I'm planning on building myself a large shed at the bottom of the garden. I
need to understand how I provide an electricity supply within regs.
I've broken my query down in to a few categories. I've check on the FAQ and
googled previous posts and not found quite what I'm after. I guess I'm
after some expert reassurance that I'm thinking along the right lines too.
My consumer unit is to the front of my house, and I've just got a new
driveway - so I need to avoid any digging to the side of the house, meaning
a section of the run will be internal, the rest will be 3 core SWA.
I have a few options here, and I need to understand which is best..
a) Use existing RCD in consumer unit, put some breakers in shed
b) Install new RCD inside house via 30a breaker in existing consumer unit,
again breakers in shed
c) RCD and small consumer unit in shed with connection to a 30a breaker in
existing consumer unit
As I need to run a section inside the house, I need to understand a) if this
is OK, or whether the SWA should run all the way to the fuse board, and b)
what cable size (as I want 30a supply over 30m I understand 6mm T&E is
Assuming I can do this, then can I run the T&E in to one of these
mounted on the outside wall
to meet the SWA? Can I add a spur with an external socket at this point?
Where the SWA leaves the house I understand it needs to be protected.
What's the best way to do this?
I also understand that the depth at which the cable is run is fairly
discresionary. I'm thinking 20-30cm under the patio (patio yet to be laid),
then 50cm under the lawn.
I've not done any electrical work since December 03, so I've no experience
with the new Part P regs. What testing and paperwork do I need to get done
so it's all legit? Are there any indicative/ball park costs?
Many thanks for your help...
