Hi and new to the forum and looking for some advice.
I have a prefab office (posh shed) 10' x 8' being delivered and I'm looking at options for putting electrics in. (due to Part P, I'll need professional help but I would like to understand what I'll need.)
The building will be about 20m away (as the cable would run) and I have assumed that I would have a single supply to the shed and then have it broken out into a small ring main and a lighting main. So the theory goes like this:
From the main house consumer unit I would look to have a smaller unit, see:-
Volex Shower Unit 63A 30mA RCD 1x50A MCB
Link
From this unit I expect to run outside, down to the shed and into one of these
Volex IP55 Garage Unit 40A 30mA +1X6A 1X16A SP MCB
Link
But the temptation is to change the 1x16A for a 1x20A. (or should 16A be enough)
The shed will have a few PC's (4 x double 13A sockets) plus a 2KW oil heater.
The internal lighting will be a 1.5mm and mains would be 2.5mm
Is my thinking on the right lines ?
What sort of cabling would be required from the existing consumer unit to the "shower unit" and then what would be the best option for cabling running down to the shed? I have been looking at standard 25 or 40mm plastic condiut (underground not possible all the way) (condiut cable, armoured etc, size 4mm, 6mm )
Thanks in advance.
