Electrical installation testing is a practice that has become more important over time. This is due to the increasing complexity of installations in both commercial and residential spaces. When it comes to electrical work, the top priority is always going to be safety. This focus is the reason electrical standards and wiring regulations exist in the first place. Electrical installation testing serves the purpose of identifying any possible deficiencies. These shortcomings could be areas in which an electrical system doesn’t meet regulations.

It’s important to have older electrical systems looked over to ensure they’re still in good working condition. At the same time, new installations need an inspection to make sure they conform to today’s stringent standards. You might also feel inclined to have testing done if you’ve recently purchased a building with preexisting installations. If you’re curious about what makes electrical installation testing so complex, or if you’re wondering why only a professional should be doing it, read on for more information.

There are different phases of an electrical installation to keep in mind. The first step is to perform a visual inspection, which is exactly what it sounds like — an expert will confirm the permanently wired electrical components are compliant with safety regulations. He or she will make sure there are no outward signs of damage, and that the required safety measures are present.

After the visual inspection, electrical testing begins. This is where having a qualified individual working becomes even more critical. Everything from specialized training to safety-oriented clothing is necessary for this aspect. In fact, non-authorized people might have to keep a certain distance away from the testing itself.

The testing will cover a building’s wiring, as well as its various components. This can include electrical panels, outlets, distribution boards and lighting. Essentially, the examination covers all systems that conduct electricity within a building. The electrician will use the tests to make sure every necessary precaution is in place to reduce the risks of injury or death due to electrical shock.

In some cases, the testing will call for exploratory work to complete the job as effectively and safely as possible. Parts of the system might need to be temporarily shut off for this. This means you should make sure you don’t have something important — and electricity-based — going on while the installation testing is taking place.
