I had to disconnect a fuseboard and fit a temp with 2no TSO's, RCD protected, The earth was poor condition TNS so I advised the house owner have a PME done before the old board was reconnected as there is no RCD protection to the old board, when the PME was fitted a new 100 amp fuse was installed but the old fuseboard main switch has a 60 amp rating, is this a code 1 on the periodic and should they come back out and change the fuse back to a 60 ?
TIA
