I had a house trailer I dragged in to live in while I did it. I put my own box and shut off right on the pole so I didn't need to call them every time I did something. Its all up on poles here until the last pole. From there, from the 200 amp disconect it goes under ground for the last 120 feet. I put in the grey pvc also and then ran 3 thick black wires, about as thick as my thumb thru them. We were going electric heat at the time so I could get a transformer on the last pole here. The only way I could get it was if I was putting in electric heat and at big welder, Low and behold, I was, but didn't.... No voltage drop here...... Althought I had a squirrel jump on it once and short it out, big loud bang and a post tostie squirrel.... Pretty sure they told me I had to go heaver because it was underground. This was 25 years ago so its all vague. I was working 14 hours a day on a job and driving and hr each way so was short on patience. Just get-er done.....
I remember they wanted it all under ground but it would have been major bucks and I could not see it as the rest of the road was above ground. Even then it was 180 bucks per pole, 150 bucks per pole anchor and 240 per span of wire between each pole. But it all worked and still does so I guess I did it right. I remember the electricians on the job were pulling out the temp wires, all #12 stuff, like new and tossing in the dumpsters. You know what my house got wired with. That number 12 is a little stiff in some spots but it worked fine.
If the rocks here were fist size I'd be thrilled. Most here are huge and a major pain in the butt. I can dig with the backhoe for and hour and get a cup of dirt and 30 ton of boulders from the days of glaciers.....There are spots here without them, but not where I usually want to dig......LOL
