Correct way to install an earth rod.

[Millboy]

Hello people. This week I've got to install a rod at a property where the gas is being used as the main earth. I've installed them before for temporary generators etc but never done a permanent one. I'd be grateful if someone with more experience could help.

The house is surrounded by concrete, so I'm thinking drill through that close to the house, bash the rod down, and screw an adaptable box to the floor with the connection inside all labelled up. Then 16mm clipped a short way and through into where the board is.

Thanks guys.

Ps its an overhead supply.

It’s taken a while E54 but the bible thumping has worked.

What can i say!! All that needs to have been said, ...has been said!! lol!! And not a single mention to date, of that junk 200 ohm Ra, ...I'm impressed, i really am!! ...lol!!

The only thing i can add, is try driving in those rods with a rotary stop SDS, it really is much quicker and your not left with a big hole at the entry point from the flexing of the rod each time you hit the thing with a club or sledge hammer!! Don't forget to buy the driving head/pin that threads into the rod connectors....

Agreed and more importantly the rod doesnt move and you end up clubbing yourself,also in relation to the bible bashers tell them your a satanist I did and I,ve never seen anything go down my drive as fast that wasn,t followed by my large GSD lol.

My fear is always with hitting a drain or storm drain pipe as the services are normally easy to find but drains seem to run anywhere and not always with indications on direction of run on older properties. a couple i've done I cringed with every smack the the hammer.

At least if you go through a drain, the readings should stay nice and low

Well it went ok apart from the snow! Tw*tted 3 down and ended up with 24.3ohms which I'm fairly happy with. I like the tip about getting them down with an sds drill but that would only work with the smaller rods as far as I can see. Yes I was a bit scared of hitting something as there could be anything that deep, unexploded bomb crossed my mind lol!

That's the worry with earth rods for me.

In the the UK you never know what is under the ground or how far to risk digging, putting in an earth rod is a night mare really, the damage you could do if you hit something could cost you a fortune, how can you tell what's down there?

I'm not a scaremonger but if I drove a rod down around here I would always be worried what I would hit.

I guess that's why the skinny little rods are so popular.

Why do you think that?? That's exactly how the professionals drive rods in the ground where the soil type is known to be good!! OK, they will be using heavier duty equipment than most electricians will carry, but then they will be probably going down a lot further than you intend too, ...like 6 to 9m!! What you need is an old socket that fit's over the driving tip and rod connector that's welded/brazed onto an old SDS drill shaft or similar. I still have mine, that i had made for me over 15 years ago... My one is for 3/4'' rods, but probably also good for 5/8'' rods too, if a bit of a sloppy fit...lol!!
Or of course, you can buy a propriety off the shelve job, but some can be on the expensive side... lol!!

Those thin rods are are next to useless far too thin and far too short, and can't be extended!!! They should be removed from the market place altogether full stop!! lol!!
