[QUOTE="denmancentral, post: 542342, member: 36023"] kA rating is not relevant to the tripping, that's the maximum short circuit current the MCB can handle. 8000W is about 33A so although the MCB shouldn't immediately trip unless the current is much higher, it is undersized. I would ask the electrician to run the correct diameter cable and supply a new 50A MCB. They will want to know the inverter specs and cable length plus how the cable is run (clipped direct, in insulation etc). [/QUOTE]
