How far can a 1hp pump be from source?
I need to run a 1hp well pump that is 500ft from my breaker box and am trying to do it cost effectively.If I use a 5kva gen its going to cost around $500(plus fuel), 10/2 wg UF wire will cost about $400 plus burring cost,wind mill $2500(forget that or solar about same.So I guess I am asking "Will 10ga be large enough so my voltage (probably will need 10-20 ampish) drop be too great.Any suggestion?

I run a 3/4 hp well pump on 10-2 wire. It is about 800ft from the panel. I have no problems in 10 years. This is run on 120v not 240v, I don't know if that makes any difference. Also, I have the neutral grounded to the well pipe, I don't know if that makes a difference either.

Given a load current of 1 AMP, and using 18 AWG wire, how much voltage drop can we expect at the load end for a 350 foot run of paired wire?
Using the chart, we match the row for 18 AWG and the column for 1 AMP and determine that voltage drop per 100 feet is 1.27 Volts. By dividing the paired wire length by 100, we get the factor by which we need to multiply voltage drop per 100 feet to determine total voltage drop. Therefore, 350 feet divided by 100 equals 3.5. Multiply 3.5 by 1.27 volts drop per 100 feet to get your total voltage drop. Thus the total voltage drop is 3.5 times 1.27, or 4.445 voltage drop for 350 feet.

PaulofHouston--un-related question, I know, but hopefully this gets to you: Did you ever find a new source for ImunIvy? Bullard Co. is still in business, but it does not appear that they still manufacture it.
