It sure looks like someone tapped off that 240 plug with some #12- maybe for 120? Would be kind of silly with that receptacle right next to it!
With the use of the LB, pipe, etc, I think we can assume this was done by someone in the maintenance department- and not some restless production guy.
That "somebody" really needs to be fired- NOW. Reasons:
1.) Too many amps on that #12;
2.) Bootleg neutral / parallel paths; and,
3.) General disregard, or knowledge, of the proper way to do this.
