Hi All
Working on a scheme whereby we have a private transformer serving the site - TN-S arrangement. This comes into the building, we then split to feed a switchboard in one part of the building which is existing, the second split heads to a new build part which has the second switchboard. This new build contains swimming pool. The supply to the new switchboard is via a busbar 3L+N+PER. Question relating to earth bars - we currently have the main earthing bar at the intake point which is at the existing switchboard location - we then had cable feeding out to the new earth bar at the new switchboard location. Contractor is proposing that they remove this interlinking earth cable between bars, and take a bond directly from the new switchboard earth bar to the new earth bar in the room. Does this sound feasible - to me doesnt sound right, but I can't find anything specific to say not.
Many thanks
