Voltage drop in service entrance wire
Voltage drop in service entrance wire
(OP)
I was recently talking with a design tech and we were comparing Vdrop data and his calculations were quite different from mine. I asked him how his were calculated and he said he was just using a PC based calc that someone gave him. Not saying his are wrong but I would really like to figure out where the discrepancy is.
Someone here willing to post a formula along with referenced data for the calculations?

But R is not just R, it is actually Z for voltage drop. The X:R ratio of Z may be significant and the phase angle of the I may be significant.
How about you post your formula?
