    So, my shed has a power line running out to it that is wired from a socket in our conservatory. I'm not sure how above board it is :l

    when I turn my lathe or steppers on the lights blink.

    I'm thinking that I might need some better/thicker cabling? or for it not to be daisy chain from an extension?

    any ideas?

    Really Depends on what amps your pulling but working from an extension isn't good idea in any case.!! Your just asking to burn the place down and by that I mean the house not the Shed.
    On top of this Insurance will just laugh and give you the finger when found using extension or any kind of dodgy wiring.!

    Really you want it on it's own circuit with it's own fuse and using appropriate sized wire for the amount of draw. Anything less is just not worth the risk IMO.

    I think that you will find that you will need to have an isolator in the house and a consumer unit in the shed and the cable will need protecting with an rcd I would use wire armoured cable between to two. ...Clive

    The lights will blink if they are on the same circuit, lighting is usually on a separate circuit so as not to worry you.

    Get a pro in for this one as there is much more to it than running in a bit of cable, length of run, load required, volt drop cable type, earthing and supply type. For some domestic supplies ( TNCS I think) its not recommended to extend them outside of the house so alot of the time a phase and neutral is ran from the house BD to the shed DB and them the installation is them earthed via a TT system at the shed.
    So short story get a decent spark.

    Could you post the quote for a pro to do the work if you get one. I am after the same and had a quote for it but think its a little pricey...
    Rcd, 60ft of armoured cable, 4 double sockets and flo tube - 480.

    Without knowing exactly what is getting fitted and seeing the job it might be a good price. I take it that the spark will run in the cable, drill through any walls in the way, fit distribution board in the shed, connect up cable in house and fit rcd, fit all sockets and lights in shed and wire them. Fully test installation and provide you with test cetificates. How is cable being run from house to shed? Digging trench? All in a good days work so price might be ok.

  10. I agree, there's at least 80 of parts at trade prices, then factor in labour costs at 35+ an hour and running 60ft of cable especially if trenches is a good days work, possibly 2 if he's a one man operation.
