Running power to a well pump

Just bought a property. Very small "shack" that is basicly unlivable on the front of the property. There is a well for water about 100' away from the shack and power for the well comes from the shack.

Well, the shack is going away and a new house is going on the back of the property. The well will be about 175 feet from the new house. I need to run power from the temp power pole out to the well. What's the right way to do this? Oh, and it's a long story but the pipe to carry the water to the new home site is already in the ground.

- I assume I'm going to have to rent some sort of trench digger to put the cable in the ground.

- What type of cable do I have to use and given the length of the run, what guage?

- Do I have to run the cable inside any sort of pipe?

Thanks for all the help, believe me it's appreciated.

You'll need to provide pump specs to determine the cable size. Provide amps and recommended breaker size.

Gosh... why didn't I realize you would need that info. The data are as follows:
8 amps
20 amp breaker (why not a 15???)
#14 wire up to 300'

So I guess I have my wire size question answered. Oh, and now that I think of it, the distance to the well as well as the depth of the well (pump is at the bottom) need to be added to properly size the wire. I wasn't thinking of the well depth.

Now how should I run that cable underground?

I'll wait other more expert to give an answer but I would not go less than #12 over that distance.
Yes I would bury it.

"The data are as follows:"

One hardly ever sees the word "data" correctly followed by "are". You've made my day!
