If you're looking for a cost effective way to add some loads (a hot tub or sauna maybe?) but you don't quite have the capacity, span devices are a great compromise to spread the loads and prioritize your equipment power allotment. Saving you $$ on a pricey service upgrade!
Span smart panels & devices allow you to see and control everything going on electrically with your home!
