Installing a 5/8" earth rod

[andrew8902]

Hi. I have installed a 5/8" earth rod but am having issues with the plastic box cover that sits on top. I purchased one from TLC but it seems too small to fit properly (see photo)
Also is there a specific gland to use where the 6mm2 earthing conductor exits the box? I don't want anything climbing in there

Thanks

Those boxes are a bit pony. They are what they are. I try to always fit an earth pit for rods.

The Whiska 20mm glands will probably go down to 6mm cable diameter. If you really want it properly sealed (which is kind of pointless here, but for mechanical rigidity) then you might find that some PVC or self-amalgamating tap on the cable where the gland ought to grip it will do to give the gland enough diameter to close on fully.

This Is a bit bigger, available at most places.

Not matter what glands you use the box will fill full of water/woodlice/spiders/mice/other horrible things within a few months anyway...

The one Midwest has linked to is a much better option.

6mm cable to an earth electrode should really be run in conduit. The entry pipe to the earth box is made for such a thing.

And the conduit can be neaty solvent welded in place, thus solving the initial problem.

If your really struggling to get a fixed conduit, atleast put a 3 inch bit in, adaptor and then stuffing gland or flexi conduit onto the adaptor.
