Electricity in Poland: plug and voltage? [73]
Also, what is that internal switch called which keeps a light on for 30 seconds?
You get those in the UK too sometimes especially in the hallways of flat conversions, though they're much rarer and I haven't seen a new one for a very long time. It's just a simple mechanical thing. Movement sensors seem to have replaced them.
nd I'm not sure why, perhaps because of the loose sockets and bad stuff I see all around.
The loose sockets are very common - probably due to the way they're fitted (though I once heard a Polish lady married to a Brit swear blind she'd never seen a wobbly socket in PL !). Generally the electrics in PL are OK - just a different system to the UK (the UK system of ring mains is unusual, partly due to lack of copper during post-war reconstruction). Perhaps I've been lucky. I used to get a tingle from the sink when the electric kettle was on (this in a fairly posh 1991 building), I've had wiring earthed to old lead pipes that had been replaced by plastic ones (I also had that in the UK, so not just a Poland-specific problem) and once, believe it or not, (again in the 1991 building) had several sockets which were blanks - they were fixed to the wall for decoration, but nothing, not even a hole, behind them!
