I'm afraid I have to ask the knowlegable folk here to cover the familiar topic of outside electrics.
I have searched on sheds outside ect already
I have noted BAS's comments
I have considered part P
I considered burying the cable to the right depth
I considered the voltage drop
I have local electricians quote which is very high
I will apply for PP and get an electrician to assist
I promise I won't turn anything on until someone qualified tells me to!
however I still have a question,
I wish to supply power to an outside shed taking a spur from an inside socket which is part of the 13A ring main.
The shed is 12M from the socket and inside the shed I will have a dedicated shed CU with 35amp and 6amp circuits with RCD's, supplying a couple of sockets and a flourescent light. I rarely expect the load to exceed 2000W. Odd drills soldering iron etc.
Between the shed and the house I will use 12m of 2.5mm 3c SWA, cleated and running along the bottom of a brick wall.
However whilst I'm happy at the shed end, I'm not sure what to do at the house end. I've got a ip55 spur unit with RCD and it's rated at 13 AMPS.
I could mount this on the outside wall which would be opposite the intenal socket and use 12 inches of 2.5m twin to feed the spur.
I reckon that this would suffice in power terms, however the wife would like a pond pump and external low voltage lights and I could see the load climbing if I wasn't really careful, or if I needed to run a heater in the winter.
So my question is about the most legal and efficient way to get the maximum power from the ring main socket to the SWA cable.
Could I replace the 13amp external spur with a 20A CU with RCD (maybe even the same type of shed CU I have at the shed end) in an IP55 box for example? I believe the loading would be accepted by the wiring but maybe not by regulations?
My house CU does not have any RCD which is why I need to begin the external wiring with a RCD unit. (so I am told)
The easiest thing of course would be wired to the MAIN CU in the house but that is not possible, as the shed is an after thought following major internal redecoration and the CU is central in the house.
Any thoughts or guidance would me most apprciated.
thanks
Paul.
