    Crabtree RCCB 80A 30mA

    Correct wiring of RCCB?

    Hello all.. I figure its better to ask and be ridiculed than not! I am about to add a couple of spurs to a ring that is not RCD protected. The neighbour definitely wants them channeled in rather than surface trunking so I have to RCD protect. It is an old Tenby CU with crabtree SB6000 MCB's. I...

    Hi all, To keep it short and to the point, my neighbour has a PV array on a shed which goes to an inverter, then to a 20A RCBO (I think) in a small CU and then back to the main CU in the house where it goes to a Hager 40A RCCB (30mA). The 40A Hager in the house trips periodically for no reason...
