Just carrying out an EICR on a farm (!!) with a number of DBs spread in a fashion more similar to a hand grenade then any logical approach.
This one took my interest the most as from the supplying DB (3PN) the installer has run a 3C SWA from two separate C curve 32A 60898 MCBs. Earthing is TT. This runs into an old 17th RCCB board.
Its not a split load board.
They then have one phase running to a 2mod 32A RCBO which supplies an adjacent building and the other phase to an RCCB which supplies the local equipment within that building.
Lots of thoughts on this but just wondering if others views on this, particularly RCCB/RCBO compatibility when reporting findings......🤔
