What causes an incandescent bulb to explode when burnt out and in so doing trips the circuit breaker?

You or someone knocked over the lamp - which bursted.The larger bulb filament holders were violently forced against each other. The contact with each other caused a shorted circuit and that opened the breaker.

What causes the main breaker to trip from a fault current from a twenty amp branch circuit?
If the fault was on the 20 amp branch circuit, the branch circuit breaker should have tripped, not the main breaker. Call a qualified electrician to check out your wiring.
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.
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.
What causes the bulb to light in closed circuit?
Energy flowing through the filament. In a traditional incandescent bulb most of the energy is radiated as heat which is why they are viewed as inefficient.

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.
How do you repair short circuit when all appliances are tested to work properly?
If the appliances all test out and are found to have no short circuits in them then the next step is to check the supply conductors that feed the appliances. This can be easily done by unplugging the appliances and turn on its circuit breaker. When voltage to the appliance circuit causes the breaker to trip. this is the circuit with a fault on it. The most likely place is at the receptacle where the appliance plugs into the power supply. Turn the circuit off at the breaker and inspect the receptacle. If it looks suspicious change it out with a new one.
How does a circuit breaker help protect against short circuits and circuit overloads?
Quite simply, so you don't put too much current on the wires than they can handle. They also provide protection from 'ground faults', which is when the 'hot' and neutral wires touch. This causes a spike of current (because the resistance drops to near zero) and the breaker senses that too, or it should when it functions properly.
What is function of damping relay in circuit breaker?
The anti-pumping relay is a device in circuit-breaker whose function is to prevent multiple breaker closures. For instance, if the operator gives the closing command to the breaker by pressing the close button and the breaker closes. However, a fault in the system causes the breaker to trip. Since the close command is still in the pressed condition, there is a chance of the breaker closing again and being tripped by the relay multiple times. This can damage the closing mechanism of the breaker. The anti-pumping relay prevents this by ensuring that the breaker closes only once for one close command from the control panel.
Will cutler hammer breaker fit GE panel?
Cutler - Hammer manufactures two types of residential circuit breaker for the US. Type CH and type BR. The type BR will fit into most GE panels. It is probably a bad idea to use any other circuit breaker except the type listed on the label of the circuit breaker panel. GE panels require you to use GE circuit breakers. Using any other brand may put you at risk for liability if the installation fails and causes harm or damage.
What causes electrical overloads?
Electrical overloads are caused by the load amperage increasing above what it should normally be. On a motor load this could be a request for the motor to do more work than the motor is capable of, working outside of its HP rating. In a house circuit an overload is created by plugging more devices into the circuit than the circuit breaker can handle. Again the load current will be higher than the circuit will allow and the circuit will open by the tripping of the breaker.
You are having to reset your electric water heater breaker daily?
Likely one of the two electric elements is going out which creates very high resistance in the circuit and therefore draws very high current (amps) and causes the breaker to trip.
