we have 240volts at 10amps here, so 2400watts, but 15amp power outlets are also a common thing, so 3600watts //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
you could also probably draw twice that much for a few seconds anyway... long enough to get a TL reading, and not do any perminant damage to the wiring //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

You ****. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

We can get 240v 80a no problem. If you pay a nice price they will deliver 480v 3 phase with as much current as you could need (with in reason) to run industrial sized A/C's, pro audio equiptment, among other things.

My school has a 480v 3phase drop and there is a giant closset with a transformer in it by every air conditioner unit that drops the voltage down to 120v single phase after the 480v runs the AC. Most large buildings here do the same.

Most resedential lines are 1920v 3phase (IIRC) with transformers that break it down to 480 3 phase for individual streets and then every third light pole or so there is a transformer that breaks it down to 240v single phase and that is what goes into the houses.

our 3 phase is 415 volts...

how can yours be 480 volts? :s

ah, the higher frequency maybe... hmm...

60Hz is the singlephase standard. I dont know what the 3 phase is. It could be 415v. It's 4 something and 480 rings a bell.

no, see, its still 60Hz, while ours is 50Hz...

if you have a higher frequency 3 phase, the sinewaves will add differently, maybe resulting in a higher voltage... or maybe you're just wrong lol

From a quick google.

It says it steps down 480v 3phase

440v is normal 3 phase here.

unless that link above that i didn't read otherwise, that's what i've always known

i wanna break into a transformer and safely hot wire my sub and a good sized breaker to it :0 thatd get a nice burp //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif who has a TL they wanna lend me?

you wont get much sound from a 3 phase signal...just run it 240v //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

lol, trust me 220V with enough current is WAY more than enough. 24,000 watts at 2 ohms. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

(Of course just remember to get at least 110A)

440V? Eeek...thats what 96,800 watts at 2 ohm! There would be nothing left of the speaker.

Once agian, you wont get much sound...or movement....from a 3 Phase signal.

3 phase power is putting a signal on top of a signal on top of a signal so that there is always one rising in voltage, one dropping, and one at 0. A speaker will see it as almost DC current.

EDIT:

Wikipedia does a decent job of explaining it. To give it true 3 phase power you would need DVC or QVC each voice coil would be phase to phase in opposite polarity so it would only move one direction and move very slightly as the coil burned...

i can tell you this much, i wired my old w6 at 3ohms and plugged it into the wall in a sealed box and it was louder than it ever was in my truck... for the 10 seconds it lasted anyways...
