  • Installations are required to be of proper construction;
  • Conductors must be insulated or other precautions taken;
  • There must be means of cutting off the power and means for electrical isolation.
  • The hardware requirements are complemented by a group ofRegulations stating principles of safe working practice.
  • Regulation 14, which covers live working, is of particular importance.
• Electricity Safety, Quality and Continuity Regulations (ESQCR)


  Regulations that specify power quality and supply continuity requirements to ensure an efficient and economic electricity supply service for consumers, and safety standards to protect the general public and consumers from danger
• Statutory

  The Guidance is targeted primarily at duty holders identified in the:

  • Regulations

• The requirements of the ESQCR apply to public and private operators and to electricity networks used to supply consumers in England, Wales and Scotland
• Construction Design and Management (2007): Statutory

  • Improve health and safety in your industry, have the right people for the right job at the right time to manage the risks on site, focus on effective planning and manage the risk - not the paperwork.
  • Everyone controlling site work has health and safety responsibilities.
  • Checking that working conditions are healthy and safe before work begins, and ensuring that the proposed work is not going to put others at risk, require planning and organisation. This applies whatever the size of the site.
• BS 7671(2018 + A3 2022)

  The IET Wiring Regulations, currently in its 18th Edition. A no-statutory document
• BS 7671(2018 + A3 2022)

  • It is a non-statutory document
  • It is a detailed, technical document, if complied with, will lead to compliance with statutory documents, such as the Electricity at Work Regulations 1989
  • This document may be used in a court of law in evidence to claim compliance of non-compliance with a statutory requirement
• • BS 7671 frequently changes
  • These changes are called amendments, reasons for the frequent changes is that technology constantly changes
  • With new technology, the methods of regulations need to be changed to ensure that new practices and methods remain safe
• What are Amendments

  The change of how something is done
• Why bring The On-Site Guideon site

  • For essential quick-reference guide to BS7671:2018
  • Its designed to be taken on-site for easy referencing and provide simple guidance on the application of BS7671
  • All updates in Amendment 3 will be included in the on-site guide
• Why use an The On-Site Guide

  
  

  • Its intended to enable the competent electrician to deal with small installations up to 100 A, 3-phase
  • It includes simple circuit calculations and provides essential information in a convenient, easy-to use form, avoiding the need for detailed calculations
  • In essence it is an abridged version of BS7671:2018 with all the necessary information without the complicate jargon
• The lET guidance notes are to expand upon and simplify the requirements of BS 7671:2018

  • Guidance Note 1: Selection & Erection
  • Guidance Note 2: Isolation & Switching
  • Guidance Note 3: Inspection & Testing
  • Guidance Note 4: Protection Against Fire
  • Guidance Note 5: Protection Against Electric Shock
  • Guidance Note 6: Protection Against Overcurrent
  • Guidance Note 7: Special Locations
  • Guidance Note 8: Earthing and Bonding
• • Building regulations set standards for the design and construction of buildings to ensure the safety and health for people in or about those buildings.
  • They also include requirements to ensure that fuel and power is conserved and facilities are provided for people, including those with disabilities, to access and move around inside buildings.
  • If you do not follow the building control procedures set out for handling your building work or you carry out building work which does not comply with the requirements contained in the building regulations, you will have contravened the regulations.
