There was a lot of unused space at the bottom of the breaker panel that was completely empty. (All the circuits go out the top of the panel into the attic, and nothing was occupying the space at the bottom of the panel.) It’s a really clean job, looks neat, and is 100% reversible… But I’m pretty sure it’s against the electrical code.
It seems to be working well. If anyone knows of a reason why I really shouldn’t do it that way, I’d appreciate it if you’d persuade me before I cause a fire or something.
I’m not sure I’m going to keep it that way for long. I’m keeping an eye out for a nice looking electrical box that I can mount next to the breaker panel. I’ll mount the EZSwitch30 in the box, and run the 10/3 Romex behind the wall into the breaker panel, and hopefully prevent myself from frustration later if an inspector should have a gander into the panel.
