    Extending the equipotential Zone of PME installation.

    I was going to just add on to Voltz's thread but it seemed to come to a natural end but I had some questions. 1. A few experienced members say that you should not extend the (equipotential zone) EPZ of a PME system. Am I right in thinking that this is because of the possible potential between...

    Hey pepes. I'm a bit new to Ryefield boards, so maybe an obvious one. While installing the Ryefield boards in the risers to feed the flats in a tower block (40 floors), we were told to remove the PME links from within the boards. Should there only be a link at the supply, as it is a PME system...
