PC components runs on +12v, -12v, +5v, -5v, +3.3v and have earths as well

I can talk about electric...... At work We run
33,000V
11,000V
(at my old place we used 3.3kv - 3300V)
690v - I know an odd voltage but its a European standard
415v 3 phase - like any industrial site,
240v
110v
and -50Vdc for control (so we have a battery back up)
and of course we have the 4-20ma Loops at 24v

Also we have grid on site - but we aren't allowed to touch that!!!
