    I have a detached garage and want to run electrics to it.
    I plan to go from the consumer unit in the house (which has a spare way on the non RCD side) to a new garage one with 40A RCD main switch a 16A Mcb and 6A Mcb.I have some 4mm 3core SWA cable left over from another job to run the 25M from CU to CU.
    first question is the 4mm SWA cable big enough?
    2nd Question what size MCB should it run from in the house?

    So you're an electrician then??

    If you're an electrician then why the heck don't you know the answers to these BASIC questions???

    Well Clarky,

    I have to agree with the other comment here, if your a sparks(?) who has some SWA left over from another job to do your 'lectrics (cue Handyman terminology) you must be able to calc out your cable size prior to work commencing.

    Also, see part P is doing its job as usual..

    No I am not an Electrician hence asking the questions. I am actually a chippy. I intend to do most of the work myself and have it connected up tested and cretified as I do with all my electrical work.

    My original reply was,

    Why not ask the sparks who is (ahem) going to certify YOUR work that your doing, rather than coming into a chatroom and asking us how to do it?

    I give up!

    I didnt think that because someone has some SWA left over from another job that makes them an electrician. By the way I have done Part p just havent registered with a governing body to self cert my own work. Becides I normally have a sparks do most of my work, except my usual guy has just moved to australia.

    I have done Part p

    Sorry Pal

    If you have done part P Basic cable calcs should have been covered on the course work and if you would like to know how I know that, its because I teach THIS subject part-time!
