Dear Treggers, I was forwarded the protective earth question written by Alan Booth, and this is my reply. The earthed SELV circuit always has a connection to protective earth, and, due to the relative short circuit this provides, all the current present would immediately flow to earth. The test associated with this clause is the earth continuity test of clause 2.5.11, where the resistance of the connection between the protective earthing terminal and parts that are required to be earthed shall not be more than 0.1 ohms. I hope your misery is now lessened, and you will be able to sleep again :-) Best regards Dave Whelan Safety Engineer TUV Product Service 12 Marshall Road Hillmead Swindon Wiltshire United Kingdom SN4 9FZ TEL +44 (0)1793 871 990 FAX +44 (0)1793 872 990 http://www.tuvps.co.uk
