Yes that's correct. If there is no RCD protection then a line to earth fault such as mechanical damage to the SWA will not automatically disconnect the circuit, and that's a bad thing™

It's more common to use switchfuse(s).remove SWAs and relocate them externally into a mini IP rated CU and enclosure, swa protected with mcbs,
Hope there are no metallic enclosures fed by unprotected tails.

As long as you've got sufficient discrimination between the device the one(s) in the outbuildings. A good reason to use switchfuses.Im just trying to think of a fault that would trip the OCPD and would need someone to access the cupboard and all i can think of is if the SWA got cut!
Hopefully your electrician will have the gumption to use metal enclosures.The only point maybe that the SWAs need to be installed into adaptable boxs to extend them to the new CU.

Fair enough, but it's your electrician who will be deciding what to use, not you or I.I dont think theres room for 3 switch fuses and i cant see the advantage.
Fair enough, but it's your electrician who will be deciding what MCB ratings to use, not you or I.I would also assume he would use the same size as the current MCBs, as these have always seemed to work ok and never tripped.
Fair enough, but it's your electrician who will be terminating the SWA, not you or I.Also, i cant see the advantage of using metal enclonsures? As long as the SWA is earthed, i dont see a problem with using either.
