Electrical Faults Are a Safety Hazard
Electrical faults are a health and safety hazard and could be putting your life in danger. Whether in the home or work environment, electrical faults put people at risk of electrocution and electrical fire. A.A. electricians are highly skilled in the practice of electrical fault finding and will locate your fault quickly and with minimal disruption to your routine.Problems must be solved by replacing only defective equipment or components in the least amount of time. One of the most important factors in doing this, is the approach used. An expert troubleshooter uses a system or approach that allows them to logically and systematically analyze a circuit and determine exactly what is wrong.

Fault Location Strategy and Diagnosis
Firstly we design and implement a fault location strategy, and then we explain the fault diagnosis and circuit system fault to you in full detail. If you have an open circuit, short circuit or electronic system fault we will apply an efficient diagnosis and effective solution to the problem.

At A.A. electrical services we utilise the following fault finding strategy:

PREPERATION AND OBSERVATION
Analyse the symptoms of the electrical fault(s).

DEFINE THE PROBLEM
Determine the type of electrical fault: open circuit, short circuit, insulation breakdown.

NICEIC

The key benefits of using an NICEIC-registered Contractor

NICEIC has been assessing the technical competence of electricians for over 50 years. Their aim is to protect everyone who uses electricity from unsafe electrical installations anywhere. To achieve this, they maintain a register of qualified, competent electricians.

They look at a representative sample of the contractor’s work, their premises, documentation, equipment, and the competence of their key supervisory staff. Once contractors become registered with NICEIC, they are re-assessed on a regular basis to ensure that their high standards are maintained.

Enrolment with NICEIC is voluntary, but electrical contractors who are conscientious about the service they offer would consider it a priority to enrol. Over 25,000 contractors are registered by NICEIC, covering the whole of the UK, including Northern Ireland. This means that you’re sure to have a choice of competent contractors operating in your area.

The main benefits of using a contractor registered by NICEIC include:

  • Safety and Competence
  • Compliance with Building Regulations
  • Insurance Backed Warranty
  • Guarantee of Standards Scheme
  • Independent Complaints Procedure

Safety and competence
Electricians registered by NICEIC are assessed on a regular basis to ensure that they are competent and capable of meeting the relevant technical and safety standards, codes of practice and rules of the Schemes they are registered to.

Compliance with building regulations
Contractors registered to NICEIC Building Regulations Schemes are authorised to self-certify their work without hindrance from Local Authority Building Control. This saves you both time and money when undertaking work that requires notification under the Building Regulations.

Insurance Backed Warranty
The NICEIC Insurance Backed Warranty covers work done by contractors registered to the NICEIC Domestic Installer Scheme that is notifiable to Building Control. The purpose of the Warranty is to protect consumers should any work be found not to comply with the Building Regulations under circumstances where the contractor is no longer in business to undertake the necessary remedial work. So remember to ask the contractor for a Part P certificate on completion of work. The certificate will have the IBW details on it.

The financial limit placed on the remedial work is £25,000 for any one installation per period of insurance and the warranty is valid for a period of six years from the date of completion of the original work.

Guarantee of Standards Scheme
NICEIC expects its registered contractors to provide a quality service to their customers and, therefore, endeavour to resolve all complaints about the technical standard of their electrical work. If a customer and an Approved Contractor are unable to resolve an alleged deficiency in the technical standard of electrical work, the customer can make a formal complaint to NICEIC. NICEIC will help facilitate the negotiations between the contractor and the complainant.

Independent Complaints Procedure
The NICEIC Complaints Procedure requires the an NICEIC-registered contractor to resolve the technical deficiency without additional cost to the consumer. However, if the contractor does not undertake the required remedial work, NICEIC’s Guarantee of Standards Scheme ensures it will be done by another NICEIC-registered contractor, at no cost to the customer.

NICEIC operates an independent complaints procedure. If the electrical work of a registered contractor is found to be below the accepted technical standard, NICEIC requires the contractor to correct the work, at no additional cost to the customer. NICEIC is concerned solely with the safety and technical standard of the electrical work carried out by Approved Contractors, and the standard of certification and periodic inspection reports which Approved Contractors are responsible for producing.

Part P

What is Part P?

 
Part P is an electrical safety law within the Building Regulations and was introduced by the Government on 1st January 2005.
 

What is the Aim of Part P?
The aim of Part P is to further enhance the protection of homeowners, improve electrical safety in the home and prevent life-threatening accidents which are caused by faulty electrics. This is to provide peace of mind for the homeowner hiring a company to add some extra sockets etc. and to the potential purchaser so that they know there is nothing in the property that will harm them.

What will happen if I don’t have Part P?
If homeowners do not have Part P approval, they may face problems when trying to sell their home.

It is a criminal offence to carry out DIY electrics that do not comply with Building Regulations and can lead to a maximum fine of £5,000.

What work must be done by a qualified electrician?
The law requires an electrician registered with a Government-approved scheme, such as NICEIC to carry out most electrical work in the home, and once the work is finished, provide you with Part P approval.

DIY electrics must never be implemented in high risk locations such as kitchens, bathrooms and gardens. Unless the homeowner is only replacing accessories, the electrical work MUST be undertaken by a registered electrician or notified to building control.

What work can I do by myself?
Homeowners can only carry out DIY electrics if they can inspect and test that it is safe for use. To comply with the law, homeowners must notify their local building control office before any work is carried out and pay the appropriate fee for an inspection.

The requirements of Part P apply to most electrical work in a home, however there are certain relaxations that apply for minor work.
Minor Work is electrical work that does not involve:
 
1. The addition of a new circuit.
2. Requiring the help of a professional and registered electrician.
3. Requiring notification to the building control office. All electrical work must comply with BS 7671 of the Wiring Regulations.

Periodic inspection Report

See what our customers had to say about our Periodic Inspection Reports here, here, here, and here.

What is a periodic inspection?
An inspection and series of tests to make sure your electrical installation will continue to conform to the national safety standard. A periodic inspection will

  • Reveal if any of your electrical circuits or equipment are overloaded.
  • Find any potential electric shock risks or fire hazards.
  • Identify any defective electrical work.
  • Highlight any lack of earthing or bonding.
Tests are also carried out on wiring and 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?
Electrics deteriorate with use and age – and electricity can be deadly. So it’s vital that people aren’t put at risk.

How often is a periodic inspection required?

Your electrics should be tested every:

  • 10 years for a home.
  • 5 years for a business.
  • 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.
  • Before selling a property or when buying a previously occupied property.

 
Who should do it and what happens?
A suitably qualified electrician, who will check the electrics against the national safety standard, should carry out all periodic inspections. The inspection should meet BS 7671 – Requirements for Electrical Installations (IEE Wiring Regulations). That’s the technical name for the 850 regulations that are checked in this test.

The inspection takes into account all the relevant circumstances and includes the following

  • The adequacy of earthing and bonding.
  • The suitability of the switch and control gear. For example an old fusebox with a wooden back, cast-iron switches, or a mixture of both will need replacing.
  • The serviceability of switches, sockets and light fittings. All of these may need replacing: older round-pin sockets, round light switches, cables with fabric coating hanging from ceiling roses to light fittings, black switches and sockets mounted in skirting boards.
  • The type of wiring system and its condition. For example cables coated in black rubber were phased out in the 1960s, likewise cables coated in lead or fabric are even older and may well need replacing (modern cables use safer pvc insulation).
  • That residual current devices are used for sockets that may be used with outdoor electrical equipment.
  • The presence of adequate identification and notices.
  • The extent of any wear and tear, damage or other deterioration.
  • The changes in use of the premises which have led to, or may lead to, problematic wiring.
The electrician will provide a Periodic Inspection Report (PIR) as part of the periodic inspection.

Portable appliance testing (Pat)

Portable Appliance Testing (commonly known as PAT or PAT Inspection or PAT Testing) is a process in the United Kingdom, New Zealand and Australia by which electrical appliances are routinely checked for safety. The correct term for the whole process is In-service Inspection & Testing of Electrical Equipment.

When people work with electrical appliances, health and safety regulations state that the appliance must be safe, to prevent harm to the workers. Many types of equipment require testing at regular intervals to ensure continual safety; the interval between tests depending on both the type of appliance and the environment it is used in.

Evidence of testing is clearly visible to workers in the form of ‘Passed’ , ‘Tested For Electrical Safety’ and ‘DO NOT USE after’ labels affixed to various parts of the electrical equipment they use.

Portable appliance testing and inspection however was conducted on a 3 month (high risk) and 6 month (low risk) cycle from the early 1960s onwards in government departments under the control of the Department of the Environment Property and Services Agency (circa 1970 to 2000) as the DOEPSA was known and prior to that as the Ministry of Public Buildings and Works (MoPBW) until about 1970.[citation needed]

Extensive record keeping was made into log-books and generally the equipment used was an insulation resistance tester, simple hand tools and visual inspection. This testing and inspection was done under a planned maintenance scheme and predated both the Health and Safety at Work Act 1974 and the Electricity at Work Act 1990 that are frequently quoted as the reason that PAT inspection is done.[citation needed]

In reality neither act nor their corresponding regulations detail PAT inspection as an obligation but rather state a requirement of maintenance of safety and evidence of routine maintenance of all hand-held, portable and plug-in equipment.

It seemed inevitable with the increasing amounts of such equipment in domestic, commercial and industrial environments that the system employed for all government departments would become more formalized and adopted as a method for assuring safety of appliances in the world beyond the civil service departments.[citation needed]

Testing equipment specifically designed for PAT inspections was developed as mobile versions of the equipment used by manufacturers for testing their equipment at the end of the manufacturing process to ensure compliance with the relevant or corresponding BS (British Standard Code of Practice) for that type of appliance.[citation needed]

One other check carried out on high risk equipment such as hand held electrical mains drills class I equipment when issued from a government department stores was the Earth Yeading Test. This test passed a current of 25 A down the earth conductor (the c.p.c. circuit protective conductor as it is currently named) to substantiate that the earth was a sound and valid connection for safe disconnection in the event of a fault occurring.

Regulations on who must have their equipment PAT tested
The Electricity at Work Regulations (1989) requires “All electrical systems shall be maintained so as to prevent, so far as is reasonably practicable, any danger”. This is interpreted as covering the fixed electrical installation as well as portable and transportable equipment connected to it. The Regulations also state “It is the duty of every employer and self employed person to comply with the provision of these Regulations.”

British law (the Electricity at Work Regulations 1989 in particular) requires that all electrical systems (including electrical appliances) are maintained (so far as is reasonably practicable) to prevent danger. Guidance from the Institution of Engineering and Technology (IET, published under the IEE brand) and the Health and Safety Executive (HSE) suggest initial intervals for combined inspection and testing that range from three months (for construction equipment) to one year for inspection and, in many cases, longer periods for testing (certain types of appliance in schools, hotels, offices and shops).

Electrical systems refer to the installation as well as all the appliances connected to it. A qualified electrician or someone that has PAT testing training must inspect the installation annually in any public building and/or a place that people work, private houses do not need this test. The maintenance of the appliances can largely be carried out in-house in many organisations. This can result in cost savings and more flexibility in when PAT testing is carried out.

The European Low Voltage Directive governs the manufacture or importation of electrical appliances. Compliance to this has to be declared and indicated by the display of the CE mark on the product. The responsibility for this lies with the manufacturer or the importer and is policed by the Trading Standards. However, it is important to have a maintenance regime for electrical appliances. The Electricity at Work Regulations (1989) requires that electrical appliances be maintained so that they remain safe during use. The implementation of this is up to employers. The HSE or the local authority is responsible for the policing of this.

Who can PAT test
If you are a competent person and have a basic knowledge of electricity then you can be perfectly capable of testing appliances for electrical safety. It is, however, recommended that an individual wanting to PAT Test attends a course related to the subject matter. There can be much confusion on what needs PAT Testing, what class an appliance is (and therefore which areas to test), and how often appliances legally need to be tested. Proof of a company’s competence in PAT Testing is usually found in the form of a course certificate or qualification. A formal examination process for the topic is operated in collaboration with EAL or City and Guilds (the awarding body) under the authority of the QCA (The Qualifications and Curriculum Authority) who validate and authorise the qualification.

In the UK, There is no requirement to have a formal qualification for persons carrying out PAT Testing. The Electricity at Work regulations of 1989 simply state that inspecting and testing must be carried out by a competent person, however does not mention a benchmark for competency. It has become accepted practice, however, for individuals operating as PAT Testers to hold a 2377-12 City and Guilds qualification.

User checks
Advising the user of potential danger signs can result in problems being picked up before they can result in any danger. For example, if the power cable is frayed or the plug is cracked, users need to be advised NOT TO USE the appliance and report the fault to a supervisor. This information can be put across, say by the use of a poster or in a memo. User checks are always carried out before operation, and the results are generally not recorded, unless a defect is identified.

Formal visual inspections
This is a process of simply inspecting the appliance, the cable and the plug for any obvious signs of damage. According to the HSE, this process can find more than 90% of faults.

Combined inspections and PAT testing
At periodic intervals, it is essential to test the portable appliances to measure that the degree of protection to ensure that it is adequate. At these intervals, a formal visual inspection is carried out and then followed by PAT testing. Note the inside of the plug MUST be checked unless it is moulded or there is an unbroken seal covering the screws (bad internal wiring or an unsuitable fuse would cause the item to be classed as dangerous).

The tests that an individual must carry out to declare an item electrically safe is dependant on the class of construction (shown below). Some of these tests are:
