Connecting to a prefab shed

    I am looking to get a steel shed later this year, something like a Shanette, Steeltech etc. They come insulated and wired for electricity.

    When we had the house rewired a couple of years ago I got the electricians to leave a cable out the back of the house for a future shed.

    I'm just wondering what the actual connection process typically is?

    Is it a matter of digging a trench, running the cable and just connecting into a fuse board? Will a sparks dig the trench or just do the actual connection?

    Is this the kind of thing that's such a small job I'll find it hard to get someone to come out and do it?

    Pretty much as you described. The sparks will have to test and certify too.

    Generally, yes.
    Will a sparks dig the trench or just do the actual connection?

    Doubtful as it must be at least 3 feet deep.

    Hard to say.

    Your post made me look it up. I was wrong, there are various minimum depths depending on a number of factors such as cable type. It’s explained in table 52B.

    Thanks for all that. Where is table 52b published? Would be handy to get a look if I'm going to have to get digging!

    In the National Rules for Electrical Installation, ET101:2008
    This costs around €90

    Anyway the answer is: In a domestic installation an SWA or NYCY cable direct buried in the ground must be buried to a minimum dept of 450mm.

    The regulations also state:
    Suitable indication shall be provided above a buried cable at a distance of approximately 300 mm vertically below the completed surface, or at half the buried depth, whichever is the lesser.

    Can you not clip SWA to the wall?

    Got to be cheaper than trenching :eek:

    As above, yes you can.
    But that isn’t much help if the shed isn’t close to the wall.

    Real world experience talking there I bet!

    Could you use a catenary wire? Is there a height that it has to be at?

    Yes, as it happens I have seen a few sheds that were not close to walls :):D

    Sure, it mightn’t look that great but it might be quicker and cheaper.
    Depending on the distance poles may be required.
