Any overload might result in a fire since there isn't a standard method of limiting current without the circuit breakers.
Circuit breakers cannot and do not protect a person from being electrocuted (a ground fault interrupter GFI breaker can, but that is a different device that is only required on outlets near water like sinks and showers). The ONLY reason they are there is to prevent a short circuit from causing the wiring to melt and catch the house on fire!!! They are thus a requirement of both the electrical code and the fire code. What is likely to happen is if that circuit was connected by a licensed electrician he would lose his license and probably be criminally prosecuted and you could also sue him for damages in civil court. If not installed by a licensed electrician when (not if) your house eventuallyburned down and the fire investigation was done, your insurance would refuse to pay any claims for fire damage as the building failed to meet code and that failure was the direct cause of the fire.

The electrical code calls for an over current device every time there is a conductor size change. On a 100 amp service, the conductor size is a #3, with an insulation factor of 90 degrees C it is rated for 115 amps. This is the same ampacity rating of the distribution panel. You can see that by installing a household circuit with a #14 conductor which is only rated at 15 amps, the only overload protection for that wire will be the 100 amp main breaker ahead of it. Drawing 100 amps on a #14 wire will heat the wire up to a point where the insulation will melt off the wire. If the wire grounds out sparks will fly and this action could ignite surrounding combustible material. To answer the question, if you are not standing physically close to the panel nothing will happen to you but you might not have a house left to live in.

Where can you find a series circuit in your house?
The breaker panel. Breakers are placed in series with all outlets.
Which circuit breaker use in house?
It depends on the manufacturer of the circuit panel. Only their breakers are acceptable for use in their panels. That being said most breakers are 10 or 15 amp load breakers for lights and outlets with 30 amp load breakers for large appliances. The breaker used depends primarily on the size wire used in the circuit as undersized wiring will cause fires.

Where is the circuit breaker in a garage?
If your circuit breakers are in the garage, they would be in a electrical panel (a metal box mounted on a (usually) outside wall, with the electric meter on the outside. The circuit breakers can be either just below the meter on the outside on opposite it inside the garage. It would usually be very close to where the electric connection to the house is. The electrical panel and breakers are not necessarily in the garage.
How do you prevent a short circuit in a house?
To avoid any short circuit in a house we suppose to have electrical panel with proper size of circuit breakers. These breakers installed to feed a number of circuits in the house which is controlled by the Electrical Code. The breaker ampacity is depend on the load size (light circuits, outlets, microwave, dryer, furnace, cenral vacuum). The individual circuits are calculated depend on the size of the load (like motors, transformers sucking a lot more power, current when they start) and this will be the base to figure out the proper wire size for feeding the circuit. When a short circuit occurs at the farthers point from the breaker this overcurrent device suppose to open up the circuit to avoid overheating ang fire.
What are switches in a circuit box called?
Generally relays or contactors If you are talking about an electric panel in your house, they are called breakers.
What does a circuit breaker do for the safety of a house?
A circuit breaker sets a limit on the amount of amperage that can be applied to the circuit's conductor. This is why wires and breakers have amperage ratings. The wires ampacity is matched to the breakers ampacity. If there is a higher that normal amperage capacity, than what the wire is rated for, the breaker will trip the circuit open.
Which circuit breaker to use for the plugs and geysers?
The size of circuit breaker you use for the plugs and geysers depends on the size of the house. Circuit breakers play an important role in homes in keeping electricity supplied.
How are circuit breakers rated?
Circuit breakers, like fusible links (fuses), are rated according to the maximum amount of current (load) they can support before the circuit is interrupted. Many appliances have their own circuit breakers, typically rated at something less than 10 amps. In general, breakers are designed to open (turn off the circuit) when the current has been slightly exceeded for more than a few seconds, or greatly exceeded for less than a second. If you're attached to the circuit, you'd be electrocuted before the breaker blew, but at least the house wouldn't burn down. Home circuit breakers come in many sizes and configurations, ranging from 15 amps to 400 amps (for main disconnect), with intermediate sizes including 20, 30, 40, 50, 60, 70, 100, 150 and 200 amps, among others. Breakers are also classed by how many poles they have, whether both poles open simultaneously, what additional safety features there are (GFCI, arc-fault), who makes them, and what model panelboard they are to be installed into.
What simple device is installed in house wirings to prevent damage due to short circuit?
Fuse or circut breaker
Advantages and disadvantages of circuit breakers?
no disadvantages. advantages: keep from being electrocuted, keep wires from melting and burning your house down, protecting appliances from destruction, etcCommentCircuit breakers are designed to protect cables and appliances, NOT people! To protect people against electrocution, you need a residual current device (ground-fault interrupter).
What is the biggest circuit breaker in a house?
The biggest circuit breaker in any home is the main breaker located in your main breaker panel that is installed where your electrical service cable comes into your home.
What is circuit breaker and its type?
A circuit breaker(s) is what you will find inside your electrical box in your house the idea behind them is when a room in your house draws too many Amps the circuit breaker will turn off all the power to that room to re-engage them you simply switch it back on. There are many types of circuit breakers with different rattings like 15A or 100A, this tells you at what point they will 'break' the circuit and turn off the power.
What can happen if your house was struck by lightning?
They usually have grounding cables that redirect the lightning from the house straight to the ground without going through any appliances. It could trip the breakers though.

How is electricity supplied around a house?
Electricity is supplied around the house through a service distribution panel. From this panel specific circuit are wired to supply power to plugs, lights and appliances. Each circuit is protected by a breaker that is located in the distribution panel. These breakers vary in trip values to accommodate the load wattage's of different appliances that are connected to the circuit.
What is the purpose of a circuit breaker?
circuit breakers are designed to cut off power to an electrical circuit when too much amperage is drawn through the wires. different size wires are used to carry more or less amperage. for instance, 14 guage wires are usually set with 15 amp breakers. and 12 guage wires are usually set with 20 amp breakers. pulling too much power through too small of wire will cause the electricity that is supposed to be going to your appliance to turn to heat energy in the wires and is the #1 cause of electrical related house fires. breakers protect you in the event you are drawing too much power through a single circuit.
A 120 v general purpose circuit should have circuit breakers or fuses with values of?
The fuses and/or breakers in a home should be matched to the circuits. A qualified electrician can help you make the proper calculations. Do not attempt repairs or modifications if you do not have adequate knowledge about electricity or proper electrical construction practices. Mistakes can be fatal or at best, expensive. You can burn down your house or electrocute yourself or others.
