    go to any electrical wholesaler/retailer and ask for a 'stuffing' gland.


    see in link...pick the correct size or it wont work.

    the glands in my post are 100% waterproof at high water pressure...jet wash etc...IP68 rating.
    but the threads must be made waterproof where they enter the box.

    agreed Jim, but it still needs a stuffing gland.

    i certainly wouldnt fit a gland directly to the roof.

    If you want a truly water proof gland then look to the marine market. There is one that I have used many times and it good enough to survive an underwater experience and is used commercially and in the leisure market. It is quite a while since I last done any marine work and I have forgotten the source, I will come back a little later with the info.

    OK I have found what I was looking for, have a look at this. http://www.force4.co.uk/Search/cable-gland/

    Terry, there is another way to get your cables into the van. If you have a ladder up to the roof than its possible to run your cable/s down the ladder, it save drilling into the roof and and be added to at a later date if you want to.

    Apologies if you are already aware of this, it wasn't what you asked, but thought it worth mentioning ..

    When deciding on a cable run, try to keep it as short as possible, the longer it is the heavier the cable has to be to keep voltage drop to a minimum .. use this calculator to see what size of cable required ..

    http://www.solar-wind.co.uk/cable-sizing-DC-cables.html

    Using the wrong size cable ie too small, will reduce the panel voltage at the battery terminals and give poor charging..
