Looking back to the original OP question, I would almost suspect the blue wire would be from the converter, if in fact you originally had a 40 amp breaker in the box. The breaker appears to have been removed and the wires to it were spliced together and taped.

THIS is the best theory I've heard yet. Thank you for this. Duh, this wire is right in front of me! :laughing: I will need to do some voltage tests once I get 120v up and running again.
