Hello All!: Need a little help here. I am wanting to control a SSR (+12 vdc) placed in a standard ac wall outlet box to parallel a standard 120v ac SPST ac light switch. The application is in the US so I am inquiring about what is accepted practice in the US (i.e., the National Electric Code (NEC)). The NEC is really hard to deal with and I find very little in the way of clarity in its' dealing with mixed (low and high voltage) wiring. Any help here would be greatly appreciated! Thanks!
