Fixed electrical installation

Main Switchboard. Emergency Generator. Power Suspension Arrangement for Electrical Work To ensure the electrical work is carried out in a safe environment, the upstream switch or circuit breaker must be switched off and isolated before the electrical work is carried out. Guideline for Periodic Inspection, Testing and Certification PITC Work Registered electrical contractors deploy registered electrical workers of appropriate grade to carry out the electrical work.

Regarding the inspection and testing items, registered electrical workers should carry out the following tests: continuity of protective conductors, including main and supplementary equipotential bonding; continuity of ring final circuit conductors; insulation resistance; polarity; earth electrode resistance; earth fault loop impedance; functions of all protective devices; and functions of all items of equipment. Therefore, they had to clarify with the applicants and request them to make corrections.

Giving wrong information or omitting necessary information in the Certificates often delayed the endorsement of the Certificates. The following are some of the mistakes commonly found in the Certificates: Click to enlarge. Periodic Test for Fixed Electrical Installations. The date should not be later than the date of signature by the registered electrical worker REW 1B.

Should be within one month before the date of signature by the REW 1B. Should be later than the issuing dates of all additional forms WR2A. The date 1C is earlier than 1B or 1A , the date 1B is earlier than 1A , or the date 1A , 1B or 1C is later than the date of the endorsement application. If the upper box is chosen, that means there is no additional form WR2A. If the lower box is chosen, that means an additional form WR2A is attached.

The upper and lower boxes shall not be chosen at the same time. If the upper box is chosen, the signer should be the REC. If the lower box is chosen, the signer should be the owner of the fixed electrical installation applicable when the REW concerned is a full time employee at a regular wage or salary of the owner of the electrical installation. The inspections are vital for the protection against electric shock, electric burns, fires from electrical origin and electrical arcing or explosions initiated or caused by electricity.

We will thoroughly conduct a visual inspection of your fixed electrical installation, including an internal inspection of a sample of isolating devices, including:. At the end of the inspection, you will receive an Electrical Installation Condition Report detailing any observed damage, deterioration, defects, dangerous conditions and any non-compliances with.

Reported defects that receive a C1 classification will be notified to the duty holder, will need to be signed for by the client and must be resolved immediately. As part of this service, you will receive exclusive access to your compliance web portal, showing an online version of your inspection and test records, network drawings and condition reports as well as your overall electrical site compliance and notifications for renewals.

Our web portal is a proactive way to demonstrate your bid to become compliant, and is an invaluable tool should you ever need to provide your reports in defence and for audit purposes. This does not hold true for the vast majority, for which full inspection and testing should be undertaken. Unless and until you suffer an accident then probably nothing will happen.

However, remember that maintenance of a safe electrical system is a legal requirement. Therefore a preventable accident could lead to prosecution, for which there will be no insurance cover. You may also find that an insurance loss adjuster could make much of the fact that you may not have maintained the system adequately which could have led to the claim. Again, this could lead to an unsuccessful claim and a costly experience. The Electricity at Work Regulations applies to all businesses from multi-nationals to sole traders.

So you still need to comply. Because we accurately identify any faults found, the cost of remedy in most cases is not too great. The majority of problems found involve earthing deficiencies, which although potentially very dangerous are not usually hugely expensive to remedy.

A periodic test notice will be applied to your mains board indicating the next due test date. We hold records of all clients, together with re-test dates on our database and remind clients when re-tests are due. Electrical Test Midlands will notify you automatically 3 months prier your testing due date. All your reports will be on our portal which you can access via our website.

The insulation resistance thus measured should not be less than 0. If the insulation resistance is below this value, the wiring section giving that value should be rewired or checked thoroughly until the required value is obtained.

To ensure that the insulation of the cables or wires is not damaged and there is no leakage between them, this test is performed. Before performing this test, the position of the main switch, fuses, switches, etc. The line terminal of the megger is connected to phase terminal of the installation and the earth terminal of megger is connected to neutral wire. The insulation resistance so measured should not be less than 0.

In a low voltage installation, this test is performed to verify that all single pole switches have been connected to phase wire throughout the installation. It is very necessary to place all switches on phase so that when a switch is made OFF, the connected appliance is quite dead. If the switch is connected to the neutral wire then the connected appliance will get phase even if the switch is in OFF position and remain alive.

There is absolutely no difference in the functioning of the switch in either case, but from the safety point of view to avoid shock, etc. The simple method of conducting the polarity test is by using a test lamp. Before performing this test the position of the main switch, fuses, switches, etc.
