3am might be a good idea if it was isolated, but it's right next to a house and that might not be good for the neighbors to get woke up that early. I have pretty much tried to get my plan together before I get up there, but there's always those unexpected things. I see I've got a heat duct to get by, and the pitch of the roof to either get a (2") 90 or 45 by, and (2) top plates to get a 2" hole through for the pipe, a sheet rock wall to cut for a 30/40 200 amp panel, (1) 4 gang switch box to move, run a spare 1 1/2" conduit for future use, and drive 2 grd. rods. and clean up the mess and try not to come out the side of the sheet rock when drilling my holes down the wall. Other than that, everything should go fine:) Oh yes, and swing the existing meter and riser over so I can hook back up temporarily after I'm through. "Piece of cake"
