Golden Pothos ZZ Plant Aglaonema AKA Chinese evergreen (I think Aglaonema is probably one of the very best low light plants).

The brown spots with yellow fringes on the leaves makes me suspect something bacterial. I've seen peppers get lesions and go soft on the same type of infected plants ... i'm well acquainted unfortunately. Personally i'd give it a shot of copper spray to prevent whatever it is from spreading. You can spray copper every week, and directly after rainstorms. But after a 3 or 4 weeks you should be good to go for the rest of the season, no need to spray all season long and get all that excess copper in your dirt. Check the link below for an example, there's a concentrate version which would need a sprayer, and a ready to use version. Here is a link that might be useful: Ortho Disease B Gone Copper

The box is 4" square and about 2" deep which is kind of crowded with that large receptacle and 4 very stiff wires. I may replace it with a 4x4x4 deep box if it's available. I don't see any stray strands of wire that could be touching the box, all the wires in there are #10 solid copper wire, and all bare copper except the ground is enclosed in the receptacle lug holes. The box isn't hot, and a test light lights up between the red wire slot and the white neutral slot and between the black wire slot and neutral. When tested with the power off there is no continuity between either hot wire slot and the ground slot, but there must be some contact somewhere between the neutral and ground because a multi-tester shows roughly 12-15K ohms resistance between those slots. Would that be because the ground and neutrals are joined in the breaker box? I can't see how they could be touching anywhere in the box or at the receptacle. I tried pugging in the dryer this morning a couple of times and there was no snap sound and no smut on the neutral blade, but nothing has been changed or messed with in the box since yesterday. I just wish I knew if it is safe to operate the dryer since my wife will be needing it Monday.

If life gives you lemons, pray they are Meyers. Based on the lack of a winged leaf petiole, I would guess some kind of lemon, maybe Meyer. It looks like your tree could use some good citrus fertilizer, and maybe water.
