2.5 is chased in...
Reason for rcbo is so it doesn't interfere with house.
this garage supply is already in right place to hook to shed, getting armoured from cu is a bit of a nightmare hence not going mcb non protected etc.
Was saving cost by not going for another board and stake ... Ideally. Rcd would be in shed For localised tripping but wanted to use existing feed near by but that cable needs protecting hence needing it fed from rcbo.
Hope that make sense. Lol
Sounds good
