I take pride in every connection I make and it is sad to see that evidently some do not. Most true electricans do great work. The poor quality work is probably most likly done by people that the elec. I'' mention it. As for homeowners, like I mentioned before, many do do great work.
Many homeowners are very knowlagable and can add can do most home wiring jobs.
Some just need a little help on a particular question and this forum is a great way to get opinions from qualified people. This is a great forum and I thank everyone who answers questions from everyone. After all, it is their house. Electricans are under pressure to do a job quickly and many times they cut corners. Who knows if they file the ends of conduit after they cut it.
