Of course there is a circuit breaker on the switch panel itself for the live well, but there is another fuse panel under the electronics pop up, actually behind the AC/DC panel over the aft cabin access passageway. (6 screws) I currently have mine open, blew a fuse on the trim tabs, but don't remember if there is a live well fuse. It is easy to check power at the live well pump with a meter. You have to look way up high above the main DC bus bar for the accessory fuse panel. Mine has the plastic cover over it, BlueSea brand if I remember correctly. I can go out and check mine on Sunday if you still need to know, since I have it open. Turns out my trim tab problem was the ES2000 rocker switch. Bennett sent me a replacement under warranty. Good Luck
