Question: Can an AFCI/RCCB breaker be used in place of a GFCI breaker, say for example near a sink?? A fellow co worker stated there wasn't a need to order GFCI receptacles/breakers because we already had AFCI or RCCB (merlin Gerin) breakers in our load centers. Looked into thru Schneider electrics website, but can't get a good answer. Thanks to all replys.
No, an AFCI/RCCB breaker cannot be used in place of a GFCI breaker for sink protection.Differences between AFCI, RCCB, and GFCI
AFCI (Arc-Fault Circuit Interrupter)
Detects and interrupts electrical arc faults, which can cause fires.
RCCB (Residual Current Circuit Breaker)
Detects and interrupts ground fault currents, which can cause electric shocks.*
GFCI (Ground Fault Circuit Interrupter)
Detects and interrupts both ground fault currents and arc faults. GFCIs are specifically designed for use in wet or damp locations, such as near sinks.
2020 NEC Requirements
The National Electrical Code (NEC) requires GFCI protection for all 120-volt, 15- and 20-amp receptacles within 6 feet of wet or damp locations, such as sinks.
Merlin Gerin RCCBs
Schneider Electric's Merlin Gerin RCCBs are designed for ground fault protection only. They do not provide arc fault protection or the specific features required for sink protection by GFCIs.
Conclusion
While AFCI/RCCB breakers provide important protection against electrical faults, they
do not substitute for GFCI protection in wet or damp locations, such as near sinks. GFCIs are essential for these areas to prevent electric shocks. Flag for review
