@SuperSluether@tech.lgbt @tryst@meow.social @melroy@mastodon.melroy.org @KayOhtie@blimps.xyz The audio is some old recording from England, if I remember correctly.
It's kind of a meme now especially under professional electricians.

(Training some myself, this kind of video is always nice to make people think about electrical safety)

@Erpel @SuperSluether @melroy @KayOhtie @tryst I once had a customer who said "I get a shock when I touch the sink and the washing machine"

Told them not to touch the sink and the washing machine!

I then proceeded to touch the sink and the washing machine. Oooh tingly!

I'll just touch it again to make sure. Yep. That's an electrical fault!!!

@SuperSluether@tech.lgbt @melroy@mastodon.melroy.org @KayOhtie@blimps.xyz @tryst@meow.social @Jencen@furry.engineer Depending on the voltages a RCD (GFCI in north America) should catch that.

we feel way smaller currents than the ones that make those trip rhough

@Erpel @SuperSluether @melroy @KayOhtie @tryst I'd say it was about 5-10 mA
But a lot of houses UK side still don't have RCD stuff. I imagine it's more now than when I was a site spark 15 years ago.
But that was the main part of the business at the time. Board changes to meet RCD regs

@Jencen @Erpel @SuperSluether @melroy @KayOhtie Had this exact fault at my parents' in Italy. The supply was TT, but the spark had wired it as TNC-S, so there was a few volts between the CPC and the water pipe. A ground rod and separating N and E fixed the problem.
