Do you plan to buy an older home because it has character or as an investment? In either case, pay attention to the type of wiring.
Many homes that were built before 1950 and go as far back as the 1800s have what’s known as knob and tube wiring. Knob and tube wiring consist of porcelain knobs with old-style wiring wrapped around it as it runs through the joists, floorboards, and walls. The wiring comprises one hot and one neutral wire with a thick insulation coating.
Problems with this old style of wiring
1. In those days, wiring was designed to carry minimal currents as electricity was used mainly for lighting. Today, we use much more electricity with many electronic devices and appliances plugged into outlets. The old knob and tube wiring isn’t sufficient anymore. It doesn’t adequately supply enough electricity to the home and can pose a significant fire hazard when overloaded.
2. It also doesn’t have a ground wire to protect the home and its appliances during a lightning strike.
3. If rolled or loose-blown insulation has been added to the home, it could cover the wiring. There must be three inches of space between the live wire and any flammables.
4. There may have been newly installed light fixtures or ceiling fans using Romex wiring, which then could be spliced into the knob and tube wiring. These lines, however, weren’t designed for system additions, which could significantly increase the risk of fire.
5. The wiring could have outdated fuse boxes for main disconnects.

Be sure to look in the basement or attic for the fuse box. If you plan to buy the home but see knob and tube wiring or an outdated electrical fuse box, you should consider having it updated immediately.
Contact your independent agent to find the right insurance company to insure your home. Many insurance companies have restrictions on this type of electrical system, and you could have a problem finding a company that will insure your home.
