Modification of requirements 12. (1) If the Inspectorate, upon application being made in writing by any person proposing to make any new installation, alteration or addition to an existing installation, is satisfied that strict compliance with these regulations would involve expenditure out of proportion to the freedom from electrical hazard to be secured thereby it may modify them if satisfied that freedom from electrical hazard can be secured in a more convenient manner.

On completion of every wiring work or installation there shall be carried out the following insulation resistance tests with a direct current voltage in each case of not less than twice the voltage to which the circuits will normally be subject, provided that in the case of medium voltage (250v to 650v) circuits, the test voltage need not exceed 500 volts — c Revised as at 31st day of July, 2011 Page 19 Regulation 50 Electricity Regulations (a) where a test is desired of the permanent wiring before any fitting, accessories, appliances or lamps are installed, the conductors shall be connected together so as to ensure that all parts of every circuit are simultaneously tested; the test shall be made between conductors as a whole and ground: Provided that such test shall be deemed to be satisfied if the insulation resistance is not less in megohms than the result of dividing the number 100 by the outlets (points and switch positions) from the fixed wiring; (b) (i) a test of the completed installation or an addition to or alteration of an existing installation with all fuse-links in place, all switches in the ‘on’ position (including the main switch, if practicable) and all lamps in position; the test shall be made between conductors as a whole and ground: Provided that such test shall be deemed to be satisfied if the insulation resistance is not less in megohms than the result of dividing the number 50 by the number of outlets (points and switch positions) from the fixed wiring; (ii) control rheostats, heating, cooking and power appliances and outdoor electric signs may be disconnected from the circuits during the test, in which case the insulation resistance between the case or frame-work and all live parts of each such rheostat, appliance and sign shall be tested: Provided that such test shall be deemed to be satisfied if the insulation resistance is not less than half megohm; (c) where a whole installation is being tested a lower value than that given by the formula above subject to a minimum of two megohms is acceptable; and (d) where practicable there shall be a test between conductors: Provided that such test shall be deemed to be satisfactory if the insulation resistance is not less than two megohms. 50. Continuity 50. There shall be the following continuity tests of every wiring installation — (a) a test between the connection to ground and any other part of the completed installation in all cases where metal conduits, metallic sheathed cables or armoured cables which have no other metallic sheath are used; and (b) a test between the connection to ground and any part of any grounding lead: Page 20 Revised as at 31st day of July, 2011 c Electricity Regulations Regulation 51 Provided that each such test shall be deemed to be satisfied if the electrical resistance of such conduit sheathing or grounding-lead does not exceed two ohms. 51. Position of s.p. switches 51. A test shall be made on every wiring installation to verify that no single pole switch or circuit-breaker has been fitted in any neutral conductor or ground conductor and, in the case of a non-grounded two-wire system, that every such switch or circuit- breaker is fitted in the same conductor throughout. This test shall not apply to a switch mounted on a portable appliance or to ground fault circuit interrupters. 52. Non-reversible plug sockets 52. A test shall be made of every two-pin non-reversible type plug socket and every three-pin plug socket to verify that the conductors have been connected in accordance with the appropriate provisions of the N.E.C. 53. Ground resistance tests 53. Ground resistance tests will be made in accordance with the appropriate provisions of the N.E.C. 54. Moulded insulation 54. All moulded insulating material shall be capable of withstanding the tests prescribed by the appropriate current edition of the British Standard Specification or equivalent standard. PART VIII - Certification 55. Issue of certificate 55. (1) After having inspected any electrical wiring work or installation, the authorised Inspector, if satisfied that the work has been carried out in accordance with these regulations, shall certify in writing to the licensee, or, where there is no such licensee, then to the party responsible for the supply of electrical energy, that he has duly inspected such work and that the tests are satisfactory, and that to the best of his knowledge and belief the installation may be safely connected with the source from which electrical energy is available. Any authorised Inspector shall, at all times, have the right to inspect and test any electrical installation at his discretion. (2) Nothing in any such certificate shall relieve the owner or occupier of any premises from the obligation to bring any installation into conformity with these regulations if, on any subsequent inspection, any defects are discovered which render such installation electrically hazardous. c Revised as at 31st day of July, 2011 Page 21 Regulation 56 Electricity Regulations (3) Any certificate issued under subregulation (1) shall be delivered only to the licensee for the area concerned or to the party responsible for the supply of electrical energy, as the case may be, and shall, in no event, be handed or delivered to any other person or body. 56. Special connections 56. (1) Notwithstanding anything to the contrary in this Part, the Inspectorate may, in case of urgency, issue a permit authorising an installation to be temporarily connected with the source from which electrical energy is available notwithstanding that any one or more of the hereinbefore prescribed insulation resistance tests have not been satisfied: Provided that no such permit shall be granted unless the installation otherwise generally complies with these regulations and is in the opinion of an authorised Inspector to be reasonably free from electrical hazard; such permit shall be subject to the conditions set out in regulations 36 to 38. (2) On the expiration of the period or extended period for which temporary connection has been so authorised the installation shall be disconnected from the source from which electrical energy is available unless, before such expiration, an authorised Inspector has issued his certificate pursuant to regulation 55(1).
