The term “British Standard Specification” means a specification issued under that name by the British Standards Institution, and where any such specification is prescribed in these regulations the latest revision thereof or any specification issued in lieu thereof by that Institution prior to the date of enactment of these regulations is implied.

PART 12.—APPLICATION, MODIFICATION, AND EXEMPTION.

APPLICATION.

12–01. These regulations shall apply to all electric lines or works used for generating, transforming, converting, or conveying electrical energy (whether used pursuant to a license or not).

12–02. All additions to or alterations of existing electric lines or works shall be deemed to be new work, and all the provisions of these regulations shall apply to all work done in connection with such alteration or addition.

MODIFICATION AND EXEMPTION.

12–11. All permits, approvals, requirements, authorizations, and generally all acts of authority which originated under the Electrical Supply Regulations, 1927, or any regulations issued prior thereto, and are subsisting or in force on the coming into force of these regulations, shall take effect for the purposes of these regulations as fully and effectively as if they had originated under the corresponding provisions of these regulations, and shall, where necessary, be deemed to have so originated.

12–12. All actions, prosecutions, and other legal proceedings commenced under the Electrical Supply Regulations, 1927, and pending or in progress on the coming into force of these regulations may be continued, completed, and enforced either under the Electrical Supply Regulations, 1927, as if the same had not been revoked or under these regulations.

12–13. (1) In any case where the Chief Electrical Engineer, upon application being made to him in writing by the person intending to erect or construct or alter any electric line or work, is satisfied that strict compliance with these regulations would involve expenditure out of proportion to the degree of freedom from electrical hazard to be secured by such compliance he may modify such requirements if satisfied that reasonable freedom from electrical hazard can otherwise be secured.
(2) Every such application shall be accompanied by a full statement of the reasons why such modification is desired and of the nature thereof.
