15 amp type s fuse

Most of the circuit breakers in your panel are probably rated for 20 amps and can handle appliances as well as light circuits. You may have one or more circuits dedicated to lights, however, with each being controlled by a amp breaker.

The minimum wire size for those amp circuits is gauge. Resistance in electrical conductors produces heat when electricity is flowing, and the amount of heat varies inversely with the cross-sectional area of the conductor. A amp breaker, on the other hand, will trip before gauge wire overheats.

Because it has even less chance of overheating, gauge wire is also acceptable on a amp circuit. Because it's thinner and lighter, gauge wire is easier to run than gauge wire. However, gauge wire is acceptable on both and amp circuits, so some electricians use it exclusively when wiring a house. This avoids the potential for mixing wire gauges in future repairs or additions, which is prohibited by the National Electric Code because it's a fire hazard.

By Chris Deziel Updated December 27, About the Author.He was the person who suggested the utilization of reduced part of conductors to guard telegraph stations against the hits of lighting with liquefying, the slighter wires would guard equipment along with wiring in the building.

In the yearlighting installations and telegraph cables can be protected by employing a variety of foil fusible essentials and wires. At the end, Thomas Alva Edison earned rights for a fuse which is an element of his electric distribution system in the year And now, this article discusses fusetypes of fuses, and its applications in various fields.

What is Fuse : Different Types and Its Applications

In the field of electronics or electrical, a fuse is considered as the most crucial device which is employed in various electrical circuits that give protection from the overcurrent conditions. The device is included with a metal strip where it gets dissolved when there is a flow of an extended range of current values. Because of the metal dissolving, the circuit becomes an open circuit and disconnects the flow of power supply through the device.

It is also termed as an automatic disconnection of supply that is frequently shortened to ADS. This is the cheaply available device that is implemented for protecting the electrical circuits in the conditions of either circuit short or high range of current magnitudes.

These are used to prevent the home appliances from the high current or overload damage. When the fuse gets break or damage, then an abrupt sparkle happens which may direct damage your home appliances. That is the major reason we require different types of fuses to guard our home-appliances against damage. There are many types of fuses used for circuit protection. Fuses are generally rated in Amperes. Even though their functionality is based on the self-production of the heat in the scenarios of additional current through their own developed electrical resistance.

This can be generally achieved by making the fuse wire length to be as short as possible. As the wire length is not dependent on current rating values, the minimal length of wire imposes the minimal value of resistance. There are few characteristics for the fuses in the electric domain and those are explained as below:.

It is fabricated with a lean strip or thread of metallic wire. The connection of the Fuse in an electrical circuit is always in series. When there is the production of a high level of current electrical circuits, the fuse gets soften and it makes the circuit be in an open condition. The extreme flow of current may direct to the collapse of the wire and prevents the supply. The working scenario of this device is mainly dependent on the heating condition of the current.

In the general functioning of the current, there will be a normal flow of the current through the fuse.

Because of the current flow, heat will be developed in the fuse element and the generated heat will be dissipated into the atmosphere. Due to this, the temperature level of the heat is maintained less than the melting point values.Here at Walmart. Your email address will never be sold or distributed to a third party for any reason.

Types of Fuses

Whenever a sudden short or surge threatens any of the delicate electronics found in modern cars and trucks, a fuse stands ready to valiantly throw itself into the field of fire.

In doing so, the fuse takes a figurative bullet for some more valuable, complex, or indispensable component or device, like a car stereo or amplifier. This often results in some temporary loss of functionality, but fuses are cheap and usually easy to replace, and any underlying problem will typically be revealed by repeated failures of a fuse on the same circuit.

Fusible links, while different in design, are identical in purpose and functionality. There are many different types of fuses, but most modern cars and trucks use one or more of the following types of bladed fuses, in descending order of size:.

There are multiple sizes and configurations of blade fuses today, but they all bear a physical resemblance to the original ATO fuses, and many applications still use standard ATO and ATC fuses.

The differences between these various types of blade fuses are primarily size and number of terminals, although physically larger fuses are usually used in higher current applications. Glass tube fuses consist of a glass tube, capped by metal terminals, and with a metal strip passing through the center. Bosch type fuses are also roughly cylindrical, but they are made of a solid ceramic material with a metal strip on the surface.

Since automotive fuses are differentiated both by design type and current rating, all fuses most emphatically are not the same. Although it is definitely possible to replace any ATO fuse with any other ATO fuse, doing so can be extremely dangerous if the wrong amperage fuse is substituted.

Similarly, it is sometimes physically possible to replace a Bosch type fuse with an American-style glass tube type, but sticking to the same amperage rating is imperative, and a flat-capped glass tube fuse will typically not fit well into a fuse holder designed for conical end caps.

There are six types of blade fuses that you may run into when you pop open the fuse box on a modern car or truck: micro2, micro3, low-profile mini, mini, regular and maxi. For all blade fuses, the housing may be opaque or clear. When the housing is clear, it's usually easy to tell whether the fuse is bad, since the winding metal strip that connects the two terminals is easily visible.

If the strip is broken, that means the fuse has blown. Micro2 fuses are the smallest type of blade fuse, and they are easily identifiable by the fact that they are so much taller than they are wide. In terms of size, low-profile mini fuses and regular mini fuses share the same body height and width, but the spade terminals of low-profile mini fuses barely extend past the bottom of the body.

Micro3 fuses are larger than Micro2, low-profile, or mini fuses, but they are most easily identifiable by the fact that they utilize three spade terminals. Every other type of blade fuse only uses two terminals. They also include two fuse elementswhich allows a single fuse to effectively handle two circuits.

Although many applications started to replace ATO and ATC fuses with mini fuses in the s, they are still widespread.

These fuses are wider than they are tall, and they come in two main types. The largest type of blade-style fuse is the maxi fuse. These are significantly larger than any other type of blade or spade automotive fuse, and they are typically used for higher current applications. Although fuses can blow under normal operating conditions, due to age and wear, a blown fuse often indicates a deeper problem.

So if you replace a blown fuse with another fuse with a higher amperage rating, you may prevent the fuse from blowing again immediately, but you also risk damaging some other electrical component, or even starting a fire. There are three different ways to tell the amperage of a blade-type fuse. The first is to look at the top of the fuse, where you will find the amperage rating printed on or stamped into the plastic.Bussmann series plug fuses are used in residential applications to protect furnace blower motors, pumps, power tools, garage door openers, and more.

Its essential component is a metal wire or strip that melts when too much current flows through it, thereby stopping or interrupting the current. It is a sacrificial device ; once a fuse has operated it is an open circuit, it must be replaced or rewired, depending on type. Fuses have been used as essential safety devices from the early days of electrical engineering. Today there are thousands of different fuse designs which have specific current and voltage ratings, breaking capacity and response times, depending on the application.

The time and current operating characteristics of fuses are chosen to provide adequate protection without needless interruption. Wiring regulations usually define a maximum fuse current rating for particular circuits. Short circuitsoverloading, mismatched loads, or device failure are the prime or some of the reasons for fuse operation. A fuse is an automatic means of removing power from a faulty system; often abbreviated to ADS Automatic Disconnection of Supply.

Circuit breakers can be used as an alternative to fuses, but have significantly different characteristics. Breguet recommended the use of reduced-section conductors to protect telegraph stations from lightning strikes ; by melting, the smaller wires would protect apparatus and wiring inside the building.

A fuse was patented by Thomas Edison in as part of his electric distribution system. A fuse consists of a metal strip or wire fuse element, of small cross-section compared to the circuit conductors, mounted between a pair of electrical terminals, and usually enclosed by a non-combustible housing.

The fuse is arranged in series to carry all the current passing through the protected circuit. The resistance of the element generates heat due to the current flow.

The size and construction of the element is empirically determined so that the heat produced for a normal current does not cause the element to attain a high temperature. If too high a current flows, the element rises to a higher temperature and either directly melts, or else melts a soldered joint within the fuse, opening the circuit.

The fuse element is made of zinc, copper, silver, aluminum, [ citation needed ] or alloys [ clarification needed ] to provide stable and predictable characteristics. The element must not be damaged by minor harmless surges of current, and must not oxidize or change its behavior after possibly years of service.

The fuse elements may be shaped to increase heating effect. In large fuses, current may be divided between multiple strips of metal. A dual-element fuse may contain a metal strip that melts instantly on a short circuit, and also contain a low-melting solder joint that responds to long-term overload of low values compared to a short circuit. Fuse elements may be supported by steel or nichrome wires, so that no strain is placed on the element, but a spring may be included to increase the speed of parting of the element fragments.

The fuse element may be surrounded by air, or by materials intended to speed the quenching of the arc. Silica sand or non-conducting liquids may be used. The speed at which a fuse blows depends on how much current flows through it and the material of which the fuse is made.

The operating time is not a fixed interval, but decreases as the current increases. Fuses have different characteristics of operating time compared to current. A standard fuse may require twice its rated current to open in one second, a fast-blow fuse may require twice its rated current to blow in 0.

Fuse selection depends on the load's characteristics. Semiconductor devices may use a fast or ultrafast fuse as semiconductor devices heat rapidly when excess current flows.

The fastest blowing fuses are designed for the most sensitive electrical equipment, where even a short exposure to an overload current could be very damaging. Normal fast-blow fuses are the most general purpose fuses.
