Looking at this, I gotta wonder if there's someone adding circuits someplace & just temped in a couple in the process... While it would've saved on some wasted time termination things twice.. If I'm working on a house, the cover is going back on anything thats hot before I leave... If it's someplace where kids are around, I'll bring someone to stand next to the panel & say "Don't touch that!" while I work [Linked Image]
As far as the blue neutrals, it looks like someone brought a limited number of #12 THHN colors when they installed the QO inplace of what was probably old fuses in the can to the right.. Hey! You all know where copper prices are going? Whats cheaper? carry a rainbow of wire or a rainbow of phase tape? [Linked Image] (Yeah yeah, I know! [Linked Image] ) Anyways I think the blue & white wire contrasting with the gray panel can looks marvy! [Linked Image]
