Many lighting professionals, those new to lighting, those not from an electrical background, or those with an electrical background that may need to be updated on the latest version of the wiring regulations (BS7671) will find this webinar invaluable. Much has changed recently, with many Distribution Network Operators only making TT connection; the customer needs to make their own earthing arrangements. This change has impacts on the earthing arrangements for all other electrical street furniture within 2.5metres to ensure public safety. There are requirements now for surge protection and with different types of devices available, do they need to be supplied and if so what type? This webinar gives valuable information on these issues and many more as they affect exterior lighting installations. This webinar coincides with the launch of the ILP online training course ‘Fundamental Lighting Electrical’, being an update to the one-day course previously held in Rugby. The course is available from the ILP online training platform, with discounts for ILP members and is essential to keep you abreast of current thinking.

13. Some questions that you will be able to answer
once you have completed this course
 In an electrical circuit what is a Surge Protection Device (SPD) and what does it do?
 List the for three main types of earthing systems used in street lighting and how would
you identify these?. N.B. Earthing systems will have a series of letters ‘N’, ‘C’, ‘T’, ‘S’
 What are all the different types of electrical cables and what type of B.A.S.E.C.
approved cable would we use when installing underground cables ?
 How would you carry out a simple cable calculation to determine the fuse size to protect
the circuit on an exterior lighting installation?
 How would you identify a low voltage overhead line.
