Circuit breakers are mechanical switches that detect excessive current. Then, discuss which type of electrical shutdown system you should have.Įlectrical panels are metal boxes that house circuit breakers and feature a panel cover. Let's look at the distinctions between fuse boxes and electrical panels. While they are both meant to cut power and protect your home, they are not the same. Many people mistakenly use the terms fuse box and electrical panel interchangeably. Protects against overload & short-circuits Needs comprehensive equipment (relays) for automatic operation This simple switch operation makes it straightforward to manually turn off electricity to individual circuits when working on wiring in specific regions of the home.įuses are often less expensive and can be obtained at any hardware store, however circuit breakers have additional applications that protect against more than just overheating, such as electric shock.Ĭheck out the table below for the main differences and applications based on practical variables like operating time and functionality.īased on a conducting material’s heating propertyīased on a electromechanical principle – a switching mechanism
To re-establish the flow of electricity to the residence, just flip the circuit breakers back to the ON position. Bimetallic strips are made up of two strips of two different metals high current causes the thinner of the two strips to bend, causing the switch to be thrown to the off position and the connection to be broken.Ĭircuit breakers, unlike fuses, can be reused. Unsafe quantities of electrical current in an electromagnet generate a magnetic force strong enough to turn a metal lever in the switch to OFF, terminating the current. When the switch is turned ON, electrical current can flow from a lower terminal to an upper terminal. An electromagnet or a bimetallic strip coupled to a simple switch is used in the basic household circuit breaker. This would allow excessive current to pass through, causing overheating in the cables and maybe resulting in an electrical fire.Ī circuit breaker is another type of safety device that contains an internal switch mechanism that can be tripped in the event of an electrical surge. Never replace a fuse with a higher rated fuse than the manufacturer intended for the circuit for safety reasons. Fuse ratings should always be slightly higher than the average operating current of the circuit they protect for practical reasons. Fuses are available in a variety of amperage ratings to handle varying electrical current capacity.
It must be replaced with a new fuse of the same kind and amperage rating. In the event of an electrical overload, the filament will melt, shutting off the electrical current and stopping the flow of electricity before the excess current may harm your home's wiring or create a fire hazard.Ī fuse that has been blown cannot be reused.
Under normal conditions, the fuse permits electricity to easily travel across circuits through the filament. The fuse is connected to a central fuse box, which houses the wiring for the entire home's energy. It's just a piece of metal that melts when it gets too hot.įuses are created in a variety of ways, but the most typical is using a thin wire filament wrapped in glass or ceramic and housed within a metal shell. Ⅵ Frequently Asked Questions About Fuse BoxĪ fuse is an overcurrent protection device found in the service distribution panel. Ⅴ Things to Consider When Choosing a Fuse Box It is now difficult to obtain insurance for fuse boxes. If the overloaded current continues to flow rather than being switched off, replacing fuses with bigger fuses or bits of copper can quickly grow hot and ignite a fire. Fuse boxes are likely unmaintained and contain several electrical wiring difficulties, such as cloth wiring or knob & tube, due to their antiquity.įurthermore, because fuses must be replaced every time one blows, many electricians upgraded/recommended that homeowners build electrical panels.įinally, fuses quickly earned a bad reputation among insurance companies because to homeowners replacing fuses with sticks of copper or larger-than-necessary fuses in order to stop blowing fuses.
