Fixed Testing

The Electricity at Work regulations 1989 states that an electrical installation should be designed, installed and maintained in a safe manner at all times. This means that the installation has to be safe throughout its working life and you need to provide evidence of this. The regulations also state that records of maintenance and test results will allow you to accurately monitor the condition of equipment and the effectiveness of maintenance programs.

Fixed Wire Testing involves the testing of electrical services and systems that conduct electricity throughout the building. It covers all of the fixed wiring including such items as the main panel, wiring that feeds the sockets, wiring that feeds the lighting, consumer units and distribution boards together with other fixed equipment like air conditioning. A series of tests is carried out on each circuit and an extensive visual inspection is undertaken. The results are checked against values provided by British Standards 7671 for compliance.

Guidence note 3 States;

"Where diagrams, charts or tables are not available, a degree of exploratory work may be necessary so that inspection and testing can be carried out safely and effectively. A survey may be necessary to identify switchgear, controlgear, and the circuits they control."

In practice this means that Engineers carrying out the testing should initially aim to correctly identify all circuits in an installation by looking at a combination of circuit labelling and previous test information and by carrying out circuit tracing where necessary.

 

"Periodic tests should be made in such a way as to minimise disturbance of the installation and inconvenience to the user. Where it is necessary to disconnect part or whole of the installation in order to carry out a test, the disconnection should be made at a time agreed with the user and for the minimum period needed to carry out the test. Where more than one test necessitates a disconnection where possible they should be made during one disconnection period.
A careful check should be made of the type of equipment on site so that the necessary precautions can be taken, where conditions require, not to disconnect or short-out electronic and other equipment which may be damaged by testing."

The results and extent of periodic inspection and testing should be recorded on a Electrical Installation Condition Report and provided to the person ordering the inspection. The report must include the extent of the work, limitations, details of defects and dangerous conditions, and schedules of inspections and test results.
Immediately dangerous conditions should be rectified or reported without delay to the relevant duty holder. Other recommendations and observations should be reported using a numbering system to indicate the severity of each observation.
