I have cut back for the same reason as the OP. The threads are repetitive and argumentative for no reason other than someone has too much time on their hands and loaded with mis-information. An opinion on what truck is best, what caulk to use, etc, is one thing, but when you have some armchair electrician who has never picked up a VOM asserting how a 50A service works and how to troubleshoot it, that's over the top, not to mention potentially lethal. Then there is the 3rd and 4th party information that someone read on the Internet. It has to be right because it was on the Internet, right? Throw in a couple of formulas from retired engineers that you have to be a math major to understand and the thread goes to hell in a handbasket pretty quick because no one wants to be wrong even when they're wrong. I'm done also.
