Primary Injection Circuit Breaker Tester
PI-5000 - ETI Precision (Electrical Test Instruments, Inc.)
The PI-5000 is composed of the PI2500 and the AUX-5000 auxiliary output unit, which when combined gives the unit the capability of testing 4000 ampere breakers, with essentially the same specifications as the proven PI-4000B. The auxiliary unit is smaller than the PI2500, so it can also be maneuvered easily in tight spaces, or lowered into shafts and manholes that would not be possible with a larger single piece unit.
