SOURCE: how to calculate cable size
This site may help. Plug in all the information about your load requirements and it will figure out wire and breaker size and even how big a conduit you'd need for the run.
SOURCE: need to find info where i can find formulas to download on the calcuaotr.
I found having formulas in the notefolio APP was easy to get to and very readable when I needed them. Cut copy and paste to home screen. If you have things in solver I just never any good at using it.

Hi,
Jane starts with 1200$ at the beginning of the first year, and at the end of the fourth year she has 1200$+300$=1500$
Use x for her annual interest rate, that means at the end of the first year she will have 1200$*[(100+x)/100]. At the end of the second year her first-year money earns at the same rate, so she will have 1200$*[(100+x)/100]*[(100+x)/100]=1200$*[(100+x)/100]^2 at the end of the second year.
At the end of the third year she will have 1200$*[(100+x)/100]^2 *[(100+x)/100]=1200$*[(100+x)/100]^3
At the end of the fourth year she will have
1200$*[(100+x)/100]^3 *[(100+x)/100]=1200$*[(100+x)/100]^4 which is equals to 1500$
1200$*[(100+x)/100]^4=1500$ divide both sides by 1200$
[(100+x)/100]^4=1,25 take the fourth root of both sides
(100+x)/100=1,05737 both sides*100
100+x = 105,737 both sides -100
x=5,737
So Jane's annaual interest rate was 5,737%.
Hope it helps you.
