[QUOTE="Sidney, post: 462922, member: 30039"] I would bond the utilities as normal within each property and also the building fabric. Basically bringing the whole property to the same potential. Under fault conditions there is the potential for the whole system to become live however with the size of the building and it's construction tied in with lightning protection the touch voltages would be minimal for a very short duration. Not forgetting nearly everything will normally be put on some form of RCD. As for the LP, as long as the building services have surge protection at each point of entry then I can't see any issues. Also I would consider adding SP to each flat DB to create their own zones within the building. [/QUOTE]
