I posted a pic awhile back of this panel without the cover taken off. Could someone help explain a few things for me, this is the main panel, there are two hot conductors coming in from the back and looks like a 6 gauge bare copper coming in that connects to the neutral bus. That bare copper wire I thought was the equipment grounding conductor but where’s the neutral? Is the copper wire the neutral but then we’re is there equipment grounding conductor? The bigger wire dropping straight down from the top is just to the dryer, and its a main lug only panel so no main disconnect, fewer than 6 movements to disconnect , and on the sec there’s just two sets bc it’s a duplex.
