How Cable Testing is Performed on a Building

Your workplace has a lot of different elements that are vital to the safety and performance of your team. Constructing a building takes a tremendous amount of work, and one of the most important elements is the cabling. In order for your business to run as it should, it’s vital that your cabling does its job. But how can you make sure everything is in order when you can’t even see the cables behind your walls? That’s where cable testing comes into play.


What is Cable Testing?

Cable testing is a basic yet incredibly important test that can help predict potential faults in your workplace. This testing can make sure that your cables are able to handle the amount of electricity that you require, and if there is a potential for a fault, your electrical engineer can address the issue before it becomes a more serious problem.


Importance of Cable Quality Testing

First and foremost, cable testing is important as a preventative measure. Often, an electrical engineer can identify the early warning signs of a fault with a simple visual inspection. Then, they can fix the issue before a fault occurs. If you do encounter a fault, you could potentially be left with expensive repairs or equipment replacements, the risk of injury to your employees, or fines if you’re found in non-compliance with OSHA regulations.

Cable testing can help you save money in the long run. After a fault, you might have to repair your workplace or replace your equipment. However, if a fault risk is addressed early on, you can often solve the problem with a much less expensive approach. And, of course, you won’t have to worry about paying workers’ compensation or OSHA fines in the case of an emergency.


How is Cable Testing Performed?

When you hire an electrical engineer to perform cable testing, they’ll conduct a thorough investigation to make sure everything is in proper working order. They’ll compare your cables to industry standards to ensure that the specifications are in order (meaning that you’re using the proper cables for what your building requires). They’ll also look at the condition of the cables for any damage, perform an insulation-resistance test on every conductor, and check any bolted electrical connections for high resistance.

Then, your electrical engineer will proceed into specific tests that may vary depending on the type of cabling you’re using (whether it’s copper or aluminum).


Types of Cable Quality Tests

No matter what kind of cable you have, your electrical engineer will perform a conductor resistance test and assess the thickness of the insulation. They may also perform a measurement of the overall diameter in some cases.

Beyond these initial tests, there are several broader categories of tests that will be performed. To start, fire testing is important in the case of an emergency. This test will demonstrate how your cables would function during a fire. Cables run the risk of producing lots of smoke and heat during a fire, which can make it difficult to evacuate.

Of course, electrical testing will also be performed. This testing ensures that your cables can safely and efficiently carry the amount of electricity that you need them to. Your electrical engineer will look for potential defects and ensure the quality of the insulation.

Material testing involves looking at the insulation and sheathing, typically by exposing the cables to a high temperature for an extended period. These tests make sure that your cables will continue to function in high-heat scenarios and that the material is safe and reliable.
