b. Electrical testing. Electrical testing of the fault protection subsystem should be conducted every 24 months per NETA guidelines. (1) With neutral disconnected at first service disconnect, the resistance to ground should be at least one megohm. (New ground resistance testers on the market today do not require that the neutral conductor be disconnected.) (2) Perform spot check resistance measurements on power receptacles and stray current measurements on safety ground to insure that the ground terminals on the receptacles are properly grounded to the facility ground system and no currents are flowing on grounding conductor. (3) Measure for stray currents at obvious locations. (4) Perform resistance tests of a sample of bonds as described earlier in this chapter
