The dog bone isn't the problem. It causes the problem. It connects the same phase to two conductors in the cable running to the trailer with only one neutral. That isn't allowed. Each conductor with the same phase has to have it's own neutral. (I may have cited the wrong code section earlier)

Wouldn't National Electrical Code Article 366.20 prevent the use of such a dog bone device? 366.20 stipulates that only 1 conductor per phase can be run in a cable.
