garage and shed power supply

[gregorabbott]

hi folks, you have probably been asked this many times but any ideas the best way to avoid nuisance tripping? i am running power to a garage using 10 mm swa, the garage is about 25m away from the main fuseboard which is a wylex all rcbo's with 1 spare way. i am then taking power to a shed from the garage using 6mm swa. the shed is about 20m away from garage. the swa will be buried underground. best way to avoid nuisance tripping?

MCB at house for sub main (providing its all armoured) Then at the garage have an RCD for the garage final circuits and an MCB again for the shed sub main, then at the shed have an RCD for those final circuits. Basic stuff just keep all the non-rcd protected cables as armoured is the easiest way to comply with the regs

Exactly, not a rocket since there.

ups, sorry,too slow me, Eng54 already pointed that out
