qualms about the safety of your knob and tube wiring, you can hire an electrician to update your home wiring. Be sure to get a quote, and expect to pay more to update a two- or three-story home than you would for a bungalow. Keep the receipt to show prospective buyers when it comes time to sell.
