HV-M1 · High voltage fundamentals · HV-M1-A Definitions, certification, hazards and the arrangement of marine HV systems.

Independent study. xplor is not an accredited training provider and awards no certificate or Certificate of Competency. The MCA High Voltage limitation can only be removed by completing an MCA-approved HV course (or, at operational level on revalidation, the qualifying HV sea service), and this material does not authorise anyone to switch, isolate or work on HV equipment.
