Quick veer off topic: working on my shed this weekend I had to move
an outlet to replace a stud. I pulled the disconnect lever on the
main subpanel. Put a meter on the outlet, it's still live. Really?
Lights are out, nothing works, but that outlet was hot. So I pulled
the fuse block out, looks exactly like that piece in the OPs photo,
now the circuit was dead. Just goes to show, always check.


So IOW you have two feeds to or in this shed?
