i work in an old hotel with crabtree c50 breakers which we cant get any more and were having a new combi over fitted which requires 63 amp rcd to protect it which is 3 phase what size breaker would you recommend to put before the rcd as we only have a 60 amp also we have a deadman switch controlling the board as theses older boards have no main breaker is it possible to run a smaller new board from this to place the rcd in as well as the main board thanks for any advice or help
