I sold a hot tub that was on my property when I purchased it. There is a 240V sub-panel that powered the hot tub and it has one double-pole breaker.
With the hot tub going away, what should I be doing with this sub-panel since I'm left with no load on it.
Should I just switch the single breaker off in the sub-panel? Should I also switch off the breaker at the main panel that feeds the sub-panel? Or should I be removing the breaker at the main panel altogether?
