Does current or resistance cause breakers to trip?
Excessive current is what causes circuit breakers to trip. When the current in a circuit exceeds the rating of the breaker, it trips to prevent overheating and potential fire hazards. Resistance itself does not cause breakers to trip, but it influences the amount of current flowing in a circuit.
How is the relay effecting the bimetallic strip of circuit breaker?
The relay controls the flow of current through the circuit breaker by responding to an overcurrent situation. When the relay detects an overcurrent, it triggers the circuit breaker to open, which releases the tension on the bimetallic strip inside. This causes the bimetallic strip to bend and disconnect the circuit, effectively breaking the flow of electricity to prevent damage or hazards.
What causes a electric current in a electric circuit?
Voltage causes current to flow in an electric circuit.
Can circuit breakers help to prevent building fires?
Breakers limit the current on the conductor to a safe level, too many appliances plugged in. You trip a breaker, hopefully you then transfer load to another circuit. Breakers use two different methods to accomplish this, one uses a bimetallic strip and the current passes directly through, too high a current causes the strip to deflect. It acts on a mechanism much like the sear in a guns trigger, the deflection pulls the trigger causing a spring to open the contacts and turn off the circuit. Another type is thermal magnetic, current passing through the breaker causes a magnetic field to act on a coil tripping the breaker. When breakers are wired and work properly they prevent fires!Bending metal opens a switch

What causes a circuit breaker to trip?
A circuit breaker trips when there is an overload of electrical current flowing through the circuit, causing it to heat up and trip the breaker to prevent damage or fire.
What trips a circuit breaker and causes it to shut off the flow of electricity?
A circuit breaker trips and shuts off the flow of electricity when there is an overload of current or a short circuit in the electrical circuit.
What would cause a circuit breaker to trip?
A circuit breaker trips when there is an overload of electrical current flowing through the circuit, a short circuit, or a ground fault. This causes the circuit breaker to automatically shut off to prevent damage or fire.
High voltage will trip a circuit breaker?
A higher voltage means that a higher current will flow in the same load. It is the current that causes the breaker to trip.
How does a circuit breaker trip and what causes it to do so?
A circuit breaker trips when there is an overload of electrical current flowing through it. This can happen when too many devices are plugged into the circuit or if there is a short circuit. When the current exceeds the breaker's capacity, it automatically shuts off to prevent overheating and potential fires.
Circuit breakers are used for what?
Circuit breakers prevent excessive current from flowing in the circuit by "tripping" when the current exceeds the circuit breaker rating. This causes the current to be cut off, and is used to protect the wiring as well as the appliances.

How does a breaker trip and what causes it to do so?

What are the common causes and solutions for a breaker lock out situation?
Common causes of a breaker lockout situation include overloading the circuit, a short circuit, or a faulty breaker. Solutions may include resetting the breaker, redistributing the electrical load, or replacing the faulty breaker.
Is An open in the main line of a parallel circuit causes all individual branch currents to be zero?
Yes, an open in main line of a parallel circuit will effect the entire circuit current and make the whole circuit current zero
What causes a current in an electric circuit?
Voltage causes current to flow in an electric circuit.
What causes circuit breaker to trip even when it's properly rated?
A circuit breaker is dual function. The only time it will trip is if it senses a fault current that is rated higher than the breaker rating (short circuit). The other trip condition is if the circuit is overloaded and is drawing a current higher than the breaker rating. On breakers that protect motor feeders the breaker has to be rated 250% higher than the motors full load amperage. If the breaker has lots of use and is used for a switch being manually turned off and on will weaken the trip value of the breaker. If you have access to, or know an electrician, a clamp on amp meter on the conductor that the breaker feeds will tell you what is happening. Clamp the line and turn on the load to see exactly what the current is. If, like you say, the breaker is properly rated and the current is within the breaker limits then change out the breaker for a new one.
