    Thought this may help others considering a similar task.

    Posted on other forums by me.

    Managed to get around to rewiring the motorhome today. Fed up of extension leads from the cheap/Basic dealer install.

    If it is of any interest to anyone considering the same, here are a couple of photos....

    As we had a CBE consumer unit, this did not facilitate the installation of my type of automatic switch over. So it was removed and an MK Sentry 8 way fitted. We only needed 2 or 3 Fuses, so this made room for the contactor. Saved having an additional box.

    As the MK Sentry is made for Domestic use, there is the possibility that screws could loosen with vibration (happens in homes too but more likely in vehicles). So I used boot lace ferrules and a combination of blue thread sealant and glue to prevent screws turning.

    Just a bit of tidying up to do.

    Ah yes that's the Clive Mott version. I have one of those contactors going spare if anyone wants to give it a go for a fair price?
    I changed mine to a relay as the contactor has too much buzz for my liking.

    Circuit diagram etc here

    I have used contactors in the past for other jobs. Last one was a bit noisy on the motorhome. What relay did you use?
