Which risk increases significantly when over-sensitizing ground fault circuit breakers (GFCI)?

💡 Explanation

Nuisance tripping rises when GFCIs are too sensitive because variations in background leakage currents trigger the *differential current sensing* mechanism earlier than necessary; therefore, breakers trip without a true fault, rather than operating only during legitimate fault conditions.
