It is the owner’s responsibility to arrange electrical inspections on a periodic basis. This inspection should include both visual evaluation and electrical testing. This should be done once every 3-5 years and also if the occupancy of the building changes.

What Types of Electrical Tests are Commonly Performed on Commercial Buildings?

There are a total of 3 types of electrical tests that are commonly performed on a building that has commercial tenants:

  1. Circuit Breaker Functionality – The commercial electrician will test all isolators, RCDs, and circuit breakers of the building. They will verify that these components are properly maintained and that they are properly labelled. Then, they will test to confirm that the components may be disconnected from the building’s main electrical supply if the need arises.
  2. Protective Conductor Test – This test will ensure that all of the protective conductors that are part of the circuit are working properly and adhere to the legal electrical standards. Furthermore, all will be evaluated to ensure proper connectivity.
  3. Polarity Testing – The test will measure the polarity of the main supply box, the socket outlets, the distribution board, and any type of power supply within the building. This test is performed using a multi-tester or a continuity tester designed for commercial building applications.

What is an Electrical Test Certificate?

An electrical test certificate is a special certificate that is generated by a commercial electrician. It is designed to inform those who evaluate the certificate that the electrical installation, the electrical wiring, and all other components of the electrical system are fully compliant with the standards as outlined in BS 7671.
