I mentioned in a previous post that a 40a mcb ran to a 13a fcu providing power to my loft - i have also just noticed a 32a mcb running to garage (not connected) would it be advisable to swap the mcb's over so the loft runs from 32a (to a fcu powering 2 double sockets + fcu with 3a for lights)
and use the 40a to garage installing a 2 way unit with rcd
