Fixed Wire Testing

What’s included in Fixed Wire Testing?

The term Fixed Wiring Inspection &Testing generally refers to the inspection & testing activity of the electrical installation within a building. This being the electrical wiring and systems between the incoming electrical supply and final circuits; eg plug sockets, isolators, lights etc.

It would not refer to equipment which is plugged in or wired into spurred sockets or isolators. Please refer to our Fixed Equipment Testing for more information on our website.

A duty holder can demonstrate compliance with the regulations, in respect to their electrical installation, by employing a competent company to carry out an electrical fixed wire inspection and test of their premises. We hope that company would be Electrical test midlands (ETM).

Why do I have to have fixed wire testing tests performed periodically?

The Institute of Engineering and Technology (IET) produce guidance note 3 which incorporates 17th edition IET wiring regulations to BS7671. Section 3 of the guidance covers Electrical Periodic Inspection and Testing.

Periodic Inspection and testing is required because an electrical installation will deteriorate over time due to a number of factors such as; damage, wear and tear, corrosion, excessive electrical loading, ageing and environmental influences.

Guidance Note 3 states that a frequency of periodic inspections should be established, taking into account the type of electrical installation, the type of use, equipment used, the maintenance regime in use, and the environment.

Electrical test midlands are experts in this area and we would be happy to survey your premises, examine previous reports, review your maintenance regime and advise you on the correct frequency and scope of test to ensure your statutory compliance

Question
I’ve been informed the supply company will only give my customer a TT electrical supply to their new industrial unit because of the other multiple paths to Earth that exist. Do I need to install a earth electrode or can I use one of the RSJs?

Answer:
BS 7671 does recognise the use of a RSJ as a suitable earth electrode where it is embedded in the foundations (Regulation 542.2.3). It will also be necessary to treat the RSJ as any other type of earth electrode and measure its resistance to Earth (Regulation 612.7), and ensure it is correctly labelled where your earthing conductor connects to it (Regulation 514.13.1)
