Why will too many electrical devices operating at one time after blow a fuse or trip a circuit breaker?

The load exceeds the limit of the breaker or fuse. For example a 20 amp breaker on a 120 volt circuit will handle 2400 watts. Exceed that wattage and the breaker will trip or the fuse will blow.

What device can break an electric circuit?
There are 2 different types of these devices: circuit breakers (which can be reset after the problem is fixed) and fuses (which must be replaced after the problem is fixed).
What things need a electrical circuit?
Electrical devices need an electrical circuit.
What is the purpose of a branch circuit?
To supply power to all electrical devices in a house, apartment, condominium, etc. A branch circuit is connected to the circuit breaker panel which is usually found in a closet or a cupboard
Can a circuit breaker be tripped by using 20 amp sockets instead of 15 amp sockets?
A circuit breaker protects the wires that the devices are connected to. If the devices that are connected to the circuit are 20 amps the wire size should be #12 wire fed from a 20 amp breaker. This breaker should not trip unless the circuit is overloaded or a fault occurs on the circuit. If the devices that are connected to the circuit are15 amps the wire size should be #14 wire fed from a15 amp breaker. This breaker should not trip unless the circuit is overloaded or a fault occurs on the circuit. Putting 20 amp sockets on this 15 amp circuit will work but the circuit is limited to the amount of load that can be plugged in. You will not get the full capacity of the 20 socket because the breaker will trip at 15 amps.
The electrical Breaker will not reset?
To reset a breaker move the handle completely to the off position. If it had tripped you will feel a little resistance as it goes to the off position. If this doesn't restore the power the breaker is either bad and in need of replacement, or there is a persistent fault in the circuit causing the breaker to immediately re-trip. Breakers are safety devices.
What devices do not protect you from electrical fires?
circuit breaker
What electrical devices can be reset and used again?
An electrical safety device that can be reset and used again fits the description of an electrical circuit breaker.

Which type of circuit is favored for operating several electrical devices each independently of other series or parallel?
parallel circuit .

How do you trip electrical circuit breaker in normal working condition?
One way is to create a current overload deliberately i.e. run two two high-powered electrical appliances (such as, say, a 12 amp vacuum cleaner and a 2 kilowatt electric kettle) together on a circuit that is protected by a 15 or 20 amp circuit breaker. Or create a short circuit.
What are the devices contain in a circuit breaker?
The devices contained in a circuit breaker consist of a bi metal strip for over load protection and a small wrap of wire in the form of a coil for magnetic short circuit trip.
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.
