    Default Black and Red Insulated Conductors

    This probably isn't worth posting, but I just thought it was strange. Home was built in the mid 1950s and the service equipment is not original. Three-wire NM cable with ground. The black insulated conductor was wrapped with red tape and the red insulated conductor was wrapped with black tape.



    Huh?

    What comes to mind first is that someone was trying to keep phase colors the same, and missed the easy solution of swapping colors in the breakers.

    Representing A-Phase and B-Phase.
    Really does not matter on 240 volt single phase.
