The floor sander left this at a job site. It's pretty
safe by flooring company standards. :roll: It's a 30
amp dryer cord with a 20 amp/250 volt twistlock. They
actually wired the twistlock correctly and used black
and red for hot and green wire for the ground. I guess
they never have to worry about the breaker tripping.

Bonus: can you spot something else that's wrong with
this setup?
