I am hardwiring a transfer switch, instead of using their plug. I have cut a hole in the side and put in a cable clamp. I would like to remove the plug to create more room. That will leave a 2
1/4" hole. Can I put a piece of aluminum flashing over the hole, fastening with screws in the same holes that the plug was fastened with? I can't imagine why this should be a problem, but the code can be a bit odd at times. A plug would be easier, but I don't find any 2 1/4" ones.BTW, I posted last week about how to join my solid 10 cable to the switches' standed 12. My soldering iron wasn't big enough, and I couldn't find the recommended wire nuts. Well, I found I could solder some stranded 10 onto the end of the cable using a propane torch. The stranded 10 twists up nicely with the standed
12, and the extra wire makes everything easier. A torch is okay to use on wire, isn't it?
