Should have added one more thing: People that bypass the government=20 inspections. How many people do you know that have done building=20 modifications, additions, and repairs without getting a legal permit to=20 do the work if required. And how many people have done work without=20 consulting a design professional to size components properly, and this=20 includes everything from steel beams to wire size and circuit protection=20 ratings. At the moment, I have a thread going with 2 friend electrical=20 engineers for a home project of adding a 220 volt 1 hp. motor, but it's=20 not a common install. Our area, at this time does not require a permit,=20 or have inspection on this type project, but I am ensuring that the=20 installation would meet the toughest inspection. After all it's my=20 safety, don't want to set the house on fire. :) On 9/8/2010 4:36 PM, Carl Denk wrote: > The owners many times, to save costs, do not want to pay the structural > engineer for site visits to inspect the construction.
