This is a picture of a Square-D "All-in-1" service panel. As you can see, it is impossible to mount this panel so that all the breakers will have "down" as the "off" position.

It doesn't appear very old. When did the NEC first mandate that "down" was "off?" When did they stop making these panels?

Is it possible this panel was made for Canada?

I would have thought the up is on code has been around longer than the panel in the picture.

Regardless of how it is made I would say this is a direct violation 240.81 and no breakers should have been installed in the top row.

I've been reading through sections of the 1971 NEC that I acquired, and have actually just reached 240 on overcurrent protection.

The current NEC's 240.80 thru 240.82 seem to have all been covered under 240-25 in 1971.

240-25(c) says that breakers must indicate whether they are in the open or closed position, but I can't see anything else about orientation.
