is completely installed, inspected, and tested. All conductors must be connected and functional,

including the neutral. The voltage rating of the device and system must always be verified before

energizing the surge protective device.

· Any factory or on-site testing of power distribution equipment that exceeds the normal operating

voltage, such as high-potential insulation testing, or any other tests where the suppression

components will be subjected to voltages higher than their rated turn-on voltage must be performed

with the suppressor disconnected from the power source. The neutral connection at the SPD must

also be disconnected prior to performing high-potential testing and then reconnected upon

completion of the test.
