Office Electrical Wiring – Testing


An Electrical Installation Condition Report (EICR) is the process of testing and inspecting your office’s electrical wiring to check for faults or damage. The EICR test involves a detailed visual inspection as well as various diagnostic tests, such as testing the insulation resistance and Earth continuity, to identify any existing or potential problems.

When carrying out an EICR test, qualified electricians will check for any electrical faults that could be potentially dangerous such as loose connections, exposed wires or overloaded circuits. The tests also involve checking all the sockets and switches in your office to ensure they are wired correctly and that no cables are damaged.

Carrying out regular EICR tests is essential for ensuring the safety of everyone in your office, as well as protecting any valuable equipment. Checking your office’s electrical wiring can also help you to save money by identifying and fixing minor faults before they become major problems.

PAT Testing

A PAT (Portable Appliance Testing) test is a very important procedure that is done to ensure the safety of electrical devices and wiring in your office. The test uses an appliance tester to assess the condition of all electrical appliances or equipment. This includes how insulated and how well it is wired. This will help you determine if there are any issues that need to be addressed before any device is plugged in and used.

To perform a PAT test, the tester will first inspect the electrical wiring of your office by visually inspecting all areas where electricity is used or stored. This includes looking for signs of wear, corrosion, and other problems that may indicate an issue with how it has been wired. The tester will then perform more detailed tests on the wiring, such as checking for correct polarity, loose connections, and other potentially dangerous issues.

Finally, the PAT tester will measure how much electricity is present in each appliance or device to make sure it meets the required safety levels. This is an important step that can help identify any devices that may potentially be hazardous if used. If any issues are found, the tester can provide advice on how to fix them or even recommend an electrician to do the job.
