CONDITION
The new DCA-8000 Diagnostic Charger may cause your facility’s Ground Fault Circuit Interrupter
(GFCI) breaker to trip. A GFCI breaker can be tripped for various reasons, one of the reasons may be
related to the DCA-8000. We are investigating this issue to determine the root cause.
Other reasons the GFCI breaker may trip
 Circuit demand is too high for GFCI rating
 Worn out GFCI internal contacts
 Improper installation or wiring of GFCI breaker
RECOMMENDATIONS
If the DCA-8000 is causing the GFCI breakers to trip on separate circuits, protected by different GFCI
breakers, then the DCA-8000 might be related to this issue.
Please confirm all other loads are disconnected from the GFCI breaker when testing DCA-8000, if the
GFCI breaker continues to trip, please contact the SST Customer Service Team by calling 1 (800)
933-8335 to report the issue.
If the DCA-8000 is determined to be the cause of the GFCI breaker tripping issue, an interim
countermeasure DCA-8000 will be exchanged.
