I can't help you with the pricing of the wire. As far as the 220 to 110 goes, what I have usually seen if the utility has 220 volts at the pole, is that there are three wires. One is a neutral, which is tied to ground (0 volts) at the main distribution box. The other two are each 110 volts from the neutral and are 220 volts from each other. The distribution box is set up so that if you plug a circuit breaker for a 110 volt circuit into it the circuit is connected to the neutral and one of the 110 volt legs (a 110 volt output) and if you plug a circuit breaker for a 220 volt circuit into it the circuit is connected to each of the 110 volt legs (a 220 volt output). So there is no need for a transformer. I?m curious what kind of load this house is going to have with a #10 feed, and how far it is from the utility pole?

How far is your house from the utility pole?

Wow, that's far (see above post #3). You can google electrical voltage drop to get a better understanding of what you are up against.about 1500 ft.

A few examples of the maximum distance using #10 wire while maintaing a voltage drop of 3% or less.

A maximum distance of 343.076 feet will limit the voltage drop to 3% or less with a #10 Copper conductor delivering 5.0 amps on a 120 volt system.

A maximum distance of 171.538 feet will limit the voltage drop to 3% or less with a #10 Copper conductor delivering 10.0 amps on a 120 volt system

For Engineering Information Only:

30.0 Amps Rated ampacity of selected conductor

1.1417 Ohms Resistance (Ohms per 1000 feet)

0.05 Ohms Reactance (Ohms per 1000 feet)

3.5999999999999996 volts maximum allowable voltage drop at 3%

0.9 Power Factor

Not using #10 wire. I did a quick calculation using one of the online programs. You will have a 12% voltage drop with a 10 amp load using #10 wire. So feeding a transformer with 180 volts will not give you an output of 120 volts.if i bring 220 to house and reduce it to110 will it give me full110? i realize the220 will drop quite a bit but will i still have enough to get 110?

I think that might be cheaper!

although ccccccccccccc has a pretty good idea....lol

Wouldn't that be a voltage regulator?
