Use of ECBs

[AlanBeckett]

I take a pessimistiv view and stuff the Regs. The Garden/Garage/Aviary/Greenhouse etc are fed by a 30A Breaker in the main Consumer Unit. The Cable down the Garden is 4-Core SWA with two Cores and the Armour Earthed. I tried putting an RCD in the way but it tripped regularly due, I suspect, to leaks and Phase Shifts. So I took it out and now each area has its own small Consumer Unit and 30mA RCD. Despite being PMEd the 'Outside Circuits' are undoubtedly 'Earthed' via my big Aluminium Greenhouse, which has multiple Earth connections via another section of SWA from the Garage.
I'm not having any problems and I'm still here.
