At least you have a 1 in 3 chance to find the live hole. One is a neutral with no voltage and one is a ground also with no voltage. Even if you do hit the hot one you still have to make a path to ground. Still though, turn the juice off before opening it up. Electricity is very unforgiving. As an electrician for the railroad I work around 750 volts or more and am extremely careful around anything live no matter the voltage.

@geluregis if you are working with live electricity and not wearing any protection AND touching metal, it's not an accident it's natural selection.
You should always turn the power off when working on electric. It's pretty foolish to work live and it takes a thorough understanding of electricity to do so.
The voltage in most house circuits is to low to do real damage. I speak from experience

Aaaaaand wrong, 120/110 has killed many many people, it's whether a load is transferred across the chest (also other considerations such as size of load, whether it's phase to phase short...... yea)
If I had my way ALL new screws would be required to be Torx unless there were some strange design requirement.
Slotted screws don't retain the driver well, Phillips screws cam out and strip the head, square and hexagonal slot screws can't handle as much torque or get stuck on the bit. Only Torx avoids all of these problems.
