i am in the czech republic working and we've had some equipment issues at the facility that have led me to test the receptacles around our office spaces and i'm finding something that puzzles slash concerns me.
the voltage between the two hots is ~233, fine and well. BUT, the voltage between the left hot (for lack of a more specific description since it's the left pin in the receptacles) and the neutral pin is ALSO 230 or so, as is the voltage between that leg and the screw on the receptacle plate. the potential between the other, right hand pin, leg and the neutral is effectively 0, as is the potential between that leg and the chassis screw.
my question is, is this correct? i assumed not. i would have thought both legs would have the same potential to the neutral or ground, but it seems every receptacle in our whole wing is this way, so i am wondering. we had the facility electrician out and he promptly tripped the breaker twice when inserting his meter into the receptacle, which didn't give me much faith in his abilities. he says this voltage scenario is normal.
any others have experience with this they can share, much appreciated.
thx.
mods - if this is too far off-topic, feel free to move, just wanted to put in somewhere it had a chance of getting a response, thx.
