Looking at a R.V. park voltage drops on distances so great. Ideas???. 35 sites two 50 ampers then rest 30-20 amp aprox 100ft to ist then 80 ft between each & two rows.
Makes for some long runs
9600x2=19200 plus 3600 x 33=138000
138000 x 42%(table 551.73)=57960 divided by 240=241.5 amps.
for service calculations .
each row I take it also by 551.73

Pnl ---------------------------------------
----------------------------------------
around 1400 ft each row
additional rows i know would help.
lugs at most good fer 250mcm '
more rows possibly needed
anyone run into this before?

Can you move the main distribution to the center of the rows? That way you would have 4 shorter runs instead of 2 long runs.

That is what they try to do in the parks here. They set transformers and maypole out to the lot runs. We found out the allowable calc is probably not going to be enough with these new land yachts.
They tend to use most of the 50a you give then when the AC is on
