    Submain rcd fault protection

    Thanks @pc1966 For giving it so much thought. I feel that the submain does need to Be protected/meet Disconnection times. A parralel cpc is not an option. I agree that with the outbuiding fully rcbo covered that the time delay rcd on the sub really shouldnt be causing issues. I am going to leave...

    what would the Max zs be if a 100ma time delay rcd were fitted @ origin to cover the sumain? it is just poor design. Distance way to far to meet fuse disconnection times.

    Submain rcd fault protection

    If a 2 core swa was run for a submain to an outbuilding with no extraneous parts in it, but the zdb reading was well over the maximum earth fault loop impedance. Could an rcd time delay be installed at supply end to cover the submain ie increasing its new maximum zs reading? Hope thats clear ?

    Disconnection times not met

    Have you confirmed that the tns supply has not been converted to a tncs? In my view any supply to a caravan site should be TT earthing arrangement with upfront rcd time delay. How old is the installation?

    Salon backwash unit

    well for a start you are only paying for what you use. Water heating via electric is never going to be cheap, the unveted tank would continually be Keeping the water up to temperature and possibly the Water would not get used.

    Sun bed uv tubes problem

    thanks @westward10 If they were replaced with 225w replacement bulb or the ballast were all change to 160w ballast (same as new bulb) you wouldnt expect a problem. What about the difeence between electronic & a magnetic balllast being used with the uv lamps?
