    Mornin' all,
    About a year ago I done some work at a neighbours house, part of which was to install a new earth electrode, in fact I had to fit 2 rod's to get a good reading, ended up with 62 ohms which I was well pleased with. I done some minor work over there yesterday and just out of interest I checked the Ra, it's now almost double what it was a year ago! I'd have expected it to be lower if anything, considering all the rain we've had recently. I had a look at the connections but all looks just as I left it. Not too bothered, especially as all the Zs's are around 0.40 ohms, (pme nearby) but just a little puzzled?

    put it done to nature sen
    I already have lamps, just a bit curious though.

    Still below 200ohm, so considered stable.

    i've never heard of putting 2 earth rods in, you just make them longer don't you?
    never 2, parallel paths springs 2 mind

    It's quite an acceptable method fast, put as many in as you like, parallel paths are all good in this instance!
