Visual/Mechanical: Verify nameplate matches project specifications, inspect the installation and appropriate clearances, verify individual ground leads on each device, check stroke counter if present.

Electrical: Measure resistance through bolted electrical connections and grounding connections using low-resistance ohmmeter and perform insulation resistance test. Watt-loss testing is optional per NETA but I would recommended if available. Test voltages for electrical tests will depend on the voltage class of the arrester.
