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.
