I'm hoping some of you guys out there on the forum can perhaps provide the benefit of your experience with the below issue:-
Currently working on a job where the garage which is approximately 25 - 30 feet away and adjacent to the house, has its power fed to it via SWA connected off the back of a 13amp double socket in the utility room. The house is a new build built in 2010 and this was installed by the builders. The owners have requested to have additional circuits installed in the garage for which an upgrade to the existing DB will be required, however be fore I get into that I wanted to ask some advice.
The SWA is terminated within the garage to a 2-way DB, protected via a double pole 30mA RCD with 2 MCB's of 6A & 16A respectively. Obviously the cables and circuits within the garage are protected by the RCD in the DB, however my concern is the SWA cable is coming off the final Ring circuit [from the socket in the utility room] and this / is not protected by RCD other than the main RCD in the main CCU via the final ring ciruit, so any fault in the SWA will cause potential probelms not just with the cable itself, but potentially with the RCD in the main CCU and that of the final ring it is fed from, not to mention possible issues with the power in the garage.
To get round this I was wondering whether one of the following options might be a better approach
Any ideas / thoughts will be greatly received.
Many thanks

To get round this I was wondering whether one of the following options might be a better approach
- Connect the SWA to a seperate FSU so as to provide a level protection if a fault occured in the cable
- Or use an FSU that has inbuilt RCD protection, but I'm not certain an FSU of this type is available as I have never come across one
- Run the circuit directly back to the CCU, however this will pose a real headache as there is no easy route, if any, to the CCU at the front of the property
- Leave it and do nothing and hope that the SWA cable is never compromised, ending up in further faults occuring
Any ideas / thoughts will be greatly received.
