I am adding an audio amplifier that requires 60 amps of protection. I have never opened the panel of this boat, but I do electrical work (solar) for a living and I want to do it myself to make sure it is done properly. I will need to use heavy guage wire (#4) and am not sure what type of connectors the panel breakers use. There is currently a breaker labeled "spare" that I plan to use. Does anyone have pictures of the back of the panel? I am 2 hours from my boat and at least want a chance at bringing the right parts. Also, it seems like when I pull the cover off of the panel, the entire panel may come with it, unlike a house panel that has a cover. Is that correct?
