This will give Archaeologists in the future many hours of head scratching trying to work out what it is

A down to earth video 👇👇🌎🤣🤣🤣

Nice clear video. Would be nice to see a comparison of £15 earth rod vs £200+ disk.

I think John Ward did such a test and the disc was far better than the rod. Also there may not be a good place to install a rod.

If you could also use £200 worth of rods that would be a novelty

There is a recommended depth of 600mm, this is so its below where the ground could become frozen. The resistivity of frozen earth is much higher than the ground in a temperature abovd 0c. Thiscis from BS7430

Great video as usual Guys👍

Thanks Gary 👍🏻

Amazing video and very informative. If the supply at the origin is TN-S, however, do you need to isolate earth and use earth electrode like you’ve done here or can you use main earth/CPC from origin?

JW got his down to under 20ohm using the conducrete with the disc. Did you consider it at all?

Nice video 🎉

May I ask if you recomend using combined tt and tncs .

Whats the benefit of this over a copper grid matt at half the cost

Very strange you didn't do a high current test

We have used over 10 of these now and absolutely no brainer. Earth rods are obsolete in my opinion. We look after two camp sites in south Devon that have awful sandy soil which earth rods do not work at all. These discs have stayed constant results for last 3 years. Must point out you should really use the conductive concrete they produce to keep the results consistent and no fluctuations between seasons

Works better if used with the kitty litter stuff. I can't remember the name off it.

Hi are those Condu Earth discs fully recognised and allowed under BS 7671 Being there American?

@@travoltasbiplane1551I’m pretty sure it’s fine if John Ward/JW is using them… Also one of Sparky Ninja’s videos discusses the merits of the Condudisc, so with those authoritative sources, I was very comfortable using one myself. Vastly superior to an earth rod - in terms of corrosion/longevity, as well as providing a much better earth. First time I have seen one used without the Conducrete though. I got a reading of 14.9 ohms with mine.

@@robinpenny3193 well yeah Sparkyninja and John Ward are mates so that makes sense. No one said anything about them not being any good. The discussion was about whether or not they had a British Standard - the absence of which would mean a departure from BS7671. Which in of itself isn't a problem if you as the designer are satisfied that you have achieved equivalent or better levels of safety. Just because your favourite KZread 'authority' does a video on them doesn't automatically infer compliance when you sign that certificate... It's still down to you. That was all that was being said. But yes I agree they look good. But that wasn't the point. ;)
