NEW SHED ELECTRICS

[eddiesolo]

My work shed has been using just a extension lead, this has served very well but it is time to upgrade. 


I have gotten a 100amp 2 mcb's consumer unit, IP 55 rated. 32 amp for socket and 6 amp for lights. I will only be using the socket though at the moment.


25 meters of Hi-tuff 2.5mm 3 core outside cable.


Stainless steel and rubber, marine grade P-clips. 


2 gang double socket and back box.


This will be a joint effort with all the family pitching in as my back is still not very good, but once done it will be safer and tidier.

If you are going to suspend the cable, dont forget a stainless steel wire to hang it from and UV resistant strips to hang it with.
I would recommend putting them in the ground. Not that much more bother, just need a shallow trench and some flexible cable pipe. (not the stuff you use indoors, propper outdoor cable tube). then cover that with a hard plastic "no dig" strip. Just done ours over from aerial til underground. took about tree hours in all but that was for both the stable and the barn! Sounds a lot of work but makes life a lot easier painting the house and such. No cables to hang the lader and the such,


Also is 32amp not a bit over the top? What are you running in there an arc welder?!!? more importantly, what are you connecting to in the house....If the CB in the shed is over the cb in the house you will be forever running (lol) in to the house to reset the CB in there. I would have thought that 16 amp was more than enough.


Anyway I will now let someone that is current in their certificates come and tell you how to do it correctly.


hope all is well otherwise.

If you can bury it, do so Particularly if there are trees nearby, saves your power cable from falling branches  etc.


If I remember correctly, when I had power run to the workshop and garage at my old house to meet regulations if buried it had to be armoured cable.  But as Ian said someone with a current certificate can advise on the Regs.


I only ever sold the stuff never installed it.

The unit comes with a 32Amp as standard, it will be running just lights, AB, booth and the radio. If cold a Halogen heater and if warm a tower fan. Although I do have a 16amp spare CB. 


The cable is armoured and will be run from the house, under the decking and run along the gravel boards to the shed, there is no grass to cut and is all paved, nobody goes there. From there it will be taken up a post that is next to the shed and then into the shed, one foot at most from post to shed, either do a slight loop for water to drip off or may house in tubing from up the post and into shed, either way I will using rubber gland for cable into shed and then sealing with sealant. 


I know that with the UK regs it has to be certified if you're adding or modifying the current electrics and I have someone that will help me for that. I also used to do electrics, granted a few years ago, but still know enough to keep safe and make sure that things are properly done...hopefully


Thanks for the input Ian, always worth while getting other opinions as you never know what you may miss or an idea that seems better.

Seems like you have everything sorted Si. 


But me personally three things I never mess with are:


1 ~ GAS





2~ ELECTRIC 


And 3 WATER I  I leave to the professionals
