The 1984 NEC states that breakers that operate vertically must be oriented so that they are on in the up position and off in the down position. (240-81)Pushmatic panels have no such “up / down” functions. Does it matter how they are mounted? I found one today upside down.
If the bottom circuit breaker is labeled as the “MAIN” and cannot be read I believe the the “panelboard” is up-side-down because the cabinet shows that the mounting hole is correct for the placement of a screw. I’ll bet that they did this because of the cable (is it an SE or SER?) was too short.
The bottom breaker was clearly labeled as “Main” - (it can’t be seen in the photo). The SE loops up from the meter mounted on the outside wall. Is the defect that the SE is too short or that the panelboard is upside down?
I am new here and still learning. I have a pushmatic panel in my home, and the individual breakers have a small window that shows either “on” or “off”. If the writing is upside down?
