Funny you should bring this up. I have been in my house for two
years and from the start I was aware that my garage, a brick built
one, attached to the front of the house, is fed from the upper ring.
I wasn't too concerned until I went to add a double socket into a bed
room, when I took off an existing socket and found three cables into
it. Obviously two for the ring, and whats the other for????? Oh -
its a spur to the garage! I assumed the garage would have been part
of the ring itself, but no - its just a spur. I have fitted a heater
and lights in the garage, so I think I'll put a fused spur in the
bedroom to be on the safe side before bigger and better adjustments
are made.
Mine been just like that for 22 years. My garage is 4m from house.
The spur feeding it comes off the back of a bedroom socket for some reason.
then runs down the cavity, out the wall 25cm above the path, goes under
concrete path in what looks like black hosepipe and reappears inside garage.
All in 2.5mm cable!
Seems to work ok, maybe some day I'll get around to replacing it... :-)

om...
We have just moved onto a brand new house built by a large building
company, I installed some security lighting around the garage at the
weekend, went to turn off the Garage supply to make the final
connections, checked the Consumer unit, no mcb for the garage,
checked the room where the supply enters the house, no switch there
either.
Found I had to turn off the ground floor sockets to isolate the
supply.
Now I have been out of sparkying for about 6 years, so am a little
rusty on regs now (trained on 15th ed).

As far as I can make out the supply is spured off a socket in the
Utility room (socket placed about 6 inches left of the sink), this
goes to an outside platic box, converts to swa, at the garage, swa -
plastic box - back to t+e to fused spur for the light and then double
socket.

Am I right in thinking the following is wrong

1. Socket too close to sink for one, there is a better position
available
2. Spuring off the socket with no local isolation for the garage
supply?
3. Isn't there something about equipitential zones when the remote
building is not connected to the house.

I was thinking if there is a problem in the garage or with swa cable,
the RCD would trip taking out the whole of the house sockets, no
doubt the little platic boxes will be full with water in no time.
The
missus is bound to be on her own when this happens....

In time I'll proably rip the whole lot out and take a supply direct
from the consumer unit on its own rcd. Oh by the way the consumer
unit is only 2m from the socket the supply is spured from
And to think some of the houses that do not have garage supplies as
standard, they charge £375 for this
