so this past winter unfortunately a tree went through the roof of my trailer. luckily for me it give me the excuse I’ve been looking for to build one myself. I’ll be using the old frame and building ontop of that. now to the point if I wanted to set it up so that I can plug it into a 30amp power supply but not necessarily run it off a battery or solar, what I want to know is if I install the plug do I need to connect it to a fuse box before running wires to install plugs for things like my phone, a fan or a heater among other things. and if that is the case does anyone have any suggestions on which boxes would work for what Ive described
