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.
Fuses are installed to protect the electrical installation in the event of a possible short circuit between phases and earth or between phases and the neutral conductor. Without a fuse(s) in the event of short circuit the electricity conductors (cables, wires) will get very hot to the extend to cause fire.
Short circuit energies can be very high and exceed the energy release of two sticks of dynamite in 480V systems.

What device protects an electrical circuit?
An example of a circuit protection device is a fuse. Another example is a circuit breaker.
A divice in a circuit that contains a metal strips that melts when the circuit is overheated is called a?
ummm a fuse.
If a fuse melts does it create an open circuit a closed circuit or a short circuit?
If a fuse melts, it creates an OPEN circuit, meaning that no current flows in the wires because it is no longer a complete circuit.
What has to be replaced after a short circuit?
Hopefully it's a fuse.
What will happen if a phase and neutral test by a mutimeter shows continuity?
If the test shows that there is a continuity between the phase leg and the neutral with no load connected, then that circuit should not be energized. If the circuit was energized then the fuse or breaker protecting that leg will trip the circuit open.
What will happen if a thick copper wire is used in fuse?
If a thick copper wire is used in a fuse then by definition of a fuse this device would no longer be defined as a fuse. A fuse in a circuit is used to protect the conductors feeding the load of that circuit. The circuit, if using a thick copper wire in a fuse, would then be considered as a non fused circuit.
What does a short circuit happen?
when the fuse is not working
What will happen to a safety device if there is short circiut?
If your reference to a safety device is a fuse, then if there is a short circuit, the circuit will be de energized by the opening of the fuse.
What would happen if you used a 60 amp fuse in a 6 amp circuit?
On a fault condition of the circuit, the current most likely will not be removed. If this happens components in the circuit will most likely act as a fuse and will components will be completely destroyed. This is why the manufacturer recommends what size of fuse to use in their equipment and this fuse size should always be used.
What do you think would happen if you put a 3A fuse in a plug used for kettle?
I know what would happen. The three amp fuse would blow. Any device that is plugged into a receptacle with out having sufficient resistance to limit the current flow will dead short the circuit and cause the breaker that feeds the circuit to trip. In this case the fuse being of a lower rating that the feed breaker the fuse will blow without tripping the receptacle's feed breaker.
When you will get to know that short circuit will happen?
1. That if a short circuit occurs we will get a sign before short circuit will happen or not ? 2. what we can do ? 3. how fuse can get a short circuit ? 4. which wires we have to use from preventing short circuit ?
What happen when a fuse wire of 100 ampere is used when a circuit at home draws a maximum current of 20 ampere?
If a 100 ampere fuse wire is used in a circuit where the maximum current drawn is 20 ampere, the fuse wire will not blow as the current is below the rated capacity of the fuse. The fuse wire is designed to protect the circuit by blowing and breaking the circuit when the current exceeds its rated capacity, preventing damage to the circuit components.
What could happen if a blown fuse were replaced with one that blew at a much higher current than the original?
The circuit or device that the fuse was meant to protect would not be protected if a fuse with a higher rating were to be used. This could result in the circuit or device being destroyed by a higher than normal current flow in a short circuit fault condition.
What happens when the circuit is complete and the switches are closed?
*Look at the simple circuit illustrated in Figure A-2. What will happen when only switch S1 is closed? Correct Answer= "Nothing will happen-the light bulb won't light up." <<>> If there is a load in the circuit the load will operate. If there is no load in the circuit and it is complete then a short circuit will occur and something in the circuit will burn open. If the circuit is complete and there is a fuse or breaker in the circuit, then the fuse or breaker will open the circuit.
An electrical tool that melts to open a curcuit?
fuse
What would cause 80 amp alt fuse to keep blowing?
Short in the wiring, fuse too small for the circuit, circuit overloaded, or short in something plugged into the circuit.
What happen if fuse is connected to neutral wire?
The fuse will be blown off in case of any fault. But the circuit will not be isolated because of the presence of fuse in nutral line. current will still flow and the line will be so dangerous.
