Hello everyone, I'm a complete newbie when it comes to electrical, but I've been reading as much as I can and trying to build my knowledge. So please bear with me.
I'm working on running power out to my shed. It is a 60 amp subpanel, that's approximately 210 feet from the main panel. Now I know at this distance I need to be worried about voltage drop and that I should try to stay at less than 3%. The shed will be used as a small workshop, with small power tools(no 220 runs). Shed size, 16x24.
My questions:
1. Since the subpanel is 240, and all of my runs off the panel are 120, should I only be worried about the voltage drop on the downstream side of the panel(to outlets, lights, etc)? Or should I be worried about both?
2. Does code require that you remain at less than 3%, or is that a recommendation?
3. I had planned to run 4-4-4-4 aluminum urd, and 4-4-4-6 SER(inside), but it looks like this might not be acceptable according to some online calculators? But even with the online calculators, on various sites I get different results. If I stayed at less than 5%drop, would that be ok? Or do I need to go up to 2-2-2-4?
Thanks for your time!
