5.2.1 Impressed Current Systems

Equipment used for impressed current systems must be served by a dedicated and clearly marked electrical circuit that remains energized at all times.  


Equipment must maintain an instant-off reading of at least 850 millivolts and 100 millivolt or greater polarization shift from the instant-off reading.  


Impressed current equipment must be equipped with an ammeter and hour meter that totals the number of hours during which electric current flows through the system.
