DC voltage drop

[mta145]

Hoping that someone could help verify what i am getting...
Voltage is 420 DC
Load is 217 amps
Conductor is 300 mcm AL
I am coming up with 1% voltage drop is this correct?

420v DC
217 amps
Cunductor is 3 sets of 2/0 AL
VD = .7%

Any help on this would be greatly appreciated

You would need to know the conductor length to calculate voltage drop.

You would need to know the conductor length to calculate voltage drop.

And the temperature.

300:At 85?F I get 0.00621%/ft

(3)2/0:At 85?F I get 0.01396%/ft

300:At 85?F I get 0.00621%/ft

(3)2/0:At 85?F I get 0.01396%/ft

Calced again and got:

300:At 85?F I get 0.006252%/ft

(3)2/0:At 85?F I get 0.002084%/ft

update with length oops...

update with length oops...

Length is 130' Ooops. Sorry...

Then I get:

300: At 85?F I get 0.807%

(3)2/0: At 85?F I get 0.605%
