What is BS 4363 - Electricity supplies for construction and building sites about?
BS 4363 specifies the requirements for distribution assemblies for the control and distribution of electricity from a three-phase reduced low voltage a.c. the system at declared voltage up to 110 V (63.5 V to earth) or a single-phase system at declared voltage up to 110 V (55 V to earth), for use for the protection and control of electricity supplies on construction and building sites in the UK.
Who is BS 4363 - Electricity supplies for construction and building sites for?
BS 4363 on electricity supplies for construction and building sites is useful for:
- Electricity suppliers
- Testers of electricity
- Regulatory authorities
- Construction industries
- Contractors
- Builders
Why should you use BS 4363 - Electricity supplies for construction and building sites?
A site is an area where any of the following works are undertaken/executed: new building construction, repair, alteration, extension, or demolition of existing buildings or parts of buildings, engineering construction, earthworks and works similar to those listed in items.
BS 4363 specifies a typical schematic layout indicating this will help you to the assemblies that are interconnected to give a single-phase reduced low voltage (RLV) supply, and BS 4363 specifies the layout when both single-phase and three-phase RLV supplies are required. BS 4363 also specifies typical system voltages at mains frequency (50 Hz) employed on construction and building sites.
Overall, BS 4363 provides you with the essential requirements for the various types of distribution assemblies for reduced low voltage systems intended for use on construction and building sites.
