Ground fault breakers monitor the current on the neutral wire flowing back to the neutral bar, a 4 to 6mA difference will trip the breaker, Shunt trip breakers on the other hand can be tripped remotely from some other type of switch or location. In industrial applications it is used to shut power off in an emergency situation, when access to an electrical panel may denied.
Check the earth fault trip off set limit of the ACB. It may be too low.
Neutral, by definition, is grounded at the distribution panel, and also at the distribution pole. That is how the hot to ground voltages are prevented from exceeding their normal voltage and encroaching on truly lethal voltages, such as 7.6kV in a typical US 13.2kV system, in a wye configuration.Note: and this is critical, do not depend on the fact that neutral is grounded and consider that it is the same as protective earth ground. It is not. Protective earth ground is a different wire.
Yes, the electrical code requires a ground fault breaker for your hot tub.
Ground Fault Circuit Interrupter (GFCI).
Ground fault relays sense ground faults in the circuit and trigger a circuit breaker to trip off
The GFCI (Ground Fault Circuit Interrupter) can trip with no load due to internal issues or a ground fault in the circuit. This can happen if there is a problem with the wiring or if the GFCI itself is faulty.
A GFCI (Ground Fault Circuit Interrupter) is designed to trip within milliseconds when it detects a fault, such as a ground fault or leakage current. This rapid response helps to protect against electric shock by quickly shutting off power.
The GFCI (Ground Fault Circuit Interrupter) may trip when it rains because water can create a path for electricity to flow to the ground, causing a ground fault. This triggers the GFCI to shut off power to prevent electric shock or fire hazards.
A Ground Fault Circuit Interrupter (GFCI) trips when it detects an imbalance in the electrical current, which could be caused by a ground fault, overloading, or a short circuit.
A ground fault circuit interrupter (GFCI) will trip when it detects an imbalance in the electrical current flowing through it. This can happen when there is a fault current, such as when electricity leaks to the ground or encounters a path of least resistance. The GFCI is designed to quickly shut off power in these situations to prevent electric shock or fire hazards.
If the fault is a direct short to ground, the fault current can be high enough to trip the upstream protection.
A ground fault circuit interrupter or rcd trips when the is leakage current to ground In no fault condition the active and neutral conductor emf's cancel each other out in ground fault condition the emf's become unbalanced resulting in a small voltage being inducted into a toroidal coil which activates a internal trip relay resulting in disconnection of supply domestic rcd's are generaly set to trip at 30ma to ground

A GFCI outlet will trip when it detects a ground fault, not when the current is simply reduced or shut off. The purpose of the GFCI outlet is to quickly shut off power when it senses a potential electrical hazard, such as a ground fault or leakage.
Yes, rodent damage to Romex can cause a ground fault circuit interrupter (GFCI) to trip. Rodent chewing on the wiring can expose the copper inside, leading to a ground fault. When the exposed wire contacts a grounded surface or another wire, the GFCI will trip to prevent electric shock or fire hazard.
A Ground Fault Circuit Interrupter (GFCI) may trip if there is a leakage of electrical current, which could be caused by a ground fault, short circuit, or overload. This safety feature helps prevent electric shocks and fires by quickly cutting off power when it detects abnormal current flow.
