In my kitchen I have some cabinets with 10w, 12v halogen bulbs (i have no idea what those numbers mean, I'm just reading it out as its marked on the bulbs - all I generally know is higher the watts - the brighter the bulb :) ) and they are G4 socket... when pulling one of the bulbs out, one of their "prongs" kind of broke, so I shut down the mains and slowly pulled it out of the socket with some pliars.
Now I am curious, had I not shut down the mains before pulling out that broken prong, could I have gotten a shock?
I am in Europe (220v unlike the US' 110v)
If you know what you are doing, then shutting off power is not necessary. I've seen wall outlets replaced while power was still live, and This Old House on TV once had live power from the street connected to a house panel. But that is not safe practice for most people. Be safe rather than sorry (or dead). At worst you spent a little extra time shutting off power and then resetting some clocks. – sawdust – 2014-10-20T00:55:19.260
