Voltage drop

Probably because you're all over the place. They've answered each of your questions the six different ways you've asked it.


Then make your own conclusion. Worried about it? Do some math or don't do some math; use a rule of thumb; see what is inside the back of the van to use; do as you please unless you are installing a circuit for a fire pump or sensitive electronic equipment, as Don mentioned. There's no right answer, it's entirely up to you as the designer of the circuit. There's been occasions I've used 1A as my load for the math, and other times I've used 20A, it depends on your opinion of the conditions and what they want to pay for.

(Edit to add: getting back into the swing of things and made the rookie mistake of not noticing there was a page two, whoops!)
You did good! :)
 
Finally a good response
It's the same as the rest of us have been saying. In nearly all cases the NEC does not dictate a maximum Vd but there are other considerations. Local code is one of them. Lack of tolerance of lower voltage at the other end of a conductor run at a calculated load is another. If you are looking for a simple one-size-fits-all limit to Vd you are not going to find one.
