04 Jan The Need For Quality Electrical Cables For House Wiring

When doing a home wiring, there are two very important things to always remember; the electrician has to be qualified, and the electrical cables used must be of good quality. Failure to adhere to these two cardinal rules, you risk expositing yourself and loved ones to clear risks and dangers. Electrical fires, short circuits, excess power consumption; all these can be attributed to shoddy works during house wiring. When it comes to picking the ideal kind of wiring cable, copper and aluminium tend to be their favourite. In fact, copper dominates and most homes have used this for their wiring. Aluminium on the other hand is not so popular, for some reasons that we’ll be discussing below.

There are numerous reasons why copper is usually the preferred option for most technicians and electricians. Copper does not corrode easily even when exposed to water and other elements. Corrosion leads to rusting that affects the connectivity in the long run. Corrosion has also been associated to likelihoods of accidental fires. Copper is also easy to install and use including on tiny and small spaces. A thin copper cable can conduct huge amounts of current without losing it or short-circuiting. The only notable disadvantage for copper is perhaps that it is quite expensive. Copper is expensive when you compare it to Aluminium. As a result, some home owners opt for the latter and get a qualified technician who can install it properly and conduct regular inspections.

Aluminium’s most notable weakness like aforementioned, is its corrosiveness. So much so that most insurance companies will even hesitate to insure homes that have used aluminium for wiring. Why? Because it is prone to accidental fires borne from short circuits. Aluminium reacts quickly with water to get corroded. That aside, it is a good conductor of current, and is popular for its lightweight. Most industrial complexes that may have limitations on weight issues when wiring tend to find aluminium very ideal. Aluminium is also easy to work with and can be easily bended especially in corners and other difficult areas that need wiring.


  • Having quality cables is cheaper in the long run because it will mean lesser inspections, and fewer repairs of damaged wires. Copper cables require little maintenance the moment you connect them properly; aluminium on the other hand will require inspections after every few months.
  • As a home owner, you also enjoy the peace of mind that comes from knowing that you used quality cables for your wiring. You don’t have to live on the edge worrying when the next fire breaks out in your premises.
  • Like we mentioned before, insurance companies also advice most of their clients to opt for quality wiring cables. Copper is the standard and preferred choice for most. Aluminium is said to be a high risk choice due to its corrosiveness. It also requires frequent repairs to damages suffered when it comes into contact with water and other metals.

If you are not so well versed on the best cables to pick, feel free to consult a professional, licensed electrician to guide you through it. Such an electrician will advice you based on your budget, personal preferences. It does not mean that no homes have aluminium wiring after all; it just means that aluminium requires more attention in the form of frequent inspections. Besides, there are aluminium cables that are sufficiently insulated to protect them from any external elements like water.  Ask your electrician to try and explain the pros and cons of each option so you can make up your mind easily.
