I'm assuming that the oversized-looking single pole breaker in there is a GFCI, in which case there should be a line neutral (probably that curly white wire) and a load neutral, also white (I hope). But there are definitely colored wires on the neutral buss. Can anyone see the service conductor for the neutral in here, along with the two hot legs? I can see where it's supposed to be, but it doesn't look like it's there.
For this little box to be capable of holding six SP breakers, it sure seems awful small and tight.
Lots of deterioration going on in there from exposure to the elements, natural and man-made.
