I'm wondering for you market vets out there, if you're new to a store and can't find a breaker (evap motor replacement, etc.) and don't have all day to hunt around to 10 different panels, what do you do? I was recently told to either follow the wire to a j box and disconnect there, or...ground the hot wire. I'm a little reluctant to ground a hot wire for a lot of reasons, mostly because if the breaker that serves the circuit in quesiton fails, I may take out that whole sub panel...or worse. But I'm just wondering what you vets do in this case.
