What do you need to know about the two types of transfer switches?

  1. The significant difference between manual and automatic transfer switches
  2. Advantages and disadvantages of manual transfer switches
  3. Advantages and disadvantages of automatic transfer switches


As a top electrical supplier in Metro Manila, we know more than a thing or two about transfer switches. For starters, they are necessary for homes or establishments that have more than one power source. Combined with these alternative power sources, they can save you from having to suffer through or lose revenue over blackouts and power outages.

You can pretty much guess what a transfer switch does based on its name: it’s a switch that transfers your electrical line from one power source to another – from the commercial power grid to a generator or backup battery for example. This continuous supply of power ensures smooth functions and high productivity in different organizations and industries. For households, it saves you from the devastating effects of losing power and not having access to your devices.

There are many kinds of transfer switches, but the two main ones are the manual and automatic transfer switches. Each one functions differently, offers a different set of advantages, and comes with their own disadvantages. To find out more and achieve a complete understanding of these types, simply continue reading below!

The Significant Difference Between Manual and Automatic Transfer Switches

Although both exist for the same purpose, the way they achieve their goal is quite different.

Manual transfer switches are the more basic of the two and rely on manual effort to function. As its name suggests, you, the owner, have to manually flip the switch if you want or need to change power sources. So, in the event of a blackout, you will completely lose power until after you get up, grab a flashlight, head over to where the switch is, and flip or push it. You also need to manually switch it back the instance your main power supply comes back on.

Automatic transfer switches, on the other hand, are more advanced and have additional features. They can monitor the power supplied by your main source and detect issues such as fluctuations and irregularities, which are signs of an upcoming power outage. These things prompt the transfer switch to start up the generator and redirect your power line to it as soon as it becomes stable. What this means is that there is little lag time between losing power and changing sources, meaning you only lose power for a second or two – sometimes not at all.

Advantages and Disadvantages of Manual Transfer Switches

Now that we’ve discussed the difference between the two, we need to talk about each one’s advantages and disadvantages so you can figure out which is the right one for you, and we’ll start with the manual transfer switches.

The main reason some people prefer manual transfer switches over automatic transfer switches is that they’re much cheaper than the automatic ones. They are also small in size and can fit anywhere, making them beneficial to establishments that have limited space. Moreover, installation can be done by almost anyone who has basic skills and can properly follow instructions.

Of course, they also have downsides, with the most obvious and prominent one being the fact that you have to manually flip the switch. It’s nothing but a slight inconvenience for households but a few seconds of downtime can be detrimental for some businesses. For this reason, manual transfer switches are usually used by homeowners or by small businesses who aren’t troubled by brief power losses.

Advantages and Disadvantages of Automatic Transfer Switches

Likewise, automatic transfer switches also have their own advantages and disadvantages.

The biggest advantage of using an automatic transfer switch is simply the fact that everything is done automatically and no manual labor is needed. Before the outage even begins, the transfer switch will start working and prepare your backup power supply for use.

By the time the outage rolls in, your power supply would have already been transferred to your backup and not a single moment is lost. Large businesses are the ones that benefit the most from this as they won’t lag behind or lose money the moment the commercial power grid fails.

As for its disadvantages, the main one is its price. Since they’re so high-tech and advanced, they naturally cost way more than manual transfer switches. Another reason is size; if manual transfer switches are small, automatic transfer switches are large and require a lot of space. Lastly, installation is complex and a professional is required to accomplish it, which costs extra money.

Key Takeaway

All this information should be enough to make you decide on whether or not you need transfer switches and what kind to get. In general, there is no better one among the two. However, if you take into account your business’ or household’s needs and capabilities, you should be able to see that one is the more practical choice.

Once you’ve arrived at a decision, don’t hesitate to head to an electrical supplier in Metro Manila and purchase your very own transfer switch. You may even want to ask them to install it for you in order to guarantee proper and safe installation!

Ever wondered why some plugs have 2 prongs while others have 3? Well, it is all about safety!  Electricity must flow in an uninterrupted circuit. Electrocutions often occur in homes due to defective products, such as appliances, power tools, and improper wiring. Children are particularly susceptible to electrocution not only because of their never ending curiosity but also because they can sense an electrical current as low as 0.006A (6mA). Faulty installations or repairs can also result in electrocution and are a primary cause of electrical accidents at home.

Take a look at your home outlets for instance, the right smaller slot is for the HOT wire, this is where electricity comes from; the left wider slot is for the neutral wire, this wire completes the circuit and feeds the electricity back into the system.

Implement this idea into a larger power distribution system and you’ve created a huge problem. If excess voltage is applied to the circuit, like a lightning for example, all the excess energy must travel through your electrical network, potentially exploding everything connected to it. To prevent this, a third ground wire is connected straight to your breaker enclosure and is driven straight to the earth. Now when a lightning strikes into your system, the excess energy is directed into the land instead, but we have now created another problem. Before all of this, the only way to be shocked is when you touched both the neutral and hot wires, in that case your body would close the electrical circuit and the voltage would travel through you, from one wire to the other. Now, because of grounding, half of the electrical system is always indirectly connected to you, through your feet. Meaning you only need to touch a single wire or a metal object electrified by one to become an unfortunate circuit. This is why some appliances have the third prong. It is a safety feature for devices with metal cases. It protects the items from wear and tear, aging and faulty manufacturing. A hot wire from within the appliance could come loose and make contact with the metallic case, without the 3rd prong, you could be lethally shocked when touching it. Appliances with this third prong have a wire that connects directly from the metallic case and back to the outlet. Voltage along this path would trip the breaker and cut off the electricity that could potentially kill you.

Electrical Safety with Meiji Products

Prevent serious injury or an accident from happening in your home by using Meiji GFCI’s, AVRS (Automatic Voltage Regulator), UPS (Uninterrupted Power Supply), Wiring Devices, Extension Sets, and Timers which all have grounding or 3rd prongs.  The whole family of Meiji Electric’s GFCI’s MGU252MGF250GF250 and LG20 are classified as Class A in accordance with UL943. This is because all Meiji Electric GFCI’s have a 6mA sensitivity rating, unlike other GFCIs being sold in the markets which only have 15mA rating or even higher. UL Standard indicates the `let go factor’ of women and children should not be more than 6mA sensitivity rating because anything above this range is where `freezing currents’ start and it may not be possible to `let go.’ The Meiji GFCI is different from conventional receptacles, because in the event of a ground fault, it automatically trips, and stops the flow of electricity to your body, thus preventing serious injury. Meiji GFCI’s will work even without a grounded wire, even if a utility box isn’t grounded, installing a GFCI in it will still protect you (and your tools and appliances) from ground faults. The Electrical Code requires installing a GFCI for all wet areas, this is necessary to avoid ground fault which happens when electricity passes through our wet body before it reaches the ground.






Our newest addition is the MGU252, the only square GFCI with a combination of 1 international outlet and 2 USB outlets. It is designed for ease of use with all USB-dependent gadgets and devices while protecting you in wet prone areas. For your convenience, we will be giving a FREE custom-made 3’’x 3’’ utility box UB-252 so you don’t need to worry on where to get one.





So the next time you see that 3rd prong, just remember that it could save your life! Call us at 448-7423, 727-5790, 414-4012 and 413-6636 or email us at sales@meijielectric.ph for your various electrical requirements! You can visit our showrooms located at Unit 15 Landsdale Arcade, Mother Ignacia, Quezon City and 1 Mabolo Street, New Manila, Quezon City. You can also buy our items at your nearest ACE Hardware, Handyman or Ortigas Home Depot branches.

It’s no secret that one of the biggest concerns homeowners have, or at least should have, is how to make everything in your household last as long as it could. Some people think in order to save, you must purchase cheap appliances. Others think it would be better to buy the more expensive appliances in order for them to last. But here’s a little secret: a higher price doesn’t always mean longer life expectancy.

Good guy electrical suppliers in the Philippines will tell you that in most cases, the longevity of appliances, gadgets, or any item depends on its usage!

Don’t believe us? Try out these tips to help maintain your home appliances!

Keep Them Inside and Away from Windows


Place your home appliances anywhere but right beside or in front of the windows, especially if the windows are often wide open or there are no curtains. This will keep them safe from direct sunlight which can overheat any piece of machinery. Worst case scenario is that it gets rained on and damages the equipment!

Regularly Clean Your Appliances


Your appliances may differ from each other in many ways, but all of them need to be cleaned regularly. For example, cleaning the base grill of your refrigerator often will help improve air flow to its components. Dust off the compressor coils at least once every six months in order for it to cool your refrigerator efficiently. In addition, wipe down the refrigerator door seals whenever they get sticky. According to Ryan Huntley of RepairClinic.com, a thin layer of petroleum jelly on the seals will make them last longer. Don’t forget to remove, clean, and return the drip tray every couple of months.

As for microwaves, don’t leave the food particles in there for too long. These particles can turn into carbon, which can cause electrical sparking that can damage your appliance. One way to clean the inside of the microwave is by heating up a glass of water (microwave-safe glass of course), and wait for the water to boil. The steam will help soften and loosen the food particles inside. Afterwards, use a cloth, dishwashing soap and water to clean remove the food residue.

The filters in air conditioners need to be cleaned every 225 to 360 hours of use—that is, around every 9 to 15 days of operation. Use a damp cloth and soap to clean off the filters.

Don’t Overuse Any Appliance


Appliances are technically slaves to its owners, but they shouldn’t be treated as such. Keeping your house in tip-top shape is a joint effort, meaning you shouldn’t skimp on your share of the workload! For starters, never overload the washing machine in an effort to hasten the laundry washing process up. This is likely to wear out the unit’s motor and drive belts. There will always be a maximum capacity recommended by its manufacturers, depending on the appliance, which should be followed. The same goes for dryers.

If you follow these tips, there is a higher chance you’ll be able to use your home appliances for a little bit longer. If you have comments, suggestions, or stories to tell, don’t forget to share it in the comment box below!
