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?

Are you sure you're not missing part of the question??

Can't remember right off, maybe 65??

3)In Raceway u have 5 conductors what percentage you must use for ampacity of wires ?

a.50 b.60 c.70 d.80

Table 310.15(b)2a states you must use 80%

4)U have supply 480V.Your building need 120/208v 400a service.what size transformer u must use ?

a.150KVA b.200KVA c.500Kva .d.600kva

480V x 400a= 192000VA = 192kva so use 200kva

or

Can you please help me answer these questions.

Batik, you need to acclimate to our culture a little.

I would answer, but, I think I am only 99% sure.....

and its

ANSWER THESE QUESTIONS:whistling

His OP looks like a Nigerian scam email. :laughing:

..........Batik, you need to acclimate to our culture a little.

Beside the fact that it makes absolutely no sense.

.............480V*AMPinput=208V*AMPoutput => KVA=400A*208=83KVA

CAN U EXPLAIN ME WHERE AM I WRONG ?

how can a math equation have three equal signs?

Beside the fact that it makes absolutely no sense.

OK, now put those numbers into the OPs' equation.

8/16 = 4/8 = 2/4 = 1/2 = .5

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 ?

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.
