1 ELECTRICAL INSTALLATION DESIGN Three Day Course with option to achieve BTEC Advanced Award INTRODUCTION This course is aimed at the needs of designers, specifiers and others involved in the design and specification of low voltage electrical installations. OBJECTIVES To introduce participants to the requirements of BS 7671: 2008 (the IEE Wiring Regulations, Seventeenth Edition); To explain how the Regulations are intended to be applied in practice, with the emphasis on design and specification. BTEC Advanced Award Engineers new to the Building Services industry and Electricians, especially the selfemployed or those working towards self-employment, will find this optional Level 3 Award particularly advantageous. The Award involves 40 hours of self-study (with learner support) over six weeks. You will need to demonstrate your understanding of BS 7671 to produce a functional design solution for an electrical installation encompassing the following requirements: Isolation and switching; Special installations or locations; Inspection, testing and certification; Protection against overcurrent; Shock protection and earthing and bonding; Selection and erection of equipment. An additional fee is payable for registration with the awarding body.

2 SYNOPSIS OF COURSE CONTENT PRE-COURSE READING: 1. Introduction to BS 7671: 2008 Background; Structure and numbering system of BS 7671, and using the Standard; Important terms used in BS 7671, and their definitions. 2. Requirements of BS 7671 for Isolation and Switching facilities. MODULE 1: INTRODUCTION TO DESIGN The legal background, parties involved, procedure and documentation. MODULE 2: ASSESSMENT OF GENERAL CHARACTERISTICS The purpose of the Part 3 Assessment, and the necessity for determining all the relevant parameters for an installation. MODULE 3: OVERCURRENT PROTECTION - PRINCIPLES The principles for protection against overload current and fault current. MODULE 4: SELECTION AND SIZING OF CONDUCTORS AND CABLES 1. Factors to be considered in the selection of wiring systems; 2. Detailed requirements for live conductors and cables; 3. Application of the overcurrent principles of Module 3, and various constraints including voltage drop, to the sizing of live conductors; 4. Techniques for economic sizing of grouped circuit live conductors, where specified conditions are fulfilled. Note: Circuit protective conductors will be covered in Module 5.

3 MODULE 5: SHOCK PROTECTION, EARTHING AND BONDING 1. The requirements of BS 7671 for isolation and switching facilities; 2. Ways of meeting the requirements, including suitable devices that may be employed. MODULE 6: ISOLATION AND SWITCHING 1. Ways of meeting the requirements, including suitable devices that may be employed. MODULE 7: PROTECTION AGAINST THERMAL EFFECTS. ETC 1. Protection against thermal effects and precautions where risks of fire exist; 2. Protection against overvoltage and undervoltage; 3. Requirements for supplies for safety services. MODULE 8: SELECTION AND ERECTION OF EQUIPMENT The requirements of BS 7671 relating to the selection and erection of equipment. MODULE 9: SPECIAL INSTALLATIONS OR LOCATIONS 1. What makes the Installations and Locations of Part 7 special ; 2. When and how Part 7 is employed; 3. Examination of particular requirements for each locations.

4 MODULE 10: SUMMARY OF INSPECTION AND TESTING REQUIREMENTS 1. BS 7671 requirements for initial verification; 2. Information and test data to be provided to the inspector/tester; 3. Design certification on completion. DESIGN EXERCISE An opportunity to apply many of the most important design requirements and constraints of BS NOTE: The participants notes include additional material for self-study after the course, and an Appendix on Design Documentation.
