For each type of device used to accomplish electrical isolation, describe the specific testing performed to demonstrate that the device is acceptable for its application(s).

This description should include elementary diaqrams where necessary to indicate the test confiquration and how the maximum credible faults were applied to the devices.

(2)

Provide data tn verify that the maximum credible faults applied during the test were the maximum voltage/current to which the device could be

exposed, and define how the maximum voltaqe/current was determined.

(3)

Provide data to verify that the maximum credible fault was applied to the output of the device in the transverse mode (between signal and return) and that other faults were considered (i.e.,

open and short curcuits).

(4)

Define the pass/fail acceptance criteria for each type of device.

(5)

Confirm that the isolation devices comply with the environmental qualifications (10 CFR 50.49) and with the seismic qualifications which were the basis for plant licensinq.
