Abstract
DEVELOPMENTS in electric discharge lamps and the very rapid increase in their application have produced an urgent requirement for the revision of Section 8 of the Regulations for the Electrical Equipment of Buildings issued by the Institution of Electrical Engineers. A new edition, the twelfth, of the Regulations is at present in preparation ; but to meet this immediate need Revised Section 8, "The Installing of Electric Discharge Lamps", has been produced and supersedes, as from July 1, the corresponding section of the eleventh edition. Fluorescent tubes operating at normal mains voltage become, for the first time, a subject of specific requirements under Section 8A, which covers all discharge lamp installations in which the open-circuit voltage does not exceed 650 volts. Section 8B gives additional requirements for high-voltage installations up to 5,000 volts to earth, which is the maximum voltage permissible.
