I know you always get upset when people who dont know the answers respond you your IMMEDIATE DEMAND FOR ANSWERS.
I am allowed to respond to your post because you said I could only do it if I know the answers. I qualify.
If you would learn to use your NEC and how to find information contained therein, perhaps you wouldn't need to ask us to help you with your homework.
Edit-this site is for the EXCHANGE of information. It's a TWO WAY STREET! What have you CONTRIBUTED to the site?

Someone can check my work...
I am 100% sure of my answers:
1) Berlin 1924
2) The Cold War
3) Penicillin
4) Walter Winchell

Jarvis Design dot worry and am i am sorry that i put question like thata , but there is a point , because there are peolple they dont know anything and put their stupid ideas , so its not regarding to all ....SO if u know i wanna discus these questions ,,,,,
Static Design Thanks a lot ......I am in the same mind as you ,,,,but the last question i think like this IF U HAVE SUPPLYY 480V AND U NEED 120/208 400AMP I DID CALCULATION LIKE THIS
480V*AMPinput=208V*AMPoutput => KVA=400A*208=83KVA
CAN U EXPLAIN ME WHERE AM I WRONG ?
480V*AMPinput=208V*AMPoutput => KVA=400A*208=83KVA

How can a math equation have THREE equal signs?
Beside the fact that it makes absolutely no sense.
Beside the fact that it makes absolutely no sense.
8/16 = 4/8 = 2/4 = 1/2 = .5
OK, now put those numbers into the OPs' equation.
Ok i agree with you guys ....My english is not good ...and maybe i speake antoher different way but i will fix it ...the main thing that i dont think like that it is my just only speaking way ...but dont worry ,,,after i will put the word "Please" in the and of sentance and i will fix my speaking .....
408 SPARKY i See you are far from away from math this sign => it is not a equal this = sign ....Thios sign => it is math sigh which mens "Means"...i will explain you
18x=36 =>x=36/18=2
Im am saying to all who dont dont i see many of you guys dont know this sign
Now who can help me in my questions ?

Or are you trying to make "=>" into "

Alex, I'll go with a 150KVA secondary transformer and I'd like to bet it all.
Learning and understanding three-phase wiring is not the easiest thing. Once you get it you'll never forget it.
The number you need to remember for three-phase is 1.73. That number is the square root of the number 3. It used wherever a three-phase voltage is used. 208, 240, 480, etc.... are all three-phase voltages and the most common ones.
Next, and very important for any "real electrician" to know is Ohm's Law. You can google this and find out what this is on your own.
Long story short... 208 volts x 1.73 = 360. Use this number whenever you need to find a three-phase voltage for 208 volt services.
Next, 360 volts x 400 amps = 144,000 watts, or commonly known in the trade as 144 kilo-volt amps, KVA for short.
Now, since you need at least 400 amps for this service a 150KVA transformer will be needed.
They don't just give out electrical contracting licenses where I live, here they're earned.

Niceeee Magneticca !! i did the same calculation and u are absolutely right!!!!
and thanks for website ..... Guys i have more questions can i ask please ?
