This was a 240 volt, single phase circuit, with black, white and green wires. Black and white are hot, green is ground, is the "normal" way to wire it.

This guy had black and green hot, white ground.

I wondered why that damned box kept shocking me....

If it’s commercial and thus done as wires in flex or BX as opposed to Romex, B-phase should be something other than white. NEC 200-7

I meant to add that red is the usual color for B-phase in 240.
