What’s the main purpose of MCB, RCCB, and RCBO devices?

  1. Miniature circuit breakers (MCB) – provide you with adequate overcurrent and short-circuit protection.
  2. Residual-current circuit breakers (RCCB) – provide protection against residual current or earth fault currents.
  3. Residual-current circuit breaker with overcurrent protection (RCBO) – capable of acting as the only protective device in the circuit.

 

When you ask an electrical company in the Philippines for a device for your final circuit protection, they’re going to have you choose among three items: MCB, RCCB, and RCBO. This could leave you stunned and confused but that isn’t the end. They could also ask you to choose from a bewildering array of sizes and types which is sure to make your head spin.

Although you could easily get out of the situation by asking them which is the best for your situation, it’s better if you are aware of the purpose of each device. These devices are often used in modern electrical installations and you’re going to have to learn about them at some point, especially if you’re a new property owner who’s preparing to build a new home, so why put that off for later?

In this article, we’re going to identify and explain the purpose of each device. As an electrical company in the Philippines, we have the expert knowledge so stick around to find out more!

 

Miniature Circuit Breaker (MCB)

Miniature circuit breakers

The most basic circuit protection device among the three is the miniature circuit breaker (MCB). An MCB immediately disconnects a fault current in order to protect cables and equipment that are downstream of the protective device. Its main purpose is to provide you with adequate overcurrent and short-circuit protection.

Overcurrent is when a current load goes beyond the safety rating of an equipment or the ampacity of the conductor. Short-circuit isn’t that different and refers to the excessive flow of current along an unintended path with little to no resistance. These two are electrical hazards that may cause appliance and equipment damage, physical injury, and electrical fires—this is why it is important that they be avoided at all costs.

MCBs are more commonly used as replacements for old fuses and low voltage applications. However, there are times when an MCB is partnered with an RCCB—these two combined offers you more protective characteristics.

 

Residual-Current Circuit Breaker (RCCB)

Residual-current circuit breakers are the complete opposite of MCBs because they only provide protection against residual current or earth fault currents—as in the current flows into the earth. Since they cannot detect nor provide any kind of defense against overcurrent and short-circuits, they are never used alone. Most of the time, they are installed along with MCBs to perfectly satisfy the deficit; however, a fuse could be used, too.

Although different, it offers the same kind of benefits as the MCB which is protection against electrocution and electrical fires (only with better accuracy and efficiency). The reason for this is the fact that earth leakage currents are more likely to cause electrical shocks, faults, and fires while overcurrent or overload mostly damages appliances and equipment.

Again, much like MCBs, these are ideal for domestic and small-scale commercial applications but can still be used for larger applications depending on the type you choose.

 

Residual-Current Circuit Breaker with Overcurrent Protection (RCBO)

Residual-current circuit breaker with overcurrent protection

If you need or prefer a device that protects you from all three instances—overcurrent, short-circuits, and earth fault currents—then you may want to go with the residual-current circuit breaker with overcurrent protection (RCBO). Unlike the RCCB, the RCBO is used alone and is capable of acting as the only protective device in the circuit.

Out of the three, the RCBO is the most effective and reliable protective device but it does come with its own downsides. One is that there is a very limited number of types available and all of them have non-customizable characteristics or features. Another is that they cost a lot more than the other types but their performance should more than compensate for this. There’s also the fact that they are often larger, therefore, harder to install but that disadvantage is expected to be obsolete once compact RCBOs take off.

Admittedly, the RCBO is more commonplace in commercial buildings. Most real estate developers prefer using RCBOs as it gives them an absolute guarantee that their customers will be kept safe from electrical hazards. Examples of establishments that use RCBOs are Okada Manila and Robinsons McKinley Park Residence—two big names and contenders in the commercial real estate industry.

With that said, an RCBO can also be used in residential establishments and common houses and is actually gaining popularity among homeowners because of its amazing benefits and features.

Meiji Electric Philippines Inc. has a complete line of MCB (Miniature Circuit Breakers) ranging from 6KA (C45N) to 10KA (JVL16-63 & NCH100H) Interrupting Capacities. Our MCB are widely used and can be found in different DIY shops notably ACE HARDWARE, HANDYMAN, CW HOME DEPOT and the like. Our MCB’s are also used in many notable projects such as DE YMAZ Projects, BRIA HOMES, NEW APEC Dev. Corp, BORLAND Dev. Corp, etc. MCB can also be seen in major buildings like INOZA TOWER, FRABELLE II, FRABELLE Corporate Plaza, BELLEVIEW BOHOL BEACH RESORT and many more.

As for RCBO, Okada Manila, as one of the grandest hotel & casino here in the Philippines is using our Meiji‘s RCBO, This proof that Meiji electric is trusted to ensure the safety of electrical devices and circuit of Okada Manila.

 

Key Takeaway

Over the years, fuses were believed to be the most optimal device for final circuit protection but that changed when circuit breaker technology was introduced sometime during the 1970’s. From then until today, the principle of circuit protection devices has centered on these three devices—MCB, RCCB, and RCBO.

The purpose of these devices is simple and straightforward: they were made to reduce the risk of electrical hazards in the best way possible. The only difference lies in their capacity to do so with the RCBO coming out as the best one!

What are the safety benefits of installing ground fault circuit interrupter (GCFI) outlets?

  1. Prevents electrical shocks
  2. Puts a stop to electrical fires
  3. Saves electrical devices from damage

 

If you haven’t yet heard of ground fault circuit interrupter (GFCI) outlets from some other electrical company in the Philippines, friends, family, or acquaintances, then you’re in luck because we are going to tell you about it in this article!

GFCI outlets are protective devices that help prevent a number of electricity-related incidents. Unlike standard receptacles or regular outlets that simply allow electricity to flow from your supply to whatever device is plugged in, GFCI outlets are fitted with special features. It has the ability to constantly and continuously track the flow of electrical current in a circuit.

Once it senses any real-time fluctuations and changes that are out of the ordinary, it makes changes accordingly. If need be, it can and will cut off the flow of electricity in the circuit. For example, when you drop your plugged-in hair dryer into a water-filled sink by accident, the GFCI outlet will detect the interruption and immediately cut the power supply, avoiding any injuries and incidents.

Installation of GFCI outlets is included in the Philippine Electric Code (PEC) but not a lot of Filipinos are complying perhaps due to lack of knowledge regarding the product and its benefits, so we aim to change that today. Listed below are the three safety benefits that you can get when you install GFCI outlets in your home:

Prevents Electrical Shocks

Prevents Electrical Shocks

No matter how strategically placed your outlets are or well-maintained your appliances and devices are, the risk of electrical shocks and electrocutions is always there. The danger is even bigger if you have kids or pets at home who are more prone to such incidents. Slight contact with live wires and metallic surfaces may cause severely damaging shocks.

The only way to rid of this ever-present problem is to replace your old outlets with GFCI outlets. As said previously, these outlets have the ability to detect electricity flow and cut it off in case of fluctuations and abnormalities due to loose wires or any other defects.

Electrical Fire

Puts A Stop to Electrical Fires

In addition to sensing changes in the electrical current, GFCI outlets can also detect ground faults. As the name suggests, ground faults happen when the electrical current, on its way to its source or destination, travels through the ground and not using its intended path. These are one of the most common causes of electrical fires along with other types of electricity leakage and can be difficult to detect using normal means.

Although there are electrical fuses that provide protection against electrical fires, they aren’t fully fool-proof. Adding GFCI outlets into the equation can practically reduce the occurrence of electrical fires to zero and save you and your loved ones from harm.

Broken Outlet

Saves Electrical Devices from Damage

Aside from electricity leaking into the ground, it can also leak into your appliances and cause irreparable damage without your knowledge. Electrical leaks are hard to avoid and are bound to happen over time because they are caused by the deterioration of insulation. You can easily detect leakage if the appliance’s body is made of metal. In that case, you will experience an electrical shock every time you touch it – not an ideal way of detecting a leak, but it’s the only one.

If, on the other hand, the device or appliance is made from some other material, there is no way to know of the leak and excessive amounts of electricity will continue to flow into your equipment, causing damage. This is actually one of the most common reasons for device and appliance failure and is very hard to prevent, at least without a GFCI.

With a GFCI outlet installed, you won’t have to worry about electrical leakage. Additionally, since no damage is done to your devices and appliances, you can expect them to have a longer life expectancy.

Key Takeaway

Not a lot of people know about ground fault circuit interrupter (GCFI) outlets, which is a shame because they offer so many benefits that any local electrical company in the Philippines would advocate for.

They can prevent electricity-related accidents from happening and not only in the home. The benefits that a GFCI outlet offers extend beyond the household and applies to establishments and corporations. In fact, these large infrastructures may benefit most from this type of outlets as they don’t have control over each person who plugs in their devices. So, if you’re thinking of rewiring an existing establishment or building a new one, consider putting in GFCI outlets.

Sure, they may cost a little more than regular outlets but not in exchange for nothing. You are basically protecting people from common hazards that you would otherwise face on a daily basis. On top of this, it also allows your appliances and devices to live longer lives. Fewer repairs and replacements can mean more money saved, so, technically, GFCI outlets also allow you to keep your money in the bank.

How can you avoid electrical hazards during the rainy season?

  1. Have your electrical fittings checked prior to the rainy season
  2. Clean and upgrade your appliances.
  3. Avoid doing electrical chores.
  4. Ensure your home is grounded.

 

There’re a lot of reasons to love the rainy season – gone are the heatwaves that cause inconveniences and casualties along with the need to keep your air conditioners running 24/7 and your unending desire to go to the beach to cool off. While people are taking comfort in the natural and cold breeze that the monsoon brings, somewhere in the Philippines, an electrical company is set and dedicated to devising a safety plan for the masses.

Companies and branches of the government concerned with health and safety are responsible for informing people of the dangers that come with the rainy season. Electrical companies, in particular, disseminate information regarding electrical hazards in order to keep their client base, as well as other people, safe.

Although accidents brought about by the combination of electricity and the monsoon are few and select, they still happen and they can be fatal. For you to be able to avoid these electrical hazards that occur during the rainy season, it is best that you follow the different ways we’ve listed below:

Have Electrical Fittings Checked

Have Your Electrical Fittings Checked Prior to the Rainy Season

Here’s an important safety precaution that is guaranteed to lessen your run-ins with electrical hazards – have your electrical fitting inspected by a professional. We’re all well aware that, in the Philippines, the rainy season starts sometime around June. Before that is several months of nothing but sunshine and scorching heat, which means there’s ample time to prepare our homes for the onset of heavy rainfall and floods.

During the dry season, it is recommended that you have your home’s electrical fittings checked and repaired (if needed) in order to decrease the chances of electrical shocks and other electrical hazards. A task of this caliber should be done by professionals like an expert from an electrical company in the Philippines.

Clean and Upgrade Appliances

Clean and Upgrade Your Appliances

On top of having your electrical fittings and systems inspected and repaired, we also suggest that you clean and upgrade your appliances especially the ones that you can’t do without during the rainy season. Appliances such as electric fans, refrigerators, and televisions are some great examples to consider in this aspect.

Heavy and constant rains are reasons for high humidity, dampness, and moisture, which, for the most part, are beneficial for everyone and everything except your electrical appliances. These things allow for the growth of fungus and mold – two of the things that could cause damage and increase the probability of electrical hazards such as electrocution. The only way to prevent this from happening is to clean your appliances constantly with a dry, clean cloth.

Aside from cleaning your appliances, inspect their parts for your safety. Make sure that the wires, plugs, and switches are in good, working condition. If not, consider having them repaired or replaced.

Avoid Doing Electrical Chores

Avoid Doing Electrical Chores

It should go without saying that electrical chores, especially outdoor ones, should be put off until the skies clear up. Unless you are a trained engineer, you should stay indoors and away from potentially dangerous electrical systems during a heavy rainfall.

As said before, the season causes moisture, dampness, and humidity and these could interfere with your work. Not to mention that fiddling with electrical systems that are drenched in rainwater is extremely hazardous.

While indoor electrical chores are less dangerous, they should still be performed with extreme caution, so make sure to take safety precautions before doing them. Additionally, avoid touching any electrical part with wet or damp hands as the slightest wetness could cause danger.

Make Sure Your Home is Grounded

Ensure Your Home Is Grounded

When people say they got grounded, it often means that they experienced a slight and non-fatal electric shock from touching a certain electrical part. However, what we mean when we say to get your home grounded is to connect the metallic parts from your appliances, types of machinery, and devices to an earth plate or electrode found underground.

Ensuring that your home is properly grounded lowers the chances of electrocution from accidentally touching an exposed wire, plugging in things or even switching them on and off. The practice may be foreign to you, so try asking an expert for help. Professional electricians should help with earthing or grounding your home and other tasks.

One such item that can definitely help ensure that your home is properly grounded is Meiji’s very own GFCI outlet: built to ensure that your home is grounded without any risk of injury or any life-threatening scenarios, especially during the rainy season!

Key Takeaway

It is important to remember that the rainy season doesn’t just bring cold winds and comforting rain showers but also additional hazards that could cause severe damage to our homes and to ourselves. The danger of handling electrical parts and appliances doubles when heavy rains start to fall, so it is imperative that you tread cautiously and wisely.

Aside from being aware of the risks, you should learn of ways to avoid them in order to guarantee your safety. There are a lot of precautions that are pretty common sense and we’ve avoided those. Instead, what we have here are ways that many people may not know of but are equally crucial nonetheless.

Once you’ve followed the things listed above, you’ll become less prone to electrical hazards and more alert to handle any consequences should accidents happen!
