I was wondering if I could get some help with a math problem that is facing me.
My school is having a massive outdoor concert, and since my job is dependent on electricity, I want to get some out there. I am getting a 60Amp breaker box, but I need more then 60 amps.
So I am going to be running power cables out from outlets of my two theater spaces that I am near. Distance from the outlets to the stage is about 250 feet. I just bought three 250 foot cables, 14-3 AWG and some edison plugs to wire on them. I know 12 gauge cable would be better, but the budget wasn't there, and I ran the idea by an industry professional who said it should be fine.
However, just for my mental rest, in practice, am I running into any problems with running 15 to 20 amps through this cable?
Also, what kind of voltage drop would I be getting? I'm in the US, so its around 120 volts at the outlet.
