It is an obvious fact that we Filipinos have to get ready for tropical storms especially during the months of June to September. Not only the recent Tropical Storm “Mario” caused a deluge in Metro Manila, it also exposed and highlighted dangers for us.


A medical student at the University of Sto. Tomas and a hotel employee died after being electrocuted along  España Boulevard in Sampaloc, Manila on Friday, September 19, 2014.

The first victim, 22-year-old student, was electrocuted at around 2 p.m., in the middle of the flood in the area. On another place, the second victim, was electrocuted at around 7:30 p.m., while he was passing through Maceda Street at the corner of España Boulevard.

According to a report by a police officer, first aid responders from the Metropolitan Manila Development Authority (MMDA) tried to revive the first victim and brought him to the UDMC Hospital where he was declared dead. The other victim on the other hand,was seriously injured.

If only these areas acquired a breaker which can prevent ground faults, this incident would have been avoided. We in Meiji adhere the importance of having protective circuit breakers.


Earth Leakage Circuit Breakers

Earth Leakage Circuit Breakers (ELCBs) are protective breakers of high performance when it comes to preventing ground faults and short circuits. When an imbalance of 30, 100, 200, or 500 milliampere is detected, ELCB automatically cuts off the power line to prevent further damages. It can even detect small stray voltages on the metal enclosures of electrical equipment, and interrupts the circuit if a dangerous voltage is detected.

High quality ‘LS’ brand ELCBs from Korea

Meiji Electric carries high quality ‘LS’ brand ELCBs from Korea. Available from 15 to 800 amperes, Meiji Electric can supply you with the load you require. Small businesses can benefit from the protection given by ELCBs. Employees and customers can be protected from very dangerous ground faults which may cause injuries or worse, death, just like what was stated from the news.

Utilized by large industries

ELCBs are best to be utilize by large industries particularly those which involve wet working areas. Research laboratories, resorts, water irrigation companies, water parks and other related industries can benefit from the protection given by ELCBs. Large industries use ELCBs to distinguish high sensitivity current operated 3 phase devices that trip in the milliamp range from traditional 3 phase ground fault devices that operate at much higher currents.

For high reliability ground fault protection, upgrade now your breakers to ELCBs. Accidents may happen anytime. An advanced prevention is always better than prepared remedy. Don’t hesitate to invest for safety. At the end of the day, you wouldn’t want to risk your life for such accidents.

20140527_101356Many people do not know what is an RCBO. And because of this, we, in Meiji Electric, can help you understand the basic functions of an RCBO, so you can handle safety electrical measures at home without paying for the services of an electrician.

RCBO, also known as Residual Current Circuit Breaker with Over-Current Protection, is an extraordinary circuit breaker with three main functions:

  1. To detect residual current due to ground fault
  2. To detect overload or over-current on a circuit; and
  3. To protect against short circuit

Safety purposes against ground faults

Electrical experts will install an RCBO for safety purposes against ground faults which can kill people, especially to those homes and establishments which are most likely to operate in wet areas like bathrooms, kitchens, swimming pools of resorts, water parks, etc.  Another purpose is to prevent an overload on a specific circuit, thus, preventing accidents like fire, etc.

Detect a current imbalance

An RCBO will detect a current imbalance and an overload using the same interrupting method. They call it a ‘trip’. It works almost the same as Ground Fault Circuit Interrupters (GFCIs), cutting off the current when ground fault happens or when there is any current imbalance, thereby, protecting our lives. If current flow is not equal, it means that there is a current leakage to the ground, which could possibly mean someone is touching or has accidentally touched the live conductor of an appliance as they are attempting to use it, in this case, the RCBO will break the circuit or trip.

Ratedd both by the normal current that are expected to carry, and the maximum residual current that they can safely interrupt

RCBOs are rated both by the normal current that are expected to carry, and the maximum residual current that they can safely interrupt also known as the sensitivity rating. It is also designed to interrupt a current overload in a circuit. This may happen when more appliances are being used beyond the rated current. A short circuit is an abnormal low resistance connection between two wires of electrical power to any circuit. A good example is when the cables of your electrical appliances are worn out and the live wires are connected improperly. This too can be detected by the RCBO.

Meiji Electric offers you RCBOs of high quality performance

Meiji Electric offers you RCBOs of high quality performance that would surely protect your life from deadly electrical harms. Meiji RCBOs have rated currents of 3, 6, 10, 16, 20, 25 and 32 Amperes. They also have a short circuit interrupting capacity of 3000 Amperes. Meiji RCBOs have sensitivity ratings of 30 mA, 100 mA and 300 mA with very safe levels of interruption. When this level of sensitivity is detected by the RCBO, it will automatically trip and will break the circuit to prevent further damages. Meiji RCBO has a built-in test button, and should be tested monthly to make sure it is functioning properly.

All houses and offices have the possibility of experiencing current imbalance

We cannot escape the fact that we might get killed with these electrical problems. Having this information, we realize the importance of using an RCBO, and should consider it to be a “must have”.

For some simple electric precautions, you don’t have to spend money for an expert’s service. We, in Meiji Electric, shall continue to enhance energy, to help you understand electrical safety measures, and provide an easy and convenient way for your overall safety.

Meiji Transfer SwitchesUnlike the conventional “Double Throw Switch”, ‘Meiji’ MTS is a compact, light-weight and very user-friendly Manual Transfer Switch with a built-in interlocking system that mechanically interlocks the Normal (MERALCO) from the Emergency lines (GENSET). Turning on the Normal side breaker will automatically switch off the Emergency side. On the other hand, the Normal side will have to be switched off first before the Emergency side can be switched on.
