200 feet is a pretty good distance. i recently did what was final length i want to say 150 feet.
i ran from house to shed.
--electrical pole by road,
--to house to 200amp meter,
--then to 200amp main panel inside house, that has multi break locations for outlets and lights, ac in the house plus... (see next line)
--i then have a 100 amp break in it.
--then ran 150 feet to shed
--in shed i have another break panel that has a main 100amp break in it.
--from here i ran all the lights and outlets to the breaker panel in the shed.
for you....
--electrical pole by road
--to utility pole in yard
--200amp meter
--200amp disconnect
--200amp main panel (lug, or how ever you want to state it)on the utilty pole. with min of 2 spots on it. 1 breaker spot 100amps for house, and another spot 100amps for shed. i should correct that i think you also need 200amp main breaker in this panel / lug. ((someone correct me plz))
--from one of the 100amp breakers run wires that can handle 100amps to house.
at later date, run from the other 100amp breaker. on pole with 100amp or better rated wires to shed. and install 100amp panel in the shed.
====================
for me, i found out that copper vs aluminum was just a few bucks, when i say few under 40 bucks. aluminum you need to use a bigger size wire than copper. and for me that ment an easier pull of wires ((had a few bends i had to pull wire through. i think the difference actually came out to be 3 to 10 bucks final difference once figuring out cost of pipe and fittings. between using copper vs aluminum pipe. and if figuring out rating i think for me the copper came out to be less voltage drop vs aluminum due to ratings of the wire i was able to get at a local supply warehouse were a tad different.
((note)) call local supply warehouses. menards, lowes, homedepot cost was almost 2 to 3 times more!! savings of a couple hundred bucks!! for same type of wire. i also passed on the multi combo wire. it was like a buck more per foot than buying everything together in a combo single wire strand.
it was fairly simple to pull wire through a pipe. i did the initial digging of trench putting in the pipe with sand for me (some rough dirt that was going back in)
the wire i bought was all individual strands of wire. and not all combined and woven together. into a single long wire. so i dragged all the wires out side. and unrolled them all. i went back with eletrical tape and every 3 feet or so. i put a piece a tape a couple times around all the wires. clear down the entire length. i then wound all the wire back up. and took back into the shed.
from there, i got some light weight string, (nylon string) and tied a rag onto it. then went back into house hooked up shop vac with a peice of tape to end of pipe. and sucked string through. once that was through, i used i want to say a #12 stranded copper wire and pulled it through using the nylon rope. i then tied the #12 wire to the bundle of wires i had all taped up. i then got a large bowl out and emptied a bottle of "wire pulling" lube into bowl. my mom wiped the wire down as i pulled the wire through the pipe. within a short time it was all pulled through without to much fuss.
the actual fuss i had. was inside the house. and trying to route the wire through some 90's ((i had to cut a couple 90's out and install some wire pulling 90's in ((the 90's the sides of them unscrew off to allow access to the wire inside of the 90 so you can pull / push the wires through the 90)). so i could route the wire to the main panel in the house.
