Mr. Sakthivel with statements like "i want formula for
current density and formula foe area of conductor"
you sound very demanding. YOU WANT----? How about please
send me ------. Thank you.

If you can not calculate the area of a conductor maybe you
need to contact a forth grader and ask them how to
calculate the area of a circle. As for the formula for
current density you may need to go to a fifth grader. Get
off you butt and google current density for yourself and
say thank you when you respond.

Answer / wareagle

size bus bar. you can use the table at this site. note the
temperature.

Mr.Firoz Kachhi i want formula for current density
and formula foe area of conductor this in mail id
rcplelectrical@gmail.com

Answer / firoz kachhi

firstly calculate load current.
then we have std formula that is
current densty =current/area.
use std. current density for copper or aliminium
put it down in above formula and calculte busbar size.....
if u r area 100mm sq.....then we can use 50mm*2mm or 25*4mm
or 10*10....as per suitable ....very simple na??
