I have bought a new build house. which has a split load twin RCD CU.
As expected, each bank has a socket circuit (not labelled Up or Down).
Isolating one circuit turns off half of upstairs and half off downstairs and the other MCB in the CU isolates the other half.
while a decent spark should isolate and prove dead before work, Joe Bloggs maybe tempted to crack on thinking he has isolated the upper ring not realising that only half is dead.
Thoughts anyone????
