適用范圍：This British Standard gives recommendations for the management, design,setting-up and operation of temporary electrical systems using low voltage a.c.electricity, for the entertainment and similar or related industries. Mobile andtransportable units with electrical installations that are used in these industriesare also covered.This British Standard gives recommendations for the provision of a safe andsuitable temporary electrical system for an event and the duties and work toimplement this.NOTE 1 Each aspect of the work could be under the control of a different personresponsible.This British Standard gives guidance on matters of common interest toproducers, production companies, event organizers and managers, freelancepeople, facilities and services hire companies, equipment hire companies,equipment manufacturers, electrical consultants, electrical installationcontractors, distributors, suppliers of electricity, venues, local authorities andthose responsible for safety.The systems covered by this British Standard operate at low voltage as definedin BS 7671:2008+A1:2011 and supply equipment normally operating at 230 V a.c.or 400 V a.c. 50 Hz. Electricity at low voltage can be taken from an existinginstalled electrical system, the public supply, privately owned supplies or frommobile or portable generators. Direct current supplies are outside the scope ofthis British Standard.NOTE 2 It is expected that all electrical equipment, switchgear units, distributionunits and cables used for work covered by this British Standard are manufactured tothe appropriate product standards, and that the temporary electrical systems andtheir use are designed, set-up, supervised, operated and removed by suitablycompetent persons. It is also expected that responsibility for such temporaryelectrical systems is taken by a suitably competent person referred to as the personresponsible.NOTE 3 All equipment forming the temporary electrical system is expected to bedelivered to site as pre-assembled units that have been tested and are known to besafe and suitable for use. This does not preclude the manufacture on site of simpleunits that might be necessary; though this is the exception and not the rule.NOTE 4 In many situations temporary electrical distributions are intimatelyassociated with mobile and transportable units. In such cases, seeBS 7671:2008+A1:2011, Section 717, for further information.NOTE 5 This British Standard may be applied to temporary electrical distributions atexhibitions and fairgrounds; see BS 7671:2008+A1:2011,Sections 711 and 740, respectively for specific information for these activities.Specialized documents related to exhibitions are published by the Association ofEvent Venues [1].NOTE 6 Specialized documents related to theatres and places of entertainment arepublished by the Association of British Theatre Technicians [2].NOTE 7 This British Standard does not offer guidance for hazardous locationswhere expert advice needs to be sought.
