I need how to determine the guage of wire using amps,volts,kw & distance?

Question

Iam making an electric bus for that i need the details that which thickness of wire is suitable in which iam having all the current ratings.

Answer 1

The best thing to do is to use a table of wire gauge versus current and resistance. The tables usually provide resistance per linear foot so that for a given length of wire of a particular gauge, you can determine its resistance. This is important because the wire's resistance combined with the current that your load draws will cause a voltage drop across the wire so that you do not have the same voltage at the load as you provided from your power source. This follows Ohm's law ( V = IR). You should size the wire conservatively and follow local codes if this is for commercial or residential purposes.

Answer 2

you would favor to envision to make optimistic the #10 wire will in good structure less than the screws of switches and shops previously setting up the wire. you would no longer be able to positioned a 30 Amp breaker only because you install #10 wire because the person-friendly switches and shops are rated for 15 or 20 Amps. look at getting 1000 ft of #12, it will be less intense priced than #10.

Answer 3

Not really sure what project you are doing, maybe there is an easier way? Anyhow here is the info you requested!
wire size,current,resistance etc. Of course there will be a need for calculation. I'm sure you will figure it out.

Answer 4

depending on what country.
There is A national electric code for that.
Usually a library will have that book.

Answer 5

Buy you an "Uglies" electrical ref book $12.00

Answer 6

depends on the wire material too...

Consult www.howstuffworks.com. It really does work! I really do not know.
