Every building should have an electrical wiring system that’s up to code. In fact, it’s a requirement for every building that is to be built. People rely on a fully-functioning electrical system to power up all the appliances in their houses and offices. It basically allows you to take advantage of the various technologies that make our lives more convenient. Every electrical company in the Philippines ensures that the electric wiring in every building is installed perfectly, to prevent any kind of electrical problems from within the walls.

There are also certain devices that help electricity flow from the power source to the establishments as efficiently as possible. Circuit breakers and panelboards are some of the most essential ones, but there are a number of optional choices that can further enhance and even protect your establishment from malfunctions and damages.

One of the more notable devices is the manual transfer switch—emphasis on its manual nature because it has advantages over its automatic counterpart. That being said, what exactly does it mean to install a manual transfer switch in your building?


How Does a Manual Transfer Switch Work?

How Does a Manual Transfer Switch Work?

For most people in the electrical industry, these types of switches are one of the best and simplest solutions to keep the establishments powered during a power outage. This lets your business or your home continue to function without any setbacks.

Manual transfer switches are usually mounted on the interior or exterior of a building. Most of the time, it’s placed near the main circuit breaker or panel board. When the establishment’s electrical supply is interrupted, you can connect a portable generator to the manual transfer switch to provide a more reliable source of power while the disruption is still ongoing.

These switches work by isolating circuits you want to be powered in the event of an electrical shortage or outage. Once the circuits are secluded, the switch swaps your access to grid power for generator power.

This intricate yet simple system makes the transfer switches in general extremely safe while also quicker to operate than when you connect a generator directly. Meiji brand Manual Transfer Switches has the added feature of being able to delegate electricity to specific circuits!


Increased Electrical Security and Safety

In general, manual transfer switches are installed in establishments for very specific reasons. However, these aren’t as urgent as the usual functionalities that other, more common electrical devices provide. Keep in mind that you should also only install transfer switches if you have an emergency power generator. Without one, you won’t really make use of the transfer switch that much.

That being said, manual transfer switches are essential for small to medium establishments, particularly commercial buildings that consume a lot of electricity. Malls and office buildings benefit from manual transfer switches a lot because they heavily rely on ensuring their operations are always fully powered. It’s highly recommended that commercial buildings, complexes, and other areas that need a lot of electricity should have a manual transfer switch just in case there’s an unforeseen power outage.

In essence, what manual transfer switches truly provide to an establishment are safety and security. Safety in the context of always being protected from power outages and damages to appliances as caused by unnatural electricity flow. This is fairly important, especially for appliances that have sensitive electrical systems. Of course, you can still install things like GFCI Receptacles or uninterruptible power supplies to further protect your appliances, but it’s a good idea to have protection at the very start of the circuit.

It also provides a way to secure a quick alternative to when there’s a power outage. With just a flip of a switch, you can change your electrical supply from the grid to your power generator! The best part is that you won’t have to do anything complicated to both the generator and the circuit breaker! The manual transfer switch is installed as the buffer between them.

Advantages of Installing a Manual Transfer Switch

Aside from the basic functions of a manual transfer switch, one other reason to install one in your establishment is that it provides a few advantages over its automatic counterpart.
Manual switches make it easier to control loads. You can choose which one of your electrical circuits can be powered at a time. You can also control the load that your generator is under to prevent overloading!


Key Takeaway

Manual transfer switches are vital in every establishment that needs to be continuously running. This has been evident with the success of Meiji Electronic’s various projects in collaboration with Irma Fishing Trading Inc., Gloria de Dapitan (Dakak Beach & resort), Moldex Realty Inc., Cityland Development Corp., and Torre Venezia.

It helps prevent loss of productivity when there’s a power outage, but more importantly, it ensures that your establishment is well-equipped against power outages and other possible electrical interruptions.

As technology continues to advance, some might neglect the natural energy we can get from Mother Nature. To be significant, we should utilize what has been naturally entrusted to us and at the same time, enjoy the perks we can get from our natural resources.

Renewable Energy

rERenewable energy, as defined by Wikipedia, is the power that comes from resources that are naturally replenished like sunlight, wind, rain, tides, waves and heat energy stored in the Earth.

Renewable energy substitutes the usual fuels we use in running motors, energy services and electricity generation. The mainstream renewable energy sources are wind power, hydropower (energy in water), biomass (energy from plants materials), geothermal energy (energy stored in the earth) and solar energy.

And because it is widely used all over the world mainly in power plants, business establishments and even in our homes, it results to significant energy security, climate change treatment and a lot of economic benefits.

There is a strong support of promoting renewables sources particularly solar power and wind power. These kinds of energy source provide 19% of electricity generation worldwide including households.” -International Public Opinion Survey

Growth of Renewable Energy

According to the Renewables Global Features report last year, 2013, national renewable energy markets are projected to continue to grow strongly in the coming decade and beyond. Here in the Philippines, specifically in Palawan, there will be a large micro-grid power plant generating clean renewable energy.

Some local residents nationwide have renewable energy technologies (Solar Panels, Wind turbines, etc.) already. With these advances, it would be cost-efficient  for you to have another source of power aside from the usual distributor of electricity power (MERALCO).

You can definitely use renewable technology with or without generators as a substitute for emergencies especially when you experience power outage in a home.

Manual Transfer Switch1

As we are informed, we cannot use both emergency power and normal power (MERALCO) at the same time, or else, it would start a fire or even blow out a house.  In this case, a Transfer Switch is a necessity.

Transfer Switch Utility

With the help of a transfer switch with a built-in interlocking system, may it be manual or automatic transfer switch, we can easily transfer power from one source to another safely.

Meiji Electric offers three types of transfer switches, Manual Transfer Switch (MTS), Automatic Transfer Switch (ATS) and Contactor Transfer Switch (CTS). With MTS and ATS, you can make your home more comfortable during  brownouts. The type of transfer switch that would match up with your generator and/or renewable technology depends on their capacity and ampere ratings.

Normally, we use any of the three in a household setting. But for institutions with industrial setting, like power plants, the MEIJI Automatic Transfer Switch (ATS) is the appropriate one to use. An ATS, by the term itself is a system that automatically transfers your emergency power when normal power is unavailable and automatically transfers back to normal power when power returns. This type of Transfer Switch brings ease and security to you because you don’t need to turn on and off any power source by yourself.


Some home owners find it more convenient to use Meiji Contactor Transfer Switch (CTS). CTS is a transfer switch that brings the accessibility of utilizing the same feeder lines during emergency power, with a current-limiting device that can help you regulate the amount of energy to be given each specific load when the power runs out.

It has an automatic transfer switching which safeguards you and your home from overloading the generator with a current-limiting and automatic resetting of power at your pre-set time.

You can make your home safe and comfortable during a power outage and peacefully enjoy bonding time with the family. The same with corporations, they can work continuously without being interrupted by energy disconnection and other sudden electrical cut-offs. Remember that down-time costs double, you pay for regular work without producing anything.

Technology can really make people’s lives easier without harming the environment.

Thus, Meiji Electric responds to everyone’s needs as we all embrace its continuous development. With Meiji, go along freely with the flow of innovations on green energy.

Manual Transfer SwitchWhat is a Transfer Switch? I bet if you’ve been living for a year in the Philippines, you’ve experienced at least once… nah, I’ll be kind to say at least thrice – of having power shortage or what we would normally call, “brown-out!” So when it happens, you slowly reach out for your handy emergency light to finish whatever it is that you’re doing. But what if you’re cooking using an electric stove when the power got cut? How do you continue? Or when you were watching a really nice movie and the hero was just about to save the day! You were left hanging because of the power outage – what do you do? How do you respond to your kids who desperately need to finish their homework with a strict deadline the next day? Answer: GET YOURSELF A TRANSFER SWITCH!

When we say ‘transfer switch’, we mean transferring power from one source to another. So we can say, from using Meralco power source, we now transfer source to your Genset or Generator. Now, having said this, we can get the logic that you can only make your transfer switch work when you’ve already bought yourself a reliable Genset. In choosing which Genset to buy, you first need to establish what percentage of Meralco power you need or want to work during a power outage. If this is inconvenient for you to compute, then you may just check what loads: wattage and ampere ratings of the appliances you need or want to work. After doing so, then you’re all set for your transfer switch.

Double Throw Switch

Transfer SwitchesNow you may say what about the conventional “Double Throw Switch” that my friendly engineer-technician recommended? Well, aside from it’s unappealing in nature and the need to move the lever up or down; it merely makes up of a barrel bolt that highly risks your (the users’) safety. What do I mean? In light of a transfer switch features, let me help you understand.

A transfer switch is a compact, light weight and very user-friendly mechanical device with a built-in interlocking system that does not allow you to switch on both your Normal power source (MERALCO) and the Emergency line (GENSET). Turning on the Emergency side breaker will automatically switch off the Normal side avoiding any faults on your power source that may cause extensive damage such as fire, explosions and the like to your main panel board. On the other hand, the Emergency side will have to be switched off first before the Normal side can be switched on. This will then be an advantage of the so-called Manual Transfer Switch (MTS). These are available in 2×1 pole, 2×2 pole, 2×3 pole, with models starting from 1A. How about the price you say? As we have already mentioned earlier, your Genset will depend on the loads you want or need to work therefore, the Transfer Switch also depends on the load of the Genset you’re using. So ultimately, the price depends on you. So now, be sure to inform your engineer-technician that you’ll definitely be using a Transfer Switch than a Double Throw one.

Now that you know how to choose your Transfer Switch, how it works and its basics features from the MTS earlier, allow me to inform you of the two other types. Don’t worry, I’ll only brief you into them at least before a sales agent pitches in his or her talk, you are not at their mercy.

Automatic Transfer Switch

An ATS by the name itself is a system that automatically turns on your Emergency Power when Normal Power is out and automatically shuts off your Emergency Power and turns on Normal Power when it comes back in. This type of Transfer Switch highlights convenience and safety for you (the user) as you don’t need to personally turn on or off any power source. And more importantly, like the MTS, it avoids accidentally turning on both power sources.

An ATS is a Circuit Breaker type that is electromechanically operated that does that for you since there is an electromechanical circuitry unlike the normal breaker in your bathroom heater that you have to manually turn on and off. You would just have to fix the loads set on your Generator for emergency purposes.


Contactor Transfer Switch (CTS)

Last but definitely not the least is the Contactor Transfer Switch (CTS). Like the ATS, the CTS’ primary role is to promote safety by automatically turning on and shutting off your Genset in cases of power outages. Its primary feature we can say is convenience. Aside from the above-mentioned, it also allows you to turn on all the loads you want your Genset to give power to. This is because of its current limiter that can detect overloading. So your CTS saves you the hassle of memorizing which breakers are the only ones allowable to turn on, the stress of turning off all breakers and turning them on again once power is back, instead when it senses an overload, the breaker just ‘trips’ or cuts off power. At first, you have to do a trial and error to find out up to how much your Genset can handle. But once you’ve established that, when power is out or comes back, you’ll just have to wait about 3-5 minutes for the delay. This is to protect your breakers from the electric surge when power comes back. So once this has been established… then clap, clap, lights on!

So whether you were cooking a romantic dinner for your spouse, watching a great movie with the family or in desperate cramming mode to finish your homework, when the power gets cut, no worries! You know you have a Transfer Switch doing its work!
