Panel boards in the Philippines are used for various electricals. These boards are where electricity is managed. Panelboards allow you to monitor the power being generated. There is a lot more you need to learn about these if you plan to buy your own set. Continue reading if you want to learn more about the nifty components of a panel board.


The definition of a panel board

Panel boards are also known as distribution boards. This is where your power is circulated and transmitted. A panel board also houses components that allow you to monitor how much power you’re making and more.

Another important job of a panel board distributing power. It can divide your electrical feeds into various supplementary circuits while also having a protective fuse for the circuits. The panel board is an essential centralized location for all major electrical functions such as generation, monitoring, and distribution of power.


Why are panel boards important?

Panel boards are important for a number of reasons. Starting with the basics, a building without a panel board can still function but it won’t be able to distribute power properly. A panel board is like the heart of a building. You’ll find many components within the board. It can be confusing at first, but a good electrical engineer can identify and fix any problem you encounter.

Another reason why you should have an electrical panel is to protect your electrical components. Electrical components left in the open will immediately deteriorate and get damaged if you’re not careful. Even things as simple as dust and lint can hinder your power. But the most dangerous is a simple drop of water, which can easily impact the entire structure.

Should you encounter short circuits and circuit overload, a panel board will protect you and anyone else within the vicinity. Every component stored in the panelboard is organized and protected. So when the time comes to fix it your electrical expert can get right to the problem.


Panel board components

Different panelboards come in various shapes and sizes. Some even require specialized handling. Typically there are some key components of a panel board. Here are some of the components you need to be familiar with:

Power circuit

This is a circuit that uses electricity in order to operate a load on the panel board. Closing the circuit causes the machine connected to it to start operations but breaking the circuit will stop the machine.

Control circuit

This type of circuit is used to control the various power circuits on the panel board. This can make sure that your machine and workers are safe in case of a short circuit.


A transformer is a static device that is used to transfer electrical charges between circuits. This will ensure that the power transfer is consistent without changing the frequency of the current.


Different panel board enclosures

Enclosures are also an important part of your panel board. Without this you won’t be able to protect your components from outside factors and elements. Here are the different enclosures you should familiarize yourself with.

Indoor enclosure panel boards

This is the first type of panel board that’s used to secure the electrical components from outside elements such as dirt, foreign objects and people. This type of panel board is not waterproof and water-resistant. It will most likely be knocked out if the end and conduit connections are compromised. This should be avoided in industrial environments.

Indoor and outdoor enclosure panel boards

This panel board is intended for use in indoor and outdoor situations without compromising the basic protection mentioned above. These are very resistant to water, rain, and even ice. If you need to use this it can be much better than the first type due to these inherent resistances. You get all these benefits while also protecting your panel boards from any potential knockouts.

Live component enclosure panel boards

Live components are dangerous and hazardous if you’re not careful. This type of enclosure is designed to protect personnel from electrically live components as well as the internals from dust and dirt. These are also splash resistant and can withstand hose-directed water. Warehouses that work with a lot of ice in low temperatures will enjoy this type of panel board.

Anti-corrosion enclosure panel board

This is similar to the previous type but with an added resistance to corrosion. These are made from stainless steel or non-metallic components. Food and pharmaceutical industries can run into a lot of corrosion in their panel boards but with this enclosure, it can prevent these problems. If you work in a humid area that tends to be cold as well this can be used as an alternative to the previous.

Standard enclosure panel board

In general, this will still keep people away from hazardous panel board components. This is designed for indoor use and has inherent protection against dust, lint, and dripping water. This panel board is great for domestic use and office use because of the basic protection it offers.


Key takeaway

Panel boards in the Philippines are key components in your electricals. It not only protects your components but it also manages your power. Without the panel board, you can face a number of problems such as overloaded circuits and short circuits. Invest in your own set of panelboards today.
