I learn so much every time we do work on our house. The more I learn the more I realize what shoddy work many people do. When we added our bathrooms 8 years ago we paid the electrician a lot of money to put in a new main panel and do other wiring. The left side of the picture is part of the crap that he did and the right side of the picture is our new proper subpanel. There will be no wire nuts in the new subpanel!
