13 out of the 101 persons on the secret list have larger battery sizes that that.

To be fair, on many occasions even when a smaller cable will suffice for electrical reasons, a much bigger size is used to ensure physical robustness of the installation. This is very true in the Petrochemical industry with external cabling. A 2.5mm cable really isn’t that strong in the scheme of things.Oldgreybeard wrote: ↑Wed Nov 23, 2022 9:23 pm That bloke from Artisan REALLY hacks me off, the bloke's a chancer, who's been trying hard to gain views on YouTube as a business for the past year or so, and is using more stupid clickbait facial expressions and video titles every week.
He also has some complete blithering idiots working for him, who are so clueless I'm surprised they ever got through their apprenticeships. When asked what size cable to use for a TT earth electrode one of his blithering idiots said it had to be 16 sq mm, despite the fact that at the very most that cable only needs to carry about 100mA (the true answer is that 2.5 sq mm is fine, just needs to be mechanically protected).
One of them damned near caused a major structural failure in a timber frame house, by chopping out about 30% of a structural support pillar, having already cut away (and not replaced) the essential vapour tight membrane (so that pillar will most probably rot out in a few years anyway). I got sent links to a couple of their videos by a friend, who sent me them as a laugh and an example of just how dangerous some trades people are.

The regs mandate that the cable be mechanically protected for most electrode locations though, IIRC, so if the cable has to be in conduit anyway then I would guess that it doesn't really need any additional mechanical robustness by being oversized for the job. Certainly both of our earth electrode cables are in conduit. The one for the house is in a buried plastic conduit, the one for the garage is a short length of galvanised flexicon (the garage is around 30m away from the house).Lincs Robert wrote: ↑Thu Nov 24, 2022 4:56 pmTo be fair, on many occasions even when a smaller cable will suffice for electrical reasons, a much bigger size is used to ensure physical robustness of the installation.

A couple of years ago I contacted him regarding an EV charger install I needed - he didn’t even reply to my email
