I'm speccing up installing sockets in a brick garage. It currently has a
CU
with an adjacent pair of double sockets on a short radial. I want to put
some
sockets at various points around the far sides.

Because of the construction of the garage, it would be easiest to run the
wiring at head height, and run down trunking to the places where sockets
are
wanted. There are roughly two options:

1. A radial around three sides, with the sockets on essentially long loops
down from the ceiling. This is just an extension of the existing radial.

2. A ring main around at ceiling level. The simplest way would be for
each
socket to be spurred off, but I understand spurs aren't well received. An
alternative would be to use a variation of 1) where the ring takes a long
loop down to each socket


The natural way to do this would seem to be a ring with spurs, but if
spurs
aren't recommended then a ring or radial with loops would seem a sensible
option. In that case, would it be sensible to have a long run of cable at
ceiling level, with a pair of junction boxes for each socket downlead, ie:

-----+ +----
| |
| |
socket

where + is a junction box?

Also, Part P wise, am I right in thinking that extending a radial is OK
but
converting a radial to a ring is notifiable?

Finally, is it acceptable to cable-clip T&E cables (bearing in mind the
new
rule to use metal clips occasionally) in an outbuilding, or is additional
protection (trunking) needed (even at ceiling level)?

Thanks
