I'm stripping apart my house during renovation, part of which I have found an FCU in my dining room, the supply to this FCU is from my downstairs mains ring circuit, the load is a heavy duty armoured cable that runs through the wall and outside the house travelling approximately 20m to my garage, where it's connected to a sub/mini CU.
I'm wondering if this is safe and whether this supply should have it's own segmented supply direct from the house CU with its own flip-switch?
It's also worth adding that the garage has virtually zero electricity consumption, its really only to power the lights and the occasional power tool etc, but very rarely.
If it is indeed a safe way to route outdoor power, would it be safe to break into the cable at a sensible point on the exterior of the house, and add some outdoor proof suitable rated plug sockets?
My house CU is RCD protected.
