Any</p><p>defects or departures from BS7671 (The Wiring Regulations), that may give rise to</p><p>danger found will be itemised in the report.</p><p>&nbsp;</p><p><strong>&nbsp;</strong></p><p><strong>Personnel</strong></p><p>Only Inspecting Engineers who hold the <em>City and Guilds 2391 Qualification in the</em></p><p><em>Inspection and Testing of Electrical Installations </em>and the <em>City and Guilds 2382</em></p><p><em>Qualification in Requirements for Electrical Installations (BS7671:2008) </em>will be</p><p>employed on site to carry out the inspection and testing of the electrical installation.</p><p>Inspecting Engineers may be assisted by staff without the above qualifications but they</p><p>will be directly supervised by the Inspecting Engineer.</p><p><strong>&nbsp;</strong></p><p><strong>Installation Records</strong></p><p>The client will be requested to supply any drawings, diagrams, circuit charts, design data</p><p>or other records for the installation to be inspected and tested that are held by the client.</p><p>Previous test certificates and reports held by the client will be requested for information.</p><p><strong>&nbsp;</strong></p><p><strong>Preparation</strong></p><p>This service requires the electrical installation to be isolated from the supply to permit the</p><p>safe inspection and testing of the installation. The client will be requested to switch off</p><p>and unplug any appliances prior to commencement of the survey. The client will also be</p><p>requested to shut down and switch off any computers, servers, hubs, communication</p><p>systems and other IT equipment to permit disconnection of the electrical supply and</p><p>testing of the installation.</p><p><strong>&nbsp;</strong></p><p><strong>Extent of the Installation to be Surveyed</strong></p><p>The fixed low voltage electrical installation from the company supply intake position,</p><p>distribution boards, distribution circuits and final circuits up to the equipment terminals</p><p>excluding:-</p><p>&nbsp;</p><p><strong>1. </strong>Telephone, alarm, CCTV, data, intercom, call system wiring, heating control</p><p>wiring circuits.</p><p><strong>2. </strong>Portable appliances.</p><p><strong>3. </strong>Emergency lighting systems other than the low voltage supply to any system.</p><p><strong>4. </strong>Any lift or hoist installation.</p></li></ul><p><strong>5. </strong>Medical or laboratory equipment.</p><p><strong>6. </strong>Equipment such as building services plant, motors and control equipment other</p><p>than to confirm earth continuity of readily accessible plant.</p><p><strong>7. </strong>Lightning protection systems other than to confirm any required main protective</p><p>bonding.</p><p><strong>8. </strong>Any high voltage equipment.</p><p><strong>9. </strong>Any equipment belonging to the electrical supply company or meter operator</p><p>other than a visual inspection of the outside of any readily accessible equipment.</p><p><strong>10. </strong>Servers, computers or other IT systems.</p><p>3</p><p><strong>11. </strong>UPS and Power Factor Correction equipment other than the visual inspection of</p><p>the readily accessible outer parts.</p><p><strong>12. </strong>Radio transmitters or receivers including mobile telephone equipment.</p><p><strong>13. </strong>Any potentially explosive areas such as fuel pumps, gas, paint and liquid fuel</p><p>storage areas and paint spray booths.</p><p><strong>13</strong>. Any part of the installation not in service at the time of the inspection and testing.</p><p><strong>&nbsp;</strong></p><p><strong>Limitations of the Inspection and Testing.</strong></p><p><strong>1. </strong>Only those parts of the installation that can be readily and safely accessed by the</p><p>Inspecting engineer will be inspected or tested.</p><p><strong>2. </strong>No part of the installation containing asbestos, or substance having the appearance</p><p>of asbestos, will be dismantled for inspection or testing.</p><p><strong>3. </strong>No insulation resistance testing will be carried out between live conductors due to</p><p>the possible presence of any electronic devices. Where a distribution board can be</p><p>safely isolated the insulation resistance will be measured between live conductors</p><p>and earth for whole distribution boards to verify compliance with BS7671:2008.</p><p>Alternatively where the distribution supply conductors are suitably arranged a live</p><p>earth leakage test will be carried out using a sensitive clamp meter to verify the</p><p>total earth leakage for the board. This will indicate the integrity of the final circuit</p><p>insulation resistance.</p><p><strong>4. </strong>Where the means of earthing for the installation cannot readily or safely be</p><p>disconnected the external earth loop impedance (Ze) will be measured with the</p><p>earthing conductor connected to the installation.</p><p><strong>5. </strong>Earth continuity will be verified by earth loop impedance testing and the value of</p><p>R1 + R2 will be calculated from Zs- Zdb.</p><p><strong>6. </strong>Where design information is not available it will not be possible to verify any</p><p>adjustable settings on circuit protection devices are correctly set.</p><p><strong>7. </strong>All readily accessible sockets and 20% of light fittings and fixed equipment will</p><p>be tested for earth loop impedance and earth continuity</p><p><strong>8. </strong>The highest measured value of earth loop impedance (Zs) will be recorded for</p><p>each type of circuit. Lighting circuits and fixed plant will be earth loop impedance</p><p>tested by injecting a test current from an adjacent socket. If the reading obtained</p><p>is close to the maximum value of Zs permitted in BS7671 for the type of circuit</p><p>protection device a further test will be carried out using the lighting circuit as a</p><p>source of supply.</p><p><strong>9. </strong>Circuits with high levels of harmonics and circuits close to HV/LV supply</p><p>transformers may produce inaccurate earth loop impedance test result readings.</p><p><strong>10. </strong>Where there are insulation resistance defects between live conductors and earth</p><p>this may impact on earth loop impedance readings. Following rectification of</p><p>these earth resistance defects further earth loop impedance tests must be carried</p><p>out to confirm the values of earth loop impedance are satisfactory.</p><p>4</p><p><strong>11. </strong>Equipment above 3M from ground or floor level will not be inspected. A sample</p><p>of this equipment will be tested for earth continuity with an insulated extending</p><p>pole with a test probe attached.</p><p><strong>12. </strong>The assessment of distribution circuits and equipment will generally be carried</p><p>out by inspection. The earth loop impedance of distribution circuits will be carried</p><p>out if it is safe to do so. Insulation resistance testing will not be carried out on</p><p>these circuits if they are constructed using PVC, XLPE cables, power track or bus</p><p>bar systems.</p><p><strong>13. </strong>In the absence of design data circuit voltage drops cannot be verified. Final circuit</p><p>voltages will be sample measured for excessive reductions.</p><p><strong>14. </strong>Where any circuit is not identified, or cannot readily be identified, the circuit</p><p>details will be recorded for conductor sizes, circuit protection devices and wiring</p><p>type. The circuit designation and the test results will be recorded as &ldquo;Not Found&rdquo;.</p><p><strong>15. </strong>Any defects or departures from the requirements of BS7671: 2008 will be</p><p>recorded in the report under the &ldquo;Observations and Recommendations&rdquo; section.</p><p><strong>16. </strong>The resilience of the installation to the partial or total loss power will not be</p><p>tested.</p><p><strong>&nbsp;</strong></p><p><strong>Process</strong></p><p>The survey will cover the following items for inspection and testing.</p><p>&middot; A visual inspection of those parts of the installation that can readily and safely be</p><p>accessed.</p><p>&middot; The supply characteristics.</p><p>&middot; Earth continuity testing.</p><p>Where ring final circuit conductors can be identified a continuity test will be</p><p>carried out.</p><p>&middot; Insulation resistance testing of distribution boards between live conductors and</p><p>earth where the distribution board can be isolated for testing. Alternatively if the</p><p>supply conductors are suitably arranged an earth leakage test will be carried out</p><p>using a sensitive clamp meter to determine total earth leakage for the distribution</p><p>board.</p><p>&middot; The Polarity of supplies to distribution boards, sockets and a sample of lighting</p><p>and fixed equipment.</p><p>&middot; Earth Electrode Resistance Testing if an earth electrode is fitted.</p><p>&middot; An assessment of arrangements for Automatic Disconnection of the Supply.</p><p>&middot; Earth Fault loop Impedance.</p><p>&middot; The operation of Residual Current Devices (RCDs).</p><p>&middot; Prospective Fault Current at each distribution board.</p><p>&middot; Phase Rotation for 3 phase installations.</p><p>&middot; Functional testing of a sample of circuits and equipment.</p><p>&middot; An assessment of the voltage drop in the installation.</p><p>5</p><p><strong>Reporting of any Defects and Departures from BS7671:2008</strong></p><p>Following the testing and inspection of an installation any defects or departures from</p><p>BS7671:2008(2013) that may give rise to danger will be recorded. The defect of</p><p>departure will then be allocated a Recommendation Code depending on the nature of the</p><p>defect or departure. These codes are numbered C1 to C3 and are listed below.</p><p>Code C1. Danger Present.</p><p>Code C2. Potentially Dangerous.</p><p>Code C3. Improvement Recommended.</p><p><strong>&nbsp;</strong></p><p><strong>Overall Assessment</strong></p><p>Following the inspection and testing of the installation the inspector will consider the</p><p>condition and come to a conclusion and make an overall assessment. This overall</p><p>assessment will either be &ldquo;Satisfactory&rdquo; or &ldquo;Unsatisfactory. If there are Code C1 or Code</p><p>C2 defects present the installation will automatically be assessed as &ldquo;Unsatisfactory&rdquo;.</p><p>6</p><p><strong>&nbsp;</strong></p><p><strong>Standards and Reference Documents</strong></p><p>Where appropriate the following standards will be applied and reference documents</p><p>referred to.</p><p><strong>1. </strong>British Standard 7671:2008 (2013) AMD2 Requirements for Electrical</p><p>Installations 17th Edition.</p><p><strong>2. </strong>The Electricity at Work Regulations 1989.</p><p><strong>3. </strong>The Health and Safety Executive Guidance Note GS38.</p><p><strong>4. </strong>The Health and safety at Work Act 1974.</p><p><strong>5. </strong>The Institute of Electrical Engineers Guidance Note 3 (GN3). 6th Edition.</p><p><strong>6. </strong>British Standard EN 61557 Electrical Safety.
