As a result of many years developing and teaching courses devoted to compliance with the IEE Wiring Regulations for low voltage installations up to 750V & IEC 60364 as well, it has become apparent to me that many operatives and personnel in the electrical contracting industry have forgotten the basic principles and concepts upon which electric power supply and its use are based. As a result of this, misconceived ideas and much confusion have arisen over the interpretation of the regulations. It is the intention of this course to dispel such misconceptions and to educate and where necessary refresh the memory of the trainee. In this respect, emphasis has been placed on those areas where most confusion arises, namely earthing and bonding, protection, and circuit design.

By the end of this course delegates will be able to:

• The latest requirements of the IEE Regulations and the required Electrical Design concepts
• Working within an environment controlled by IEE Regulations
• The basis for safety and functional design
• Inspection and testing techniques that affect the maintenance routine of an installation
