The SY2-D surge protector (SPD)

Surge protection made easy for 18th Edition! Also available in (sober) article form at: https://www.dses.co.uk/index.php/free... Device kindly supplied to me by Surge Protection Devices Ltd. following my approach to them after seeing their stand at Elex 2018. This is not a paid promotion. Note that the graphic showing the connection of this device around the 14 minute mark is technically incorrect - it should show the main switch connected to the top of the RCD, then the MCB connected to the bottom. A corrected graphic can be seen on my website.
