Your Home Wiring System

Posted on: June 22, 2016

The wiring system in your home is a critical part in your home’s power system. Make sure you are safe.

Domestic electrical wiring systems have evolved over time as technology advances. Depending on the age of your home, you might consider having your wiring replaced by a modern, safe and efficient system.

About 1/3 of all homes in the United States are at least 50 years old and are much more susceptible to electrical fires than newer homes.

Homes built before 1930 most likely have knob and tube wiring that used ceramic knobs to separate wires from combustible framing elements. Today, knob and tube wiring is considered a major fire and safety hazard since the system is not properly grounded. This type of electrical wiring should be replaced as soon as possible.

Aluminum wiring was popular in the US during the 60s and 70s. It is estimated that nearly 2 million homes were wired with aluminum instead of copper between 1962 and 1972. Many receptacles and switches manufactured during this time were not intended to be used with aluminum wires. Aluminum wiring combined with poor installation practices poses a potential fire hazard.

You can determine if your home is fitted with aluminum by inspecting exposed wires to see if they are labeled “AL” or Aluminum. The best way to ensure you do not have aluminum wiring is to call the electrical experts at Midway Services. They will inspect your current wiring system and let you know if it should be upgraded or replaced.
