Old houses often have outdated electrical wiring. And while age does not necessarily make wires unsafe, your electrical system should be checked periodically to avoid potential hazards. Before considering a home re-wiring project, have a licensed electrician assess its condition and ability to handle current loads. Reed Electric, a trusted electrical contractor in North Little Rock, AR, answers some questions about electrical systems in old houses.

What Is A Knob-and-Tube Wiring System?

The oldest type of wiring system used in homes is called knob-and-tube. It was named for the ceramic insulating knobs and tubes that routed two wires along and through the house framing. Black-colored hot and white neutral wires snake through walls and ceilings with insulators keeping them from touching each other. Over time, it becomes difficult to identify which wire is hot or neutral, especially if they are black with dirt and dust.

Why the Need for Inspection?

An old wiring system becomes dangerous with worn-out or damaged wire insulation. It may also be covered with building insulation that can cause it to overheat. These conditions may lead to a house fire, resulting in financial losses and safety hazards. According to the National Fire Protection Association, electrical distribution is one of the leading causes of residential fires. Moreover, electrical failure is a factor in 13% of home fires.

How Can You Tell If You Have Electrical Wiring Problems?

Electrical wiring issues tend to crop up when you least expect them. The electrical system of houses that are more than 40 years old should be checked regularly and evaluated for home re-wiring. Look out for simple signs that suggest wiring issues, such as frequent blown fuses or tripped breakers, dimming or flickering lights, buzzing and discolored outlets and switch plates, burning smells, and sparks from an outlet. Be wary of electrical shocks when you plug in or touch a cord.
