Amendment 1 of BS 7671:2008 17th Edition Wiring Regulations now includes a key new section (534) for protection against transient overvoltages using surge protection devices (SPD’s).

Overvoltages from atmospheric origin (lightning) or electrical switching events can severely effect electrical installations and connected equipment.

The risks to life, buildings and electronics due to overvoltages are detailed within BS EN 62305 ‘Protection against lightning’ and can be reduced through the correct selection and installation of SPD’s in accordance with Section 534.

The new regulations where published on the 1 July 2011 and came into effect on the 1 January 2012. This means that all installation designs must now comply with amendment 1.
