SCHOOL ME ON RV OUTLET VOLTAGE DROP CALCULATIONS

[Dsg319]

At this point I have to presume its a balanced panel.
According to your Calculations, If I do it for 50:
2x21.2x50x285= 604,200/7.2=83,916.
Next size up 105,600 which is a 1/0... should cover it also for 50amp 2H,1N,1EGC

I'm gonna check to see if they have a 2/0 direct burial 2H 1N 1EGC

Yep I just done the math for 208volt load of 50amps, and it came out 1/0 as well.

You do understand that voltage drop is dependent on load current and not breaker size, right?

Sure, you can use 50 amps if you wish, for the worst-case scenario.

Yeah that’s what I was doing worst case scenario sense not knowing a load calculation of the unit.

YOUR BOTH RIGHT!

1. Your Right! (2 x 21.2 x 285 x 50=604,200/6.24vd= 96,826cm ( 1/0 as well ) ***I forgot to do 3% of 208. I did 7.2 on mine LOL!

2. And your Right! (Sure, you can use 50 amps if you wish, for the worst-case scenario.) ***That's 285 feet, I'd rather use the max if possible.

I appreciate you guys helping out with this...
