voltage drop

[curranelectrica/v]

what is the voltage drop for 100 amps going 550 from utility pole . I have over head triplex for the first 200 feet then I can run in conduant using copper may be 250 MCM
& for the triplex 4∅ thank you

Assuming

• 240 volts
  
• 200' 4/0 AL
  
• 350' 250 kcmil copper

I come up with 6.9 volts dropped or about 3%.

OP didn't spec voltage.

OP didn't spec voltage.

I know, that was why I said I assumed 240. but the amount of volts dropped would be the same, just not the percent.

That wasn't really directed at you Bob, I see all 3 assumptions. I was thinking OP may provide more info.

Also would like to add that OP didn't say if 100A was the OCPD or the actual load.
