Add Extra Double Socket in Shed

[adzyp]

Morning all,

I have a 6x8 shed which has already been hooked up with electrics. Currently has one double socket and a light switch by the door, but im looking to get an extra socket put in at the other end of the shed as I need to put a temporary chest freezer in.

Is it possible to spur off this existing socket with it only having one wire going into it which usually suggests this is a spurred one in itself? Is it different in this shed setup than inside the house?

Its likely a radial circuit, can you confirm that the breaker in that board on the right of the picture that feeds the sockets is 16A (looks like it, but the picture has glare/reflections on it)?

A radial circuit may be extended to feed any number of sockets

It says B16

Yeah the socket breaker is a B16

So yes, you can add a second socket.. use 2.5mm² T&E cable to make the connections.

Any issue using 10mm round T&E? Got plenty lying around.

That is not 10mm²! The 10mm refers to the cross-sectional area of the copper conductors, not the physical diameter of the cable sheat.
It MAY be big enough, but your picture gives no indication of scale. is there any information stamped on the sheath?

Oops, sorry dumb moment there. Diameter of the copper strands per core is 1.5mm. So if my calculations are correct, this cable is spot on?

0.75 x 0.75 x 3.142 = 1.77 per core x 2 cores = 2.5ish

Or do i factor in earth too, in which case its around 5mm

 

[EFLImpudence]

You only count each core size - so, likely it is 1.5mm².

 

[Taylortwocities]

Yes, that would square with the overall diameter, if you see what I mean.
16A is right on the edge for 1.5mm² cable. You can get a cut 10meters length of 2.5mm² T&E from Screwfarce, Tuillestation and the sheds for under a tenner.
The rest of the circuit is wired in 2.5mm² T&E, so you should cable the rest the same. Why not do the job properly?

Yeah absolutely, just had this stuff lying round and it looked the same thickness, but I guess the difference between the 2 is hardly visible to the eye. Just been and got the proper stuff
