Exactly Don, you start with an amp clamp, only to find most of the circuits are at 90-110% of rated load. I find many resturaunts are like this. 18 - 22A on 20A circuits. You tell the customer about it, and they say, "well its been like that for years, how come it is just now popping?" And some places where ambient temps will just cook the insulation until it is dry and brittle over time. You go up to add a conduit for new circuits and find that its like an oven up near a cieling where the rest are run next to the tin roof. Or conduits on a roof covered in black roofing tar.
