1 Scope
NOTE 1 Each aspect of the work could be under the control of a different person responsible.
NOTE 2 All equipment forming the temporary electrical system is expected to be delivered to site as pre‑assembled units that have been tested and are known to be safe and suitable for use. This does not preclude the manufacture on site of simple units that might be necessary; though this is the exception and not the rule.
NOTE 3 It is expected that all electrical equipment, switchgear units, distribution units and cables used for work covered by this British Standard are manufactured to the appropriate product standards [e.g. BS EN 61439 (all parts)], and that the temporary electrical systems and their use are designed, set-up, supervised, operated and removed by suitably competent persons. It is also expected that responsibility for such temporary electrical systems is taken by a suitably competent person (referred to as the person responsible in this British Standard).
NOTE 4 In many situations temporary electrical distributions are intimately associated with mobile and transportable units. In such cases, see BS 7671:2018+A2:2022 and in particular Section 717, for further information.
NOTE 5 This British Standard can be applied to temporary electrical distributions at exhibitions and fairgrounds; see BS 7671:2018+A2:2022 and, in particular, Sections 711 and 740 respectively for specific information for these activities. Specialized documents related to exhibitions are published by the Association of EventVenues [1].
NOTE 6 Specialized documents related to theatres and places of entertainment are published by the Association of British Theatre Technicians [2].
NOTE 7 This British Standard does not offer guidance for hazardous locations where expert advice needs to be sought.
