This moment was sweet. Jessy reminded me to turn the water on, but all-in-all, the wiring and panel work only took 2 hours. I didn’t have much doubt in the wiring or the energizing of the breaker, but in the end, anytime you wire something without a dedicated neutral, it’s basically like wiring a magical box and hoping it works. Anyway, the green light is the system light and the 2 red lights indicate that it’s working, so up next is a hot shower pic.
