ITO, That's exactly my point. What I described is not temporary, it is permanent. Also, what I described in my post(though I left out this detail)is an underground service. An over-head service would be a safety issue for the brick, roofing and siding contractors. I do not see how an underground service installed as I described would present any additional safety issues. Buildings are remodeled, resided, repainted, reroofed and the brick repointed all the time without the service being required to be de-energized when it is an underground fed service. I don't see any need for it to be.
