Loadcenter is a common tern used in the field and we understand that, but the term panelboard and cabinet are defined in Article 100. I did not take the picture and called attention to it to address the subject in 110.12(C).
I'd be more concerned with all the three wire circuits that appear to have both wires tied to the same side of the line thereby overloading the neutral in each circuit.
Wait a minute, just noticed something. Is that bottom-right hand two-pole CB rated for aluminum wiring? If it's not, call 9-1-1 for a heads up! But then again, maybe the painter tryed applying gloss to fool us all?????
Is there anyone on board who knows how to fly a plane?
