Electrical wiring is always evolving. Even as we speak, developers are creating ultra-safe, high-efficiency wiring that can be buried underground and last forever. While the technology is getting better, property owners are having a hard time keeping up.

Below is an informational assessment on the main types of electrical wiring and its pros and cons. We encourage you to read through this if you’re buying a used home, building a new home, or are looking to replace an outdated electrical system. Something to keep in mind: your home may contain different types of wiring that are used for very specific purposes.

●        Aluminum Wire. If you’re home has aluminum wire running through, then we suggest that you have it inspected immediately. Aluminum wire is corrosive and can cause a fire in the home. It also expands with heat and contracts with cold. The constant expansion and contraction can lead to loose connections with outlets and switches.

●        Copper Wire. Copper wire is used for a wide range of applications in both residential and commercial properties. It has impressive tensile strength due to its weight and construction. Although copper is extremely durable, it is also flexible and has a high rate of ductility under tension. Copper will not corrode, and it will not expand and contract like aluminum.

●        Romex Cables. The new kid on the block, Romex cables are quickly becoming the standard for electrical wiring in homes. Romex differs from copper and aluminum in that it is a non-metallic conductor. It also differs from other types of cables, because it can be channeled underground. Romex is used for lighting, outlets, and other similar receptacles.

●        Silver and Gold. Although it is rare, some homes are wired using silver or gold cables. Granted, these two types of metals are costly, but they have their advantages. Silver is somewhat known as a superconductor as it has a higher rate of conductivity than copper. Gold has a low rate of conductivity, but unlike other cables it will not corrode. Unless you’re building an Atomic bomb out back, your need for silver or gold wiring will probably be very low.

●        Alloys. Alloys combine two different types of metal into one to create a healthy conductor. Examples of this would be nickel & chrome, tin & lead, or a bronze combination of copper, tin, and phosphorus. Many of these alloys are used for niche purposes and in highly controlled environments. They are not recommended for residential use.
