Because a fuse is more reliable in the case of an auto mobile but not anywhere with extricable high voltage.

How does a circuit breaker operate?
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.
When using a 30 amp fuse on a single circuit in a series will you have a problem using a 10amp and a 23.9 amp appliance at the same time?
Well, do the math. You shouldn't run a combined load of 33.9 amps off a circuit fused at 30 amps. Depending on the type of fuse (if it is a fuse and not a circuit breaker), the fuse may burn instantly or hold for a while before burning.
What size circuit breaker is needed for a 300 watt bulb?
A 15 amp circuit breaker will handle this situation very well. The smallest home breaker is rated at 15 amp.
How works oil circuit breakers?
A circuit breaker is a safety device that is put in an electrical circuit. When something fails, or shorts out, the circuit breaker "senses" the excessive current and automatically opens (or breaks) the circuit. They are used in homes, as well as some electrical devices. They are different than a fuse in that a circuit breaker can be reset. A fuse on the other hand, has to be replaced once it opens up. I hope this helps you. for more info, here is a web page about circuit breakers: <a href="http://www.wisegeek.com/what-is-a-circuit-breaker.htm">Ciruit breakers</a>
What is exactly answer of circuit breaker?
A circuit breaker is an overcurrent protection device. As well as being able to open and close a circuit supplying its rated load, a circuit breaker must also be capable of interrupting and closing onto an overcurrent, including a short-circuit fault, without damaging itself.
How is the fuel pump on a 1989 Ford Bronco XLT powered is it by a fuse or circuit breaker and where is it?
it should be powered by a fuse that can be found under the hood in a secondary fuse compartment or/and it has a fuel pump relay switch located by your airfilter. Well if your wondering where the fuel pump is it is located inside you gas tank. That's right you have to drop your tank just to change your fuel pump....FORD gotta love them.
Why do none of the windows work but there is not a fuse and circuit breaker is good what next?
I had the same problem with our 1998 Pontiac GP. Both windows suddenly failed to operate. Checked the circuit breaker, that was fine. Could not find any other type of fuse related to the windows. The answer? The electrical pigtail that should have been plugged into the two window operating switches on the drivers side door had come loose. Once reconnected, all was well. (To access the wiring, just GENTLY pry up the switch panel from the bottom - below the two window switches.)
What Type of equipment of circuit breaker?
Well from my experience , i know that the equipment used for testing is called, Electroclysis Differentiator with a Dicasidace Robinium resistor.
Where is the circuit breaker that controls the power door locks and courtesy lights in a 1993 Chevy Lumina?
if your cig light is not working as well, the fuse is in the glove box top and last in that row, had the same problom.
What does a eletrical fuse do?
a fuse is something In a circuit ...that probably wont help ...oh well!
Why will the power windows not work on a 1967 Cadillac Fleetwood?
The Fleetwood of this vintage has a circuit breaker on the fuse panel. It is a cylindrical device that snaps in like a fuse and on the bottom of the fuse panel. Check your manual for the exact location. That may --not-- be the problem, it could be a fuseable link between there and the starter, where the power divides coming from the battery. There is a possiblity of a problem with the ignition switch causing the problem as well. Also, this divine classic has the "Emergency" switch and bypass switch, which could be root of the problem. The best thing is to become friends with your DC voltmeter and trace out the circuit. A Cadillac shop manual is your best friend for doing this. I have one for my 1968 Fleetwood Limo and have spent many "quality" hours with this good book.
How are fuses and circuit the same?
Well, they are not. A fuse can be one part of a circuit. It limits the amount of power that can flow through the circuit.
