  • Your home is 30 or more years old. In any home built before 1985, electrical wiring could be old and outdated.How long does electrical wiring last? Electrical wiring lasts anywhere from 50 to 70 years. Certain things can affect and accelerate the decline of the wiring include:

Understanding the Benefits of Installing Copper Wiring in Your MD Home

benefits of copper electrical wiring

If you’re updating your electrical wiring and your home was built when bell bottoms were in fashion, chances are your home has aluminum wiring. Aluminum wiring was installed between 1965 and 1973, because it was cheaper than copper. Unfortunately, it was far inferior in terms of safety. Copper wiring has been in use since the 1820s, and it still stands as the ideal electrical wiring material. Here are some of the reasons why:

  • Ductile and Malleable. Because copper is so ductile, it can easily be hammered into a thin wire for electrical needs. Its malleability allow it to be bent into shape. Both of these make it a simple solution for electrical wiring needs.
  • Excellent conductor. Copper conducts electricity better than any other non-precious metal. This is an essential component for electrical wiring.
  • Noncorrosive. Copper wiring is non-corrosive, which means it won’t rust and degrade even in difficult environments. That’s why copper wires can last up to 40 years, or even more.

With these excellent properties, it’s no wonder that copper has been a staple in electrical wiring for decades. If you’re wondering when to replace electrical wiring, take a moment to learn what type you have.

The Differences Between Copper and Aluminum Electrical Wiring

The benefits of copper are obvious, but is aluminum really a problem? Aluminum was commonly used in the 60s and 70s, but since that time a number of problems have been found associated with it. For instance, aluminum, unlike copper, is able to react to other materials used in home electrical systems in outlets, light fixtures, and splices. This reaction causes the aluminum to oxidize, deteriorate, overheat, and catch fire. In other words, living with aluminum wiring is like living inside a serious fire hazard, which is why you need to know when to replace electrical wiring.

Yet that’s not the only risk. Aluminum also has high electrical resistance, so it’s difficult for current to flow through it. This means an aluminum wired home will have more electrical losses than one that’s wired with copper. The CPSC estimates about 2 million homes were built with aluminum wiring before this risk was discovered. Many of these homes are in Maryland, Virginia and D.C. If your home was built during this time, then chances are high it was built with aluminum wiring.

If you suspect that your home may have aluminum wiring, don’t delay. You need to address this problem right away to ensure your home is protected from the fire risk associated with aluminum wiring.
