A breaker will keep tripping until the fault that caused it to trip is corrected. That's what it is designed to do. There's either a circuit overload or a short circuit. How fast the breaker trips can indicate how overloaded it is. If you are very close to the rating of the breaker you can actually trip it over time. If you are definitely over the breaker will usually trip instantly. If there is a short circuit you can usually tell that by how violently the breaker trips. If you have conduit you can hear the wires banging around in the pipe. A frequently tripping breaker may also be faulty and need to be replaced - breakers are designed to fail by tripping prematurely rather than by not tripping at all, as this is much safer. This is very often the case for breakers that trip at seemingly random intervals, often when very little load is being drawn.

If live is kept open could it trip circuit breaker by connecting neutral to ground?
I would think not. However, if live were to come into contact with either the ground, or the neutral or both, this would cause a breaker to trip.
What would cause a circuit breaker heating element to trip off?
There are two conditions that would cause a breaker to trip off. One is an overload of the circuit and the other is a short circuit on the circuit. The heating element within the breaker is what monitors for circuit overloads.
Can a thermostat cause a breaker to trip?
If it is a line thermostat and it is connected across the line instead of in series with the load then yes it will trip the breaker.
What is transfer trip protection scheme?
A scheme where a signal is sent to to a remote location to cause a trip. An example could be a breaker failure scheme. When the breaker is told to trip, and fails to do so, fiber communications could be used to transmit a trip signal from the local substation to the substation the next bus out to cause that breaker to trip.
What can a loosely connected electrical wire in a breaker panel cause?
A short, which will trip the main breaker.
Can you put a 20amp water pump and a 30 amp water heater on a 50amp breaker?
No, they each need their own breaker of the right amp. Neither of them would cause the breaker to trip if there was a problem.
What may cause breaker instantaneously trip?
A breaker trips when its rated current has either been slightly exceeded over a period of time or grossly exceeded instantaneously.
Will cobwebs trip a breaker?
No, cobwebs alone will not trip a breaker. Breakers are designed to protect against overloading and short circuits, not cobwebs. However, if the cobwebs accumulate and cause insulation damage, it could potentially cause an electrical issue that may trip the breaker. Regular cleaning and maintenance can help prevent this.
Would a slight rise in the kva cause a 2000 amp gfci breaker to trip?
A circuit breaker trips when the current exceeds the rated trip current. Usually the trip current should be at least 25% more than the maximum expected load current.
Whatcould cause a sq d arc breaker to trip when aregular breaker doesn't?
The neutral is in contact with the ground at some point of the circuit.
If a shunt trip occurs does breaker go to off or trip position?
the breaker goes to trip position
What happens when a 20amp device connects to a 30amp receptacle and the power supply fails - will it trip the breaker?
Assuming you are referring to the power supply failing in your 20A device, it could cause the 30A breaker protecting the receptacle to trip. It depends on the mode of failure. It is easy to imagine a condition where a short in the power supply could cause a current in excess of 30A to flow to the device and trip the breaker.
