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.
