Comment on Forbidden Tech
HereIAm@lemmy.world 3 days agoI will just regurgitate what I’ve heard. I think they are used in case power goes out and you have a generator. You need to disconnect from the power grid first, but it should then allow you to power tour house with the generator. It sounds more like a US thing.

Yes, this would technically work. Although, it would only power the hot leg the outlet is connected to which only feeds part of the house.
It’s very dangerous for a variety of reasons. Especially if you forget to shut off the mains breaker. The transformer can backfeed power down the line at line voltages, creating a shock hazard for lineman or anyone else who might have contact with the line.

Wouldn’t any repair worker ground anything they work on first, or assume it is live? I am not even a proper electrician, but “short-circuited and grounded, or treat it as live” has been the rule forever.

Not an electrician, but I would imagine the danger being if the technician checked the wire was off locally, started work and then the home generator starts feeding mid work.
