Summary
An ROV supervisor contacted a conductor in the wrong transformer cabinet during fault finding, suffering an electric shock and hand burn. The alternate system received 40V DC despite its breakers being off and potentially held high-voltage capacitive energy. Lessons address isolation, cabinet access, system familiarisation and testing before touch.
