Hello all.
I have been asked to fit a Ryefield board and switch-fuse on an existing 3 phase supply so that a shop can have its own meter and 3 additional meters are going to be installed for future flats above the shop.
All of these are currently on 60a switch fuses.
Have spoken to UKPN and they are only down to upgrade the existing fuses to 100amp, the connection of the Ryefield and meters is to be carried out by Seimens.
I have only fitted really Ryefields on new installs where UKPN have specified the switch fuse size / tails earth etc.
They have sent me the surveyors notes who only mentions about installing redheads in the Ryefield.
I was thinking 35mm tails to the Ryefield via 125a Isolator and then tails out of there for the 4 meters.
