ECN Forum Forums Technical Discussion Electrical Theory and Applications Voltage drop calculation

Another handy reference for your computer, for those who do not have it, is:
edreference.com
(I hope this works).
It has voltage drop, short circuit calculations and some other stuff included.

I like this one.

2xLxIxohms per k from table 8, divide by 1000
L= length
I= amps
2= distance both ways
For 3 phase .866xvd
