Multi-read content when were circuit breakers first used in homes

Man Studying Plans - Retro Clipart IllustrationCircuit breakers are arguably one of the most useful innovations in wiring. Its main function is to protect the electrical circuit from damage in the event of a short circuit or current overload. It is unique in that you can reset the circuit breaker to make it work again. In the past, the use of a fuse was the norm. The problem with the fuse is that it will need to be replaced each time a short circuit occurs.

The first circuit breaker was designed by Thomas Edison in 1879, when he had the idea to protect electrical wiring used for lighting from common overload and short circuit problems. Of course, we now know that his system suffered from a fatal misuse of fuses that had to be constantly replaced.

Many other inventors up to the 1940s would present their version of circuit breakers and progress was made. Looking at their designs, it’s fascinating to see how many of them are representative of those commonly used today. It wasn’t until the 1940s that circuit breakers became popular in homes, factories, and buildings.

Our need for circuit breakers

In the 21st century,Circuit breakers are used almost everywhere. Houses, buildings and entire towns can supply electricity to its inhabitants. People no longer have to worry about losing energy from a single short circuit, and they are designed to withstand high voltages and currents. With the world’s population increasing and the demand for electricity increasing, there is no choice but to design circuit breakers that allow it. But how did we get to the point where circuit breakers became so reliable and powerful?

Circuit breakers are used in

To answer this question, we must go back to the 1940s. Back then, circuit breakers were still a rare commodity when it came to the management and use of electricity. Many people are still experimenting with different ways to make circuit breakers as efficient as possible while allowing them to handle higher current levels. In a family home setting, the standard is a 30 amp fuse panel providing 120 volts. Two plug-in fuses have been installed to protect the branch circuits and you have a large switch to turn off the power.

By the late 1950s, 60 amp circuit breakers were the norm, and they could supply twice as much voltage as earlier models. This is because you now have four socket fuse blocks and two cartridge fuse blocks. As a result, there are now four separate branch circuits. This is the first time you can label where each branch circuit is fed.

Electrical ground wires connected to a metal plate junction.

By today’s standards, the power these panels can provide is very limited. Your normal standard of living would cause relentless overloads and shorts in a 50s house, even with the best circuit breakers they could use!

Things improved in the 1960s when circuit breakers took on the form of a single panel offering multiple ranges of circuit breakers. You can service up to 200 amps while having expandable circuit space (12 to 24 of them). What does it mean? This means that these houses can supply light to certain parts of the house and supply electricity to sockets. This is also the length of time fused circuit breakers are shipped due to the fact that they must be changed each time a fuse blows.

You won’t be able to install anything less than a 100 amp panel in today’s world. That’s how we’ve come this far in providing people with circuit breakers capable of delivering high levels of daily electrical power.

Technology used

Woman electric wiring technician at Douglas Aircraft Company, Long Beach, California. During World War 2, Oct. 1942.Now that we understand how powerful circuit breakers are, another question raised during the development of circuit breakers is the technology that has been used to improve them. After World War II, heavy reconstruction efforts were made to restore order. One area of ​​particular interest is the design of circuit breakers capable of effectively interrupting high currents.

The main challenge people face is that when you turn off the power, the air temperature near the circuit breaker immediately rises and an electric arc is formed. This arc acquires a thermal energy proportional to the amplitude of the interrupted current. According to the measurement data,”Electric arcs have enormous energy: their temperatures can exceed 50,000 C and pressures of up to 100 MPa can be contained in a volume of less than one litre.”Imagine the effect of this arc in a power station!

Circuit breakers made before the 1940s were mostly oil-filled and could only handle low voltages and currents. Oil is used because it has been shown to be a good insulator. The main weakness of these circuit breakers is that a large amount of oil is needed to quench the arc and contain it. This makes it largely impractical from a size standpoint. Also, if the arc cannot be extinguished and the pressure can build up, you will face a serious fire hazard.

electrical shield, old switchboardWith this in mind, there has been a move towards the development of air circuit breakers. The arc suppression mechanism works as follows: The pressure difference between the ambient air outside and inside the circuit breaker creates convection which cools the arc. After some tweaks and fixes, engineers were able to come up with a valve design that could safely and efficiently release compressed air from the chamber.

This gives air circuit breakers the advantage of being easier to maintain, but air circuit breakers are far from perfect – being air-dependent they are much larger than the oil circuit of circuit breakers and require more complex machinery.

For nearly 3 decades, there has been constant competition between companies that manufacture air circuit breakers and companies that manufacture oil circuit breakers. It’s hard to know which of them will emerge victorious in this technological race.

Circuit Divider

What technology is Victor?

The irony is that both types of circuit breakers will eventually be phased out in favor of superior technology:Sulfur Hexafluoride (SF6) Circuit Breakers, an inert gas that has superior insulating properties to either of the available solutions. SF6 technology was phased out in the 1960s and would eventually replace earlier circuit breakers (oil and pneumatic) in the early 1990s.

a 3d render of a sulfur hexafluoride

The SF6 circuit breaker works as follows: when an arc forms in the circuit breaker, a stream of high pressure cold SF6 gas is released and interacts with the arc to extinguish it. Sounds simple, right?

It certainly is – it outperforms other breaker designs on every front. Minimum noise level, no fear of explosion thanks to the highly flammable liquid of the circuit breaker, easy maintenance and clean operation. Predictably, this led to the sale of oil and air shut-off devices and eventually their phasing out as a thing of the past. Undoubtedly, the SF6 circuit breaker was developed to have a much larger circuit breaker capacity than any previous design.

Circuit Divider

A new tool all the way

Alongside SF6 technology, there is another viable competing technology: the vacuum circuit breaker. This circuit breaker works on the principle of extinguishing the arc in a “vacuum circuit breaker”, a sealed chamber inside the circuit breaker. When the contacts separate, a metal vapor arc is initiated and the arc is extinguished in a flash. This is possible due to the high dielectric strength that exists between the separated contacts. As a reminder, this dielectric strength is up to four times greater than SF6 gas!

One of the main advantages of vacuum circuit breakers is that they require less operating energy than SF6 circuit breakers. No additional extinguishing media are required, and it has a much greater capacity than it could possibly overload the circuit before needing to perform any form of refurbishment.

Confrontation

Currently, we have two advanced technologies that are in direct competition. Even with the benefits listed in the previous paragraph, they have reached the point where many experts agree that neither is better than the other. Some companies will prefer to use one type of circuit breaker over another for reasons such as personal preferences, company traditions and rules, etc.

Where will this leave the future of circuit breakers? Will we see a combination of vacuum technology and SF6 circuit breakers? Will a new third arise and leave them both in the dust? What can we expect?

Time to upgrade? Not completely

Two male arms reaching for each other, with a smoking electric current connecting their fingers in empty space background conceptThe biggest game-changer in this area is the ability to prevent arcing from happening in the first place, rather than having to deal with it. It forces us to rethink basic electrical principles and our understanding of how circuits are designed in the first place.

However, we may eventually see the rise of fully electronically designed circuit breakers. They won’t have to rely on gas or external materials to do their job. We have seen prototypes of this type of circuit breaker in high voltage direct current (HVDC) systems.

The only problem we have right now is substandard technology. It would cost too much and the design would be much more complicated than what we currently have with the vacuum and the SF6 breaker. You will have to wait a few decades before this type of technology becomes widely available.

Whatever technology you choose to use for your business or building, always be sure to choosea reliable, qualified and trustworthy supplierhas a large inventory and experts can help answer any questions or queries you may have. You need to choose the circuit breaker that best suits your requirements and needs.

Popular questions about when were circuit breakers first used in homes

when were circuit breakers first used in homes?

Although circuit breakers for residential panels were available in the 1930s, the earliest examples we have seen date from the 1940s. The one shown above is a Westinghouse from a house built in 1947.

When did we switch from fuses to breakers?

NOTE: Beginning in the 1960s, fuse boxes were phased out in favor of electrical systems controlled by circuit breakers. It’s important to replace an old fuse box with a circuit breaker system as soon as possible—not just for code compliance, but also for safety and convenience.

When did electrical breakers come out?

The very first circuit breaker was devised in 1879 by Thomas Edison, when he came up with the idea of protecting circuit wiring used for lighting from the common problems of current overloads and short circuits.

Why did breakers replace fuses?

Circuit breakers provide better protection for three-phase applications. Because circuit breakers are NOT sacrificial, do not require replacement, as a fuse does, power can be more quickly restored without the need to hunt down a spare fuse.

Where is the breaker box in an old house?

But today, a service panel is often called a “breaker box,” because it’s full of circuit breakers, which are far superior to fuses in terms of safety and convenience. The main service panel is typically located in the basement, or (in a house without a basement) in a utility room.

Do old houses have circuit breakers?

Many older homes were originally constructed with a fuse box instead of a circuit breaker which means that for some modern homeowners, home fuse boxes are mysterious and unusual. Fuse boxes also have a reputation for being “unsafe,” as there’s a potential fire hazard whenever they aren’t handled correctly.

What year did 200 amp service become standard?

’80’s
In the ’60s and ’70s, 100-amp service became more common – better than earlier service, but still low by modern standards. In the ’80’s, 200-amp became more common to accommodate the growing electrical demand of the various equipment in the home.

What type of wiring was used in 1960?

aluminum wire
In North American residential construction, aluminum wire was used for wiring entire houses for a short time from the 1960s to the mid-1970s during a period of high copper prices. Electrical devices (outlets, switches, lighting, fans, etc.)

How old are circuit breakers?

The Consumer Product Safety Commission outlines that the average circuit breaker lifespan is around 30 – 40 years. On the other hand, some experts instead estimate the lifespan of circuit breakers to be around 15 – 20 years instead.

What type of circuit breaker is used in houses?

Single-pole circuit breakers are the type most often found in homes today. They’re named single-pole because they’re designed to monitor the current of a single wire and trip in the event of a short or electrical overload.

Can you replace old house fuses with circuit breakers?

With the current electrical trends, electrician experts consider fuse boxes quite outdated. So, most of them recommend replacing a fuse box with a circuit breaker.

Are screw-in fuses legal?

But the National Electrical Code (NEC) has safety standards for old screw-in type (Edison) fuse panels that are still in use. Their requirements are for shock protection when changing fuses, and to eliminate the possibility of installing a fuse with a higher amperage rating than the wiring will safely conduct.

Are plug fuses still used?

Type-SL and Type-TL Fuses

SL and TL fuses are medium-duty time-delay fuses and are now the most commonly used plug fuses found in home electrical systems.

Can a house have two breaker boxes?

Overwiring is a sort of trick to get more mileage out of the main breaker panel. The panel might look normal at first glance, but it contains tandem breakers that allow two circuits to use one slot. Tandem breakers are different from double-pole breakers, which use two slots in the panel.

Do all houses have circuit breakers?

While every home is different, circuit breakers are generally located in low-traffic areas of the home, such as a basement, garage, or utility closet. If you live in an apartment, your circuit breaker may be in a more central location, such as a hallway or laundry area.

How Fuses and Circuit Breakers Work | Ask This Old House

Note that in this video the panel is new and has no external circuits connected yet. When wired in and active there is a lot of exposed live metalwork that poses a shock risk. Changing a consumer unit is not a simple DIY task due to the presence of a high current supply that poses a shock and burn hazard if touched or bridged.

In the UK we have a really simple electrical system. Just a three phase system with 240V between each phase and neutral and 415V between any two phases. (230V/400V under European tolerance standards.)

A typical home will get a single phase and neutral with the three phases spread amongst homes in a street, while a factory or commercial premises will usually get all three phases.

The higher voltage means lower current and the single phase means that our consumer units (home electrical distribution boards) are very compact and simple inside.

Traditionally they contained an isolator with a busbar that went along a horizontal row of breakers, but these days the breakers are often grouped in sections, each protected by its own main RCD/GFI. This allows the RCD/GFI to protect all the wiring in the circuit and also ensures that if a leakage fault does cause an RCD/GFI to trip, it only turns off a small number of circuits in the house. In some instances every single circuit may have its own RCBO (Residual Current Breaker with Over-current) which protects each circuit against overcurrent and fault leakage.

The use of a DIN rail for mounting the breakers means that the panel can accommodate other modules if desired. Commonly things like time switches and power supplies. Alternatively a consumer unit can be used purely as a handy housing for a row of DIN modules with the added advantage of integral power busbars.

A typical British home gets a 60A utility fuse these days, although for larger homes or applications like vehicle charging that can be upgraded to a higher value if the incoming cable is suitably rated.

Typical circuits in a consumer unit are:-

Lighting. A radial circuit protected by a 6A circuit breaker. Usually wired with 1mm or 1.5mm CSA cable. The circuit usually bounces from room to room passing through a ceiling rose connector that makes it a very versatile system for lighting.

Radial power. Often a 16A breaker feeding a special application like a heating boiler control system or immersion heater. Usually wired in 2.5mm CSA cable.

Radial circuits are also used for high current loads like cookers and showers with suitable cables and breakers.

Ring power circuit. An unusual approach to running lots of high current sockets with a loop of cable that starts and finishes at a 32A breaker. Usually wired with 2.5mm CSA cable. People make entire careers out of inventing new and pointless ways to test ring circuits. Sometimes called a ring main as the first circuits were based on power distribution ring mains that are used in the electrical utility industry. Now called ring final circuits, a new name invented by the department of paperwork.

What is a CB?

Circuit breakers are safety devices that stop the flow of electricity when it’s specifically rated parameters are passed. These can come in a few forms, the first is an Overcurrent Protection Device or OCPD, which you can read all about in Article 240 of the NEC. These circuit breakers do exactly what they say they do, use various methods to prevent a branch circuit from receiving too much current or amperage. Another is fuses. Fuses usually come in the form a tube with a metal filament inside that breaks when too much current travels through it, opening the circuit. Unlike breakers, fuses no longer function after the first short and must be replaced.

How does it work?

Thermomagnetic circuit breakers work with two elements, these are the most common breakers and the type we use most in homes and small businesses. The first element is a bi-metal strip. When too much current passes through this bi-metal strip, it heats up causing the strip to warp and change shape, releasing the spring inside of the breaker, opening the circuit to stop the flow of electricity. This slow build up of heat is caused by an Overload, which happens when the circuit is demanding more current than the breaker is rated for. The amount of time it takes for this breaker to trip is directly related to how much amperage it receives. This mechanism is what classifies this as an Inverse-time breaker. The more amperage they receive the quicker they trip, but if the overload is minimal, say two or three amps, it will take much more time to trip than if the breaker experienced a short. Google an inverse breaker time table and get a good look, it’s pretty cool stuff.

The second element of thermomagnetic breakers is the magnetic! When a short occurs in a circuit, an intense amount of electricity is released in the form of light and heat. This huge flow of electricity creates a magnetic field that instantaneously separates the magnetic strips inside the breaker, causing it to release the internal spring that trips the lever and opens the circuit. This type of tripping classifies these breakers as Instantaneous. Because of how many amps these short circuits can generate, most standard residential circuit breakers are rated to withstand 10,000 amps before completely blowing up and melting.

Some breakers come with extra components that allow for more versatile control, like the Shunt-Trip breaker, which communicates with other important systems like security and fire suppression. These systems tell the breaker when to trip without triggering either of the thermomagnetic elements, and is essential for some of the emergencies that can happen in restaurants and factories etc. Another type is Electronic or “smart” breakers, which are designed to fit into a panel that is connected to a computer system so it can be controlled remotely…
