Looking at a job that we have to finish... There is a combination meter socket/disconnect at one end of the lawn that had a 160 foot pipe run that we had to relocate for an addition. It had three lengths of 4/0 that I felt to be too small for the distance and no seperate ground, assuming the meter disconnect to be the actual service. I stepped it up to 3 250's AL and one #3 copper. Would I need rods at the house, and considering what was just said in the previous post, are they going to have that kind of problem if I don't bond the neutral and ground at the panel?
