I have not posted anything in the 2 1/2 years I have enjoyed this forum and that is in the main that I should not really be here because I am not now a UK electrician, having been living and working in Southern Spain for the last 12 years. However I could not help myself and wanted to see what life for you guys was like back in the UK. I work here to a slightly different set of regs and installations to the UK, the two main ones being that RCD's are mandatory on all circuits on all installations and more than half of domestic installations are three phase. Also, due to the failures of the supply network all new installs must have both transitory and permanent overvoltage protection. I do notice however that you guys are gradually having to change to met our European norms.
