Evening all, I'm just after some clarification on what set up is best/required by the regs..
TT system , cable comes into the house into the cut out , tails into the meter and then out of the meter into the DB.
Currently a small board with RCBOS doing lights and power and then a 40amp MCB feeding a RCBO in an enclosure just below the DB which supplies a SWA that feeds an external garage DB with a 30ma RCD main switch.
At the moment when something trips in the garage it trips the RCBO in the house as there is no discrimination between the RCD and the RCBO, whats the best set needed here?
Cheers
