Electrical Testing & Inspection

 

Electrical Testing & Inspection

Every year some 12,500 fires are started through faulty electrical wiring and accessories causing death and injury, therefore it?s in your best interests to have your property electrical tested. Cables, switches, sockets, fuseboards and other equipment deteriorate with prolonged use, so they all need to be checked and necessary replacements or repairs made in good time.

To ensure your safety all Electrical Installations should be regularly tested and inspected to British Standards BS7671 - IEE Wiring Regulations, regularly, in general business premises should be tested every 5yrs and homes every 10 years (or on change of occupancy), with some properties and locations requiring testing more frequently.

Contact us if you are unsure or unfamiliar with the correct use of your electrical installation or if you would like advice on whether your property requires testing.

Electrical Testing & Inspection

Look out for warning signs of dangerous wiring; Hot plugs and sockets or scorch marks. Fuses that blow for no obvious reason and old style fuse boards with rewirable fuses, Lights flickering, extension leads and adaptors used because of lack of socket outlets. Check your fuseboard/consumer unit it should have a last date inspected on it! - If it hasn't chances are it needs testing.

Check out some of the "horror" images below, we have uncovered when testing electrical installations.

 

Home Buyers Electrical Test & Inspection Survey Report

Home Buyers Electrical Test & Inspection Report

Over half the homes in the UK date back to before 1945, making it crucial for homeowners to check the condition of their electrical installations. EDS recommends that home electrical systems are tested on a change of occupancy or at least every ten years.

Electrical problems will not necessarily be highlighted by a home buyers survey (even if you opt for the full survey, as these are generally carried out by surveyors) and of course it is better to know that things are in order before you commit yourself to the purchase, giving you piece of mind knowing that the property is electrically safe. You should also be able to negotiate the costs of any remedial works from the sale price! Sometimes Banks & Building Societies will insist an inspection is carried out before releasing funds.

We offer two types of inspections, firstly a visual only, which provides a indicitive state of the electrical installation, but involves no testing , (ideal if you have an indication that the property may need rewiring). The second test is the one which we strongly recommend and involves carrying out physical tests on the electrical installation, wiring, accessories, fusebaords etc and is quite involved, generally the test take between 2-6hrs at the end of the testing we submit a detailed report in the form of a Peridioc Inspection Report, together with any remedial works that are required to bring your installation to current standards.

Electrical Testing & Inspection

What is Periodic Testing?

Periodic Testing is the testing of an electrical installation in a building from the main incoming power source through to the the final circuits and distribution points, that could include lighting, power sockets and machinery.

What is a periodic inspection?

Periodic Testing is the testing of an electrical installation in a building from the main incoming power all the way to the final circuits that could include lighting, power and machines. A Periodic Inspection is an inspection on the condition of an existing electrical installation, to identify (in order of priority) any deficiencies against the national safety standard for electrical installations.

A periodic inspection will: * Reveal if any of your electrical circuits or equipment is overloaded. * Find any potential electrical shock risks and fire hazards in your electrical installation. * Identify any defective DIY electrical work. * Highlight any lack of earthing or earth bonding. Tests are also carried out on wiring and associated fixed electrical equipment to check that it is safe. A schedule of circuits will also be provided, which is invaluable for a property.

Why is a periodic inspection needed?

Every electrical installation deteriorates with use and age. It is important for the person responsible for the maintenance of the installation to be sure that the safety of users is not put at risk, and that the installation continues to be in a safe and serviceable condition.

According to Government statistics, each year on average 10 people die and about 750 are seriously injured in accidents involving unsafe electrical installations in the home.

When is a periodic inspection needed?

It is recommended that periodic inspection and testing is carried out at least every: 10 years for a domestic installation. 5 years for a commercial installation. 3 years for caravans. 1 year for swimming pools.

Other instances when a periodic inspection should be carried out are: When a property is being prepared to be let. Prior to selling a property or when buying a previously occupied property.

Who should undertake a periodic inspection?

To give the report credibility and for your piece of mind only fully qualified and competent electricians working for a company approved by the NICEIC, of which EDS is a fully approved. The NICEIC have assessed and approved EDS?s electrical work to ensure that it complies with the national standard for electrical safety.

What happens during a periodic inspection?

Our electrician will check the electrical installation against the requirements of BS:7671 - Requirements for Electrical Installations ( IEE Wiring Regulations) - as amended, which is the national safety standard for electrical installations, and contains around 850 Regulations.

The period inspection will take into account all relevant circumstances including the following factors:

A. adequacy of earthing and bonding.
B. suitability of the switchgear and controlgear e.g. consumer unit e.g. an old fusebox with a wooden back, cast iron switches, a haphazard mixture of such equipment is likely to need replacing.
C. serviceability of equipment e.g. switches, socket-outlets and light fittings e.g. older round pin sockets, round light switches and braided flex hanging from ceiling roses to light fittings, black switches, sockets mounted in skirting boards may require replacing.
D. type of wiring system and its condition e.g. cables coated in black- rubber, black-rubber was phased out in the 1960s or cables coated in lead or fabric are even older and may need replacing (modern cables use pvc insulation).
E. provision of residual current devices for socket-outlets that may be used to plug in electrical equipment used outdoors.
F. presence of adequate identification and notices.
extent of any wear and tear, damage or other deterioration changes in use of the premises which have led to, or might lead to, deficiencies in the installation.

The Approved Contractor will provide a periodic inspection report (PIR) as part of the periodic inspection.

What is a periodic inspection report?

A period inspection report (PIR) is a formal method of recording the findings of the periodic inspection, on at least six pages. Click here to see an sample Periodic Inspection Report

The main purpose of a PIR is to report on the safety condition of an existing installation. Box E on page 1 should describe the overall condition as either 'satisfactory', in which case no immediate remedial work is required, or 'unsatisfactory' which means remedial work is required to make the installation safe to use.

Where a PIR describes the installation as 'unsatisfactory', the next thing to look at is Box F on page 2 `Observations and Recommendations for Actions to be Taken', this is where any departures from BS 7671 are recorded, and a code to indicate the urgency of the action needed is given.

Code 1 Requires urgent attention.
Code 2 Requires improvement.
Code 3 Requires further investigation.
Code 4 Does not comply with BS 7671.

Code 1 indicates a dangerous, or potentially dangerous, condition that requires urgent attention to make the installation safe. Once the necessary remedial work has been completed, an appropriate certificate should be issued to confirm that the remedial work has been carried out in accordance with BS 7671.

We will provide a summary of the inspection in the report, which will give a clear indication of the condition of the electrical installation, taking into account all relevant circumstances.

What happens after a periodic Inspection?

If the report recommends improvements to the installation, a price quotation will be generated for the remedial work.

Thermal Imaging Electrical Testing

Electrical Testing & Inspection

EDS are able to offer Thermal Imaging or Thermography testing for all electrical services and installations.

Thermal Imaging electrical testing can detect and locate the following:
? Overheating & overloading of cables, fuses and control equipment. ? High resistances within switchgear and control equipment. ? Arcing or loose connections ? Identify running temperatures of components, plant or machinery. ? Power & phase imbalances ? Heat sinks or blocked or restricted cooling tubes in high voltage power transformers.

Thermal Imaging is the process of using a special heat/temperature style camera designed to look only for Infra Red (IR) energy, which is effectively heat energy. Unlike the normal light energy or light waves, Infra-Red energy or heat energy is invisible to the naked eye.

Potential problems can be located very quickly and efficiently and without the needs to isolate any power sources, plant or machinery. Infra-Red heat energy is often released by components, plant or machinery whilst performing at their optimum level and is therefore difficult to ascertain by touch whether a component is running at normal temperature or is in fact overheating, whereas with a thermal image the result are instantaneously and the exact temperature of the component can be measured, thus providing an accurate guide to operating levels.

If potential problems are left undetected these can eventually lead to plant or machinery failure and the resulting expense incurred for lost production and downtime, lost orders and could eventually lead to fire.

As Infra-Red heat cannot be seen, the differences between normal operating temperatures and increased operating temperatures due to possible malfunction or overload could not be detected by hand or eye contact, Thermal Image testing is the ideal choice when carrying out routine maintenance visits and can highlight potential problems long before any event occurs, resulting in preventative maintenance as opposed to reactive maintenance and the resulting costs saving associated with such planned maintenance. Thermal Imaging is a non-contact form of testing and is invaluable for predictive diagnostic maintenance work.

 

Does Your Property Need Rewiring?

Electrical Testing & Inspection

As a silent contributor to our daily lives, electricity provides light and warmth, and powers our electrical appliances and equipment. However, most of us take electricity for granted. The cables run inside the walls, above ceiling and under floors, fuse boxes are often hidden away, making it easy to forget that electrical systems do need checking periodically.

Cables, switches, socket-outlets and other accessories deteriorate with use and misuse, and require regular checking. All properties should have their electrical systems checked at least every 5-10 years. There are several signs to look out for that indicate the age of your electrical system and whether your property needs rewiring:

? Cables coated in black rubber - black rubber was phased out in the 1960's. Cables coated in lead or fabric are even older. Modern cables use PVC insulation.

? A fusebox with a wooden back, cast iron switches, a haphazard mixture of circuit boxes.

? Older round pin sockets and round light switches, braided flex hanging from ceiling roses to light fittings, black switches, sockets mounted in skirting boards.

? Wall mounted light switches in bathrooms or wash areas.

If any of these features are present in your property, your wiring system is probably several decades old. Safety is vital, and we strongly recommend that you employ EDS to carry out a indepth survey to ascertain whether your peoprty requires rewiring.

A full rewire will not only bring your property in line with current regulations, it will provide the latest technology in fault protection and allow for a better and safer environment.
