[QUOTE="green-hornet, post: 69604, member: 2683"] We have had this problem before, so much so that there have been various research in to the failure rates of RCD's. The last one proved that under proper use and regular testing they performed very good with something like 98% success. However as we all know in the real world, people do not carry out the regular quaterly checks. Buiding works where excessive dust has entered the CU, has prevented some RCD's to function correctly, and because it is a mechanical it needs regular movement to prevent any stifffy, sticky actions. I must admit I was a great fan of bonding, and I did take great pride in doing a good job, with pig tails an all, frowned upon now for giving undue stress on the cable? It makes you wonder don't it?
