Hello all I have a TT earth system supplying mains power to my Garage. The earth (6mm cable IIRC) runs from the garage CU to an earth rod situated nearby.
Whilst at TLC recently I picked up an 'earth rod terminal cover' in an attempt to tidy up the clamping arrangement to the earth rod:
However this unit turns out to be not quite what I expected and I'm a little unclear how it's supposed to be used.
The earth rod clearly goes in the bottom tube (which swivels), and then there is just a 20mm or so hole in the side of the box. Is this intended to take a cable gland for the earth cable? Or just a grommet of the appropriate size? And why the swivel? I'd have thought this would encourage small children to play with it and maybe loosen the internal clamp arrangement.
Thanks for your thoughts
