Jimmy, back when my dad moved out of his house into a condo, we set up his shop in my garage. He was an accomplished wood worker but his was an electrical engineer as a profession. So we set up the wiring in the garage. I say we, his brains my brawn. His health was starting to fail at the time so it was great for both of us to work on this project together. Because I had young kids he was worried one of them might try out the equipment without supervision. He installed a key switch between the main circuit breaker and the sub box he installed. Long story but thought you might want to know about the key switch. With the key switch installed no one can turn on your equipment without your knowledge. Btw the electrical inspector was impressed.
