I've got a wooden house. A new roof has gone on. After the removing of solar hotwater pipes, there is no longer any path to ground from the corrugated steel roof.
(How do I know? One of the screws cut into a cable and electrified the whole thing. No RCD tripped. Golly.)

Would you strap it to earth? To a sacrificial anode? Neither? What reasoning please? We live on top of a hill and have lovely thunderstorms.

Is it usual that domestic mains electricity in Spain isn't grounded?

We're getting it grounded at home, which I thought might be an anomaly, but now I'm in the library and getting the same tell-tale tingling sensation when running my fingers along the surfaces of my laptop.

If #GreenParty #UK wants to succeed, they need to reformulate #transport policy to offer more #carrots instead of sticks..

* Keep same timescale for bans of *new* #petrol and #diesel cars as rest of EU

* Encourage and facilitate development in #EV #charging infrastructure to point its as easy to find and transparently priced as #petrol and #diesel

* Invest in training and education of #mechanics (both for conventional and EV cars) and #electricians where private sector is lacking

And only *after* they have got power start advocating such things as full bans of #petrol / #diesel cars and #scrappage schemes - reality is many suburban motorists are going #electric anyway without having to push too hard, and 20 year old cars are often unrepairable due to lack of spare parts..

I built a thing fedi people 🤗🎉

#Electricians please look away, no wiring crimes habe been comitted here.

"AI companies like Meta and OpenAI have been offering multimillion-dollar pay packages to top talent, hoping to lure the best researchers and engineers away from their competitors. But there’s another dimension of the AI talent wars that has garnered far less attention: the massive shortage of electricians, plumbers, and heating and cooling technicians in the US who can build the physical data centers that power AI.

The Bureau of Labor Statistics estimates that between 2024 and 2034, there will be a shortage of roughly 81,000 electricians on average each year in the US, measured in terms of unfilled jobs.

The BLS projects the number of employed electricians to grow 9 percent over the next decade, “much faster than the average for all occupations.” One McKinsey study came to a more dire conclusion: Between 2023 and 2030, it estimates that an additional 130,000 trained electricians—as well as 240,000 construction laborers and 150,000 construction supervisors—would be needed in the US.

The rapid construction of AI data centers across the country is likely a major driver of demand for skilled tradespeople.

According to a May blog by the International Brotherhood of Electrical Workers—a labor union representing electrical workers in the US, Canada, and US territories—some local affiliates “are facing single data center projects that require two, three, sometimes four times their current membership.”"
