A circuit breaker is supposed to protect the more valuable component the circuit is connected to. Too low a resistance, a minor glitch (spike) will break the circuit and stop the device from working. Too high a resistance, no glitches, no matter how large (a child sticking a paper clip into the wall sockets, for example), will break the circuit and the device (child) may get damaged. Each circuit will have a purpose (power load), and the circuit breaker should be chosen for that purpose with some tolerance. A free standing closed circuit breaker should have no resistance across its internal contacts. The main purpose of a circuit breaker is to protect the conductors that supply the load. If the current going to the load becomes greater that the amperage rating of the wire the circuit will open thereby saving the conductors from damage. Once the load current is below the wire rating ampacity, the breaker can be reset for normal operation.

Which is better glass or polycarbonate?
Whether glass or polycarbonate is better depends on the application, as each has its strengths and weaknesses: ✅ Glass – Best for Clarity & Scratch Resistance Pros: Excellent optical clarity (crystal clear) Highly scratch-resistant UV stable (won’t yellow over time) More rigid and aesthetically refined Cons: Brittle – can shatter or crack on impact Heavier than polycarbonate Best for: Windows, aquariums, high-end displays, and places where clarity and scratch resistance matter most. ✅ Polycarbonate – Best for Impact Resistance & Flexibility Pros: Extremely impact-resistant (250x stronger than glass) Lightweight Shatterproof Easy to cut and shape Cons: Prone to scratching unless coated Can yellow over time if not UV protected Best for: Safety glazing, eyewear lenses, riot shields, greenhouse panels, and areas where durability and safety are key.
Is gear cycle better or normal?
gear cycles are better than normal cycles because gear cycles are comfotable for riding as compared to normal cycles
Is stranded copper wire a better conductor than solid copper wire?
no
Which of these describes a benefit of tissue engineering as compared to traditional prosthetic technology?
Better biocompatibility
Explian about cryogenic hardening?
Cryogenic hardening is often referred to cryogenic treatment and cryogenic processing. Using the term "hardening" is not correct. Cryogenic treatment does not increase the hardness of metals (I.E. rockwell hardness). Rather it changes metals on the molecular level so that they perform better. Cryogenic treatment is used for a variety of reasons including improving dimensional stability, stress relieving, increasing wear resistance, and eliminating walk and creep. A typical cryogenic treatment lasts for several days. Metal and steel parts will be put in a cryogenic processor at room temperature. The temperature will slowly be taken down to -300F below. Then it will hold there for 12 to 24 hours depending on the company doing the treatment. After that, the processor will have the temperature raised back to room temperature very slowly. Finally, the parts will be post-tempered to finalize the cryogenic treatment. Cryogenic treatment re-aligns the micro-structure of the metal to improve its structural stability. Retained austenite will be converted to martensite which allows for a tougher piece of metal. The eta-carbides in the metal will become precipitated which allows for a much higher degree of wear resistance. Below are some good sites for additional reference...
What is Ir value of a circuit breaker?
Ir is the Interrupt rating of the circuit breaker. It is the maximum amount of current the breaker can withstand without damage. In a molded case breaker's electronic trip mechanism, Ir is the continuous current rating that you select, to trip the breaker at a given overload current. Standard requirements request that the breaker trips at 2 hours with an overload of 135% and will trip as a function of I squared x time selected for higher currents.
What are the advantage of an oil breaker transformer?
I'm not aware of any device called an 'oil breaker transformer'.However, an oil circuit breaker or, more correctly, an 'oil-filled circuit breaker' is one of several types of circuit breaker used in high-voltage systems. The oil has two functions: (1) it is a far better insulator than air, enabling the circuit breaker to be far more compact (reducing its 'footprint'), and (2) the oil is used to extinguish the arc when the circuit breaker trips under fault conditions -a jet of oil removes ionised contaminants from the arc path, lengthens and 'snaps' the arc, and cools the arc.
How does a solid state circuit breaker works?
Recently a new technology "solid state' are applied to traditional circuit breaker. This technology has resulted in freeing circuit breaker from arcing and switch bounce, also offering higher reliability and longer lifetimes and a faster switching time.
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.
Does the current still flow when the circuit has blown?
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.
What one is better fuse or circuit breaker?
IMO it would be because the circuit breaker has the possibility of going bad and not working (allowing a short to move through the device), but fuses blow (cause a break) no matter what if shorted.
What are the benefits of upgrading to a new circuit breaker for your home's electrical system?
Upgrading to a new circuit breaker for your home's electrical system can provide increased safety, improved protection against electrical fires, better reliability, and the ability to handle higher electrical loads.
Are circuit breakers more expensive the better they are?
On one hand you don't want to search for the absolute cheapest circuit breaker you can find.On the other this is a competitive business and most circuit breakers have similar quality and price ranges
What if your circuit breaker started tripping with no change of things plugged into an outlet Does this mean the circuit breaker needs to be replaced?
Circuit breakers can degrade over time but it would be better to get a competant electrician to do it. It might also mean you have too many things plugged into one outlet. Sometimes one circuit breaker may protect several outlets so it might be tripping because of a change in another outlet. ELECTRICTY IS DANGEROUS!!!! Don't do it yourself.
What are the benefits of a circuit breaker upgrade for a residential electrical system?
Upgrading a circuit breaker in a residential electrical system can enhance safety by reducing the risk of electrical fires and overloads. It can also improve the efficiency and reliability of the electrical system, providing better protection for appliances and electronics.
My circuit breaker keeps popping I have replace the 2-prong outlet with a 4-outlets and why is it still popping?
A breaker trips when there is too much current. If you unplug everything on the circuit and the breaker still trips then you have a wiring problem or a bad breaker. From your description it is not possible to be certain if the problem started when you installed new outlet or previously. You have to describe your problem in better detail to get a good answer. When you have a circuit that trips the corresponding breaker, you need to go through each outlet on the circuit and rule it out as the problem. This can be done by pulling each outlet, from the wall and systematically remove wires from outlets while power is off and determining when problem goes away.
What are the benefits of upgrading to a new circuit breaker with enhanced features and capabilities?
Upgrading to a new circuit breaker with enhanced features and capabilities can provide increased safety, better protection for electrical devices, improved efficiency, and easier maintenance. These advanced circuit breakers can also offer enhanced monitoring and control options, helping to prevent electrical issues and reduce downtime.
