In all cases, the initial approach should be to persuade the customer that protective conductors should be provided. Introduction This Best Practice Guide has been produced by Electrical Safety First in association with the bodies indicated on page 2. It is intended to promote best practice, and takes into account the requirements of BS 7671: 2008 By following the guidance it is considered that the installer will have provided protection for the customer so far as is reasonably practicable. The purpose of the guidance is to protect customers and installers against dangerous situations that could arise from an old installation where an installer is replacing a consumer unit or other main switchgear in a home built before 1966 and wired in accordance with the 13th Edition, or earlier, of the IEE Wiring Regulations.
These regulations did not require a protective conductor to be taken to every lighting point and related accessory as is the current requirement. A consumer unit need not be replaced simply because it has rewireable fuses, cartridge fuses or older-type circuit-breakers, as these devices can provide satisfactory overcurrent protection. Similarly, a consumer unit need not be replaced because it does not incorporate RCD protection, as there may be ways to provide this protection other than by replacing the consumer unit. Best Practice Guide Number 6 provides further general advice and guidance for designers, installers, verifiers and inspectors where a consumer unit or other main switchgear is to be replaced in a home wired in accordance with the Sixteenth Edition or earlier of the IEE Wiring Regulations.
Limitation This Best Practice Guide applies only to the reconnection of existing lighting circuits in domestic premises that do not have circuit protective conductors. Legal requirements There is no legal requirement, and no regulation in BS 7671, requiring an existing electrical installation to be upgraded to current standards. However, there is a requirement under the Building Regulations for England and Wales to leave the installation and the building no worse in terms of the level of compliance with other applicable parts of Schedule 1 to the Building Regulations than before the work was undertaken. (Schedule 1 gives the requirements with which building work must comply,) Similarly, the Scottish Building Standards Technical Handbooks, which provide guidance on achieving the standards set in the Building (Scotland) Regulations 2004, require that any work associated with the replacement of a service, fitting or equipment by another of the same general type is to a standard no worse than at present. Main earthing and bonding The installation of a replacement consumer unit must comply with the current edition of BS 7671.
In particular, the installer must, as a minimum, verify that: a) the main earthing terminal of the installation is connected to an adequate means of earthing via a suitably sized earthing conductor b) the main protective bonding is adequate, and c) the meter tails and the distributor’s equipment have adequate current-carrying capacity. Some electricity distributors have requirements regarding the earthing conductor, main bonding conductors and meter tails that exceed the requirements of BS 7671. If any of the above conditions (a), (b)or (c)is not met, the customer should be informed that upgrading is required.
If the customer refuses, the installer should not proceed with fitting the new consumer unit. Reasons for change Planned change Where possible, when an installer is pricing the replacement of a consumer unit, checks should be made at a switch, a lighting point and the consumer unit, to ascertain if circuit protective conductors are present. If the presence of circuit protective conductors cannot be established, it is essential that the customer is advised that there is a possibility that some lighting points may not be earthed. To enable the work to comply fully with the current standard and improve safety, it is necessary to install protective conductors to every lighting point and related accessory. This could involve considerable additional cost, not only in installing new cables, but also in the renewal of decorations unless the customer is willing to accept surface wiring.
In the circumstances where the customer is unable or not prepared to accept either the cost or disruption of re-wiring the circuit(s) or installing separate circuit protective conductors, but still requires a new consumer unit to be installed, the installer needs to carry out a risk assessment before agreeing to replace only the unit. Where cables are lead or rubber-sheathed, then deterioration of the cables is likely to necessitate re-wiring when the consumer unit is replaced. Distress change A distress change occurs when the consumer unit has suffered mechanical or fire damage, has become unusable through overheating or found to be in a dangerous condition with exposed live parts. This situation usually requires immediate replacement of the consumer unit.
It should be explained to the occupant before the consumer unit is replaced that:. if an immediately dangerous condition is found in an existing final circuit, it will not be possible to reconnect that circuit until remedial action is carried out, and.
it will be necessary to return to the installation to carry out any further work that would have been required if the replacement of the consumer unit had been planned. This further work, where required, must be carried out without delay. Risk assessment In all cases, the initial approach should be to persuade the customer that protective conductors should be provided. Where it is proposed to replace a consumer unit, but the customer is unable, or not prepared, to accept either the cost or disruption of re-wiring the circuit(s) or installing separate protective conductors, a risk assessment should be undertaken for the purpose of advising the customer as to the level of risk that would exist on completion of the proposed work. A disclaimer does not absolve the installer from responsibility. The risk assessment requires inspection and testing: Inspection is required to establish whether or not, for the circuits concerned, there are: 1. Class I light fittings or metal accessories 2.
Class I light fittings or metal accessories that are simultaneously accessible to earthed metalwork or extraneousconductive-parts, including conductive flooring 3. Accessible Class I light fittings or metal accessories in special locations or outdoors 4. Lighting circuits that supply socket-outlets that may be used for portable equipment. Testing is required where there are items that fall into categories 1 to 4 above.
There are two tests to be applied (with the main switch off): (1) To establish whether or not equipment is earthed. This test should be applied between the earth terminal in the existing consumer unit and all Class I light fittings and metal plate accessories.
If the resistance value is 1 ohm or less, the equipment may be considered to be earthed. (2) To establish whether or not the insulation resistance of the circuits is satisfactory. A)This test should be applied separately to each lighting circuit between the live conductors (line and neutral connected together) and the earthing terminal in the consumer unit, with that terminal connected to the means of earthing. The resistance should be at least 1 megohm. B)The test should then be applied between line and neutral connected together and the exposed-conductive-parts of every Class I lighting fitting and metal switch plate that Test (1)has shown not to be earthed.
The resistance should be at least 1 megohm. If the circuit does not fulfil the requirements of either (a)or (b), there would be a risk of electric shock if the circuit were to be re-energised. The customer must be advised in writing that this danger exists, and that the equipment must be disconnected from the supply unless it is agreed to install 30 mA RCD protection as part of the work. Action following risk assessment 1. If none of the items in the risk assessment indicate that there is a significant shock risk, the replacement of the consumer unit may proceed. A notice with black letters on a yellow background should be fixed on or adjacent to the consumer unit stating: 3.
If the risk assessment indicates that there is a shock risk due to there being unearthed Class I lighting fittings or metal accessories that can be touched simultaneously with earthed metal parts or extraneousconductive-parts, these lighting fittings and metal accessories should be replaced with Class II lighting fittings and insulated accessories. If the customer declines to have the Class I lighting fittings and metal accessories replaced, the installer should decline to commence the replacement of the consumer unit. If the risk assessment indicates that the insulation resistance is less than 1 megohm, the installer should decline to carry out the replacement of the consumer unit without further investigation and appropriate remedial work. RCD protection BS 7671 does not permit a residual current device (RCD) to be the sole means of protection against electric shock. RCDs should not be used as an alternative to adequate earthing. However, a 30 mA RCD will provide additional protection and could be used where unearthed Class I lighting fittings or accessories are not simultaneously accessible with earthed metal parts or extraneous-conductive-parts.
This method will not satisfy the requirements of BS 7671 and should be listed as such on the electrical installation certificate for the replacement consumer unit. If the customer refuses to accept the advice to install circuit protective conductors to lighting circuits and related accessories, the installer is advised to fit 30 mA RCD protection to the circuit(s) concerned to reduce the risk of electric shock. Where a consumer unit is being replaced, additional protection by means of RCDs in accordance with Regulation 415.1 must be provided to the extent required by the current edition BS 7671, such as for:. socket-outlets (Regulation 411.3.3 refers). mobile equipment for use outdoors (Regulation 411.3.3 refers). cables concealed in walls or partitions, where required by Regulations 522.6.6 to 522.6.8, and. circuits of locations containing a bath or shower (Regulation 701.411.3.3).
Circuits that are to be provided with RCD protection must be divided between a sufficient number of RCDs or otherwise designed as necessary to avoid hazards and minimise inconvenience in the event of a fault (Regulations 314.1 and 314.2 refer). Inspection, testing and certfication The work carried out should be inspected and tested and an electrical installation certificate in accordance with BS 7671, detailing the work, should be given by the installer to the customer. The certificate should state in the noncompliances section that lighting circuits nos. Xxx do not have protective conductors and that the installation of the consumer unit has been carried out in accordance with the recommendations in this Best Practice Guide. The installer should state on the certificate that a full periodic inspection and test of the complete installation has not been carried out. A strong recommendation that the installation has a full periodic inspection and test as a matter of urgency should be made to the customer. Summary Procedure.

Best Practice Guide 2 Guidance on the management ofelectrical safetyand safe isolation procedures for low voltage installations Introduction This Guide explains what needs to be done to make sure workers on site are not exposed to danger when working on or near live electrical systems and equipment in buildings, particularly in the final stages of construction.
Every year, people working on construction sites and on refurbishment and maintenance activities suffer electric shock and burn injuries some of which, tragically, are fatal. Electrical contractors should be aware that many of these accidents are a direct consequence of electricians not implementing safe isolation procedures on low voltage installations (that is, those operating at up to 1000 V a.c. Or 1500 V d.c.). An example of one such fatal incident is given below. Experience shows that electricians employed by electrical contractors are particularly at risk of death or serious injury from electric shock or burns if they fail to follow safe working procedures. To achieve compliance with the legislation explained in this Guide, electrical contractors should not allow or condone dangerous work practices and should arrange for the safe working practices explained in the Guide to be implemented diligently. Whereas this Guide is aimed primarily at electrical contractors and their employees, principal contractors and non-electrical subcontractors have a significant role in managing electrical risks during construction and refurbishment projects.

Principal contractors and their non-electrical subcontractors should make themselves familiar with this Guide to ensure, firstly, that they do not place electrical contractors under pressure to implement unsafe practices; and, secondly, that they understand how their own employees may achieve safety from electrical risks. Legislation The Health and Safety at Work etc. Act 1974sets out the general health and safety duties of employers, employees and the selfemployed. The Electricity at Work Regulations 1989, which were made under the Act, require precautions to be taken against the risk of death or personal injury from electricity in work activities. Duties are placed on employers to ensure, amongst other things, that employees engaged in such work activities on or near electrical equipment. implement safe systems of work, have the technical knowledge, training or experience to carry out the work safely, and are provided with suitable tools, test equipment and personal protective equipment appropriate to the work they are required to carry out.
Under the Health and Safety at Work etc Act, employees are required to co-operate with their employer to enable the requirements of the regulations to be met. This includes complying with any instructions given on matters such as safe systems of work. The Electricity at Work Regulations 1989require that employees themselves comply with the regulations.
The Management of Health and Safety at Work Regulations 1999require employers to make a suitable and sufficient assessment of the risks to the health and safety both of their employees and of other persons arising out of, or in connection with, the conduct of their undertakings. Where five or more persons are employed, the employer must record the significant findings of these risk assessments. HSE Guidance Generic guidance on safe working practices for work on electrical equipment is published by the Health and Safety Executive (HSE) in its guidance note entitled Electricity at Work – Safe Working Practices(HSG85). It provides information on dead and live working and on isolation procedures when working on both Low Voltage (LV) and High Voltage (HV) systems.
This Guide covers LV systems only and is targeted at the work of electrical contractors, particularly in the construction sector. Extra precautions need to be taken when working with HV equipment and circuits, and reference should be made to the detailed guidance provided in HSG85 in such circumstances. The Memorandum of guidance on the Electricity at Work Regulations 1989HSR25 is intended to help duty holders meet the requirements of the regulations.
It will be of interest and practical help primarily to engineers, technicians and their managers (including those involved in the design, construction, operation or maintenance of electrical systems and equipment). It sets out the regulations and gives technical and legal guidance on the regulations. Its purpose is to amplify the nature of the precautions in general terms so as to help in the achievement of high standards of electrical safety in compliance with the duties imposed.
