Pipemaster,
If you are a contractor and are not concerned about being sued, you are either very good at what you do, very naive, or just don't care. If you are a contractor in a courtroom you are asumed to be a criminal. I was called as a witness in a trial once, and even then was treated like a crminal, and I was just a witness. Sure, there are some "professionals" that give the trade a bad name, and there are some DIY's that do excellent work, but in each case they are the exception and not the rule. I proctor the exam for DIY's that wish to do their own work in our area. The average score on a multiple choice test is about 40%. Keep in mind you should be able to score a 25% by guessing and not even looking at the questions. One of the questions is what color insulation is used on the grounded conductor? One of the choices is white or gray, and another choice is green. About 75% of the DIY's taking the test choose green. How can you possibly do acceptable work when you don't know the difference between a grounding and grounded conductor?
Let the DIY's go somewhere else for advice, there are plenty of people that think they are experts that will be glad to give them bad information. Many of them would ignore good code-based advice because it may add a few dollar's to the cost of the job.
I enjoy working on my own vehicles and back in the day, I was an ASE Certified mechanic. I know what I can do, and what I can't or shouldn't attempt. If I attempted a job that was beyond my ability, I don't think I would expect a profesional mechanic to tell me how to resolve the issue for free. If you are expert enough to do your own electrical work, you should be expert enough to refer to the code for basic informatioon.
