What type of consumer box

[stevenson166]

Hello All, First of all i am not an Electrician just a DIY enthusiast.
I have just built a garden bar shed and have the following in place. Please see images.
Consumer box in the garage fed by the main house supply. Pic shed 5 and shed 6

this then exits the garage by a fused switch

This feed then enters the bar shed and terminates

My question is that i am NOT going to attempt to do this myself, All i want to do is advice on what consumer unit i need to buy so that i can keep costs down. The bar shed will have 6 double sockets and 1 single socket and a light socket, which i intend to have fitted by round conduit.
Any advice greatly accepted.

It does help.

Thanks, The Sparky that fitted the cables ...etc wont answer my calls...I think maybe furloughinging or something else has affected him...I did ask what size glands were used for the hot tub cabling which is the same size cable and he said 20mm outdoor SWA Glands...does that throw light on the armoured cable size ? or not ?

No, 1.5 to 6 sq mm cables all use 20mm glands.

If its the last socket of 4 on a radial protected by 32A mcb. The cable supplying the sockets needs to be established as if only 2.5 sq mm there is an issue with the use of a 32A mcb in the first place

Thanks its a 6mm armoured connected to a mcb of 32a and is the last socket...as regard to radial or ring i am unsure as the trunking runs along all 4 walls and is hard to say unless i remove all the trunking tops....It could start and end in the cu as a ring would

You don't need to do that, a simple test will confirm.
Too many unknowns to say for sure, you really need to get an electrician to check it out properly.

Really appreciate your help and i will report back to state how things panned out

Good luck with it.

All seems a bit of a strange design, he'd have been better running the SWA back to the Garage Consumer unit and putting the bar on it's own circuit. An MCB in an Rcd protected consumer unit isn't ideal for a distrubition circuit either. If the sockets in the garage are a ring then the fused spur would need to stay, it wouldn't matter if you used 25mm cable, the entire bar area would still be a spur off the ring and the limit for that is just 1 single or double socket.

Hi, I am sure it has its own 32amp circuit connected to the garage cu..why it has a fused spur before going outside ??

Your photo shows a fused spur labelled "Pauls Bar" with the SWA cable heading out of it?

Not sure why it has an IP rated enclosure either given it's right beside a socket that doesn't. Strange setup.

After all these comments its bugging me now.. I will isolate leccy 2moz and have a look around the fused outlet

some armoured cable has its size embossed on the outside, every meter. will be something like BASEC CABLE BS123455* 3 X 4SQ MM
have a good look, it might give you a clue as to what cable it is.

It says Electric Cable BS 5467 ce 600/1000 v

pity, some cable manufacturers put the size on too.

I have taken the covers off today of the twin socket and fused spur. It seems that the twin has x2 twin and earth cables feeding it and then x2 from there feeding the fused spur with the 6mm armoured inside. This then is sent to an opened end (dead) to the bar shed.
