Insulation testing (perform, interpret, and evaluate insulation tests, including resistance, dielectric absorption, polarization index, and applied voltage withstand)

Inspection and maintenance of wires, cables, and buses. (Verify correct type and ratings for the installation and use. Confirm correct bending radius, spacing, support, environment, connections, connectors, and terminations.)

Cable testing. (Perform and interpret insulation resistance and dc applied-voltage withstand tests and cable and shield continuity tests. Applied voltage test by go/no-go and step-voltage methods. Record data in time versus leakage current.)
