In a Square D breaker panel, the two hot legs are fed through the center buss bar and breakers snap to the panel getting their power from the bars that run through the center, and the WHITE wire is connected to a neutral strap that has multiple connections for the neutral wires of each circuit.
When connecting a circuit to the breakers, the BLACK or RED wires are connected to the breakers and the WHITE wires are connected to the neutral strap.
I seriously recommend that you work with a qualified electrician to help with any new electrical work or electrical modifications. There are far too many ways that you can introduce serious hazards to your home if you make a mistake in the wiring. Even if you hire a retired electrician to help you, he could give you the pointers that will make your wiring project more safe for you, your family and your property.
Do NOT attempt any wiring project if you do not have a good understanding of this and other, similar issues.
A circuit breaker can be magnetic; the higher the current is the stronger the magnetic field will be, if the magnetic field gets strong enough it will pull open the circuit. A circuit breaker can also be thermal; as current travels through the circuit heat is generated (higher current = more heat), in the breaker there is two different kinds of metal bonded together, each will expand and contract at different rates, since they are bonded together they will bend and trip the circuit open. A circuit breaker can be a combination of magnetic and thermal.
If everything is working as it should then no current flows when the breaker is off. This is no better example of this than there is on answers. When a do it yourselfer looks for an answer and gets one, the answer is always ended with the suggestion that before doing any work always shut off the breaker. If the breaker is malfunctioning one symptom is that a voltage is still present even though the handle is in the off position. If this is the case change the breaker out immediately.
Not unless the leakage current gets higher that what the trip setting of the breaker is. In many underground conduit systems the feeder conductors are in water continuously due to leaks in the under ground conduit system.
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
A circuit breaker is a overcurrent device. It prevents fire.An electrical circuit is only as strong as its weakest link. When the voltage rating of a device is exceeded, it arcs. Current overloads are less obvious and easier to create. When the current rating of a device is overloaded, the device gets hot, eventually burning up. This can cause a fire.You want your breaker to be your weakest link, because it is designed to safely handle overcurrent situations. If your breaker is not the weakest link, wiring or a wiring device in your home will fail first, possibly setting your home on fire.Some things to remember:A breaker is a safety device. It is there to protect conductors and equipment.Only a Ground Fault Circuit Interrupter (GFCI) breaker will protect people from a shock or electrocution.If it pops, something is wrong. Chances are it is not the breaker! It is against the NEC to reset a breaker unless you know it was an overload condition. If it is a short-circuit, it must be fixed before resetting.Do not replace a breaker with a larger one. The circuit it is feeding cannot handle the extra current and will burn up before the new breaker trips.If a breaker trips frequently, chances are it is overloaded. Look into splitting the circuit it powers into multiple circuits on multiple breakers.If in doubt, call an electrician. Negligence is fatal with electricity.
In the electrical trade, this device is known as a circuit breaker.

That's a good description of a fuse or circuit breaker.
i had the same problem on my 89 ford van and it turned out to be (after weeks of testing parts) the circuit breaker located on the passenger fender-near the selenoid small electrical part with two threaded pieces extended from the square little box and wires connected to it-if the circuit breaker is going bad-when it gets hot-it will shut down the engine-when it is cool-youll be able to start it again check your circuit breakers & alternator

A fuse is a device that contain a thin strip of metal that will melt if there is too much current through it.A circuit breaker is a reusable safety switch that breaks the circuit when the current gets too high.They are used to prevent circuits from overheating.
Not unless the leakage current gets higher that what the trip setting of the breaker is. In many underground conduit systems the feeder conductors are in water continuously due to leaks in the under ground conduit system.
Check the wattage or amperage of your kettle. It sounds like you are overloading the circuit. Most circuits will be on a 15 amp breaker. If the circuit has more that one receptacle on it there may be other appliances drawing amps off of the same breaker. To test this theory try the kettle in other parts of the house and see if it trips a different breaker.

An electrical contractor or electrician would definitely be competent to help with that repair. The handyman laws in some states allow a handyman to perform minor repairs such as replacing a circuit breaker. It's a simple process, you just have to make certain that you shut down the power so nobody gets electrocuted. Replacing a circuit breaker is not a minor repair, NFPA 70E - Standard for Electrical Safety in the Workplace as well as the National Electrical Code state that only a qualified person can do electrical work. A qualified person is "One who has skills and knowledge related to the construction and operation of the electrical equipment and installations and has received safety training to recognize and avoid the hazards involved."
