Can you put emergency power circuits in the same junction box as normal power circuits? In general, you can't do that, but there are exceptions. Can you.
I noticed that Relay Component can actually spread power just like junction box, but doesn't suffer from EMP or overload damage. Any reason not to rewire power to relay component completely, except maybe some aesthetics and my own time? Same question about Wi-Fi: any reason to using junction box over using Wi-Fi to transmit signals? However, I can't use a double pole switch because I would have normal power and emergency power in the same box, and there is no exception for switches. Same problem with a relay. .
