Stiff voltage source = low impedance voltage source= good voltage regulation.

I guess you could say that the NEC limit of 5% or 3% is actually specifying "stiffness."

If homeowners and household stuff, especially motors, could tolerate the voltage dropping 30% when current is drawn this 5% limit would be considerably more.

That's the problem with 12v high current systems; every little millivolt counts, every connection must be excellent.

Get a solar panel and beam a spot light on it from the house. :D

a voltage source whoa internal resistance is at least 100 times smaller than the load resistance.
so yoyo, are the conductors carrying the power to the shed part of the load or part of the source?

well, since NEMA mandates a +-10% tolerance, I would say this is a moot point

and that is germane to the question at hand why?

It was just as confusing in English.

Ya know you remind me of Prot in the movie K-PAX. So my question is .. How long do you plan on visiting?

Could possibly save some $ stepping up the voltage for the 400' run, then stepping it back down again. Granted transformers aren't usually very cheap but this will allow substantially smaller wires and conduits, thus if the amt of savings on wire & conduit exceeds cost of transformers...

He's looking to run a light and possibly a drill motor in the cheapest way possible and you want him to install transformers??????

could someone please link me to what i need, and what i need to do exactly
I think the OP is long gone since we were not able to ' link ' him to exactly what he wants in "cheap" power to the shed. The above statement was his last contact with the ongoing thread.

It might be cheaper to purchase a small generator than run wire for a 20 amp circuit 400 feet.
