Wiring of shed

[cpljones]

Hello I'm want to put electric in to my shed ,at the moment I've run cable from my consumer unit into my shed whats the next step.I have spare fuse space in my consuner unit for the supply, the shed is used for general diy and to run a freezer approx 2 sockets and 2 lights

What supply does your house have? TNS/TT/TNCS?
What cable have you run?
Have you read Part P?
You will need to install another CCU in your shed and run everything from that.
How far from the house is the shed?

Hi I dont know what supply I have ,Ive run 2.5t&e the shed is approx10/15 m from consumer unit I dont kow what part p is?

 

[Maxxy]

I'd advise getting an electrician in. What you've done so far is already wrong.

Thanks I''ll take your advice

Just so you know what to expect: He will probably have to lift a few floorboards to run the cable from your fuse box out of your house. The cable will probbaly be 4mm or 6mm three core armoured. He will either clip it to the wall or bury it depending on how close the shed is.

(If the shed is back to back with the house he may run straight into it from the house)

The sparky will then fit another consumer unit in your shed, and wire this cable in as the feed. He will then either use mini trunking in the shed, or run armoured cables to metal sockets, and armoured/trunking to junction boxes for the lights to be wired into.

Depending on your house supply (and distance of shed) he may either install an earth stake, or use the house Earth.

The shed sockets should be fed off an RCD, especially if you are going to plug a lawnmower etc into them.

All in all, id expect it to take 2 maybe 3 days.

Get a few quotes from local companies before deciding who to go with, so you know you are not getting ripped off.

Preferably use an NICEIC approved contractor, and make sure you are giving test sheets after confirming it has all been installed and tested to current regulations.

Maxxy,

Why are you recommending only one of the five possible approved bodies?

 

[Maxxy]

No reason in particular, other than the fact its the one that everyone has heard about and knows. Feel free to add the others

 

[THRIPSTER]

You are kind.


It`s just to stop Building Control thinking that there is only one body whose people are capable. Which tends to make the NICEIC think they are more important than they really are.

BSI
ECA
ELECSA
NAPIT
NICEIC

Don't Corgi offer it too now, or is still in the pipeline (no pun intended..ok maybe a small one)

I think the Corgi one is something to do with Napit.

Oh, one final point, freezers don't work well in sheds, especially in winter

apparently what you really need to watch in cold conditions are fridge-freezers as they often only have one thermost.

i'd imagine seperate freezers would be less of a problem.
