So I work with all this stuff pretty often, but I'm still having trouble getting my mind wrapped around it all, so here's a few questions.
I'm still having trouble relating
volts, watts and
amps to regular
theatre/sound use. I know that most household circuits have a 15/20 amp load and that they have a certain voltage limit. 110? 220? I don't remember. But I don't quite get what all that means. Particularly amps, I keep hearing them used, but I have yet to get a good explanation.
Also, I know that on a three phase power system (ie a generator), if it's not properly grounded you get that hum on the sound system. But I don't quite understand why the ground can affect the sound like that.
And lastly, on a three phase system, what is the purpose of the neutral wire? I know that the three phases each have 120? (amps?), and I know that the neutral usually carries a fair amount of electricity, but what does it do, exactly?
Thanks in advance, everyone. I know most of this is pretty basic, but I'm just seeking to feel a little less stupid at gigs =)
