Choosing the right electrical installation system can often be confusing, especially when you have to decide between inbow (flush-mounted) or outbow (surface-mounted) switches and power outlets. Both types have different features that affect the look of your room, safety, and installation costs.
This article will help you understand the differences, advantages, disadvantages, and how to install both types. By the end, you will be able to make the best choice for your home.
Understanding the Difference Between Inbow and Outbow Switches and Power Outlets
The main difference between these two types is how they are placed on the wall.
What is Inbow (Flush Mounted)?
Inbow switches and power outlets are electrical devices installed by embedding them into the wall. Only the cover plate is visible, sitting flush with the wall surface. The entire mechanism and wires are hidden inside the wall. Installation requires making holes in the wall to place a special junction box called a "dop" or flush box. This system gives a clean and minimalist look, making it the top choice for modern homes and new buildings.
What is Outbow (Surface Mounted)?
On the other hand, outbow switches and power outlets are installed on top of the wall surface. The entire device sticks out from the wall, including the wires which are protected by conduit pipes that also run along the wall surface. Installation is simple and quick, usually using a wooden base as a foundation. This method is perfect for older homes that you don't want to tear down or for semi permanent buildings.
Advantages and Disadvantages of Inbow vs Outbow Installation
Choosing between inbow and outbow requires considering several aspects. Here is a complete comparison:
Advantages of Inbow Installation
- Superior Looks: It gives a neat, clean appearance that blends with the wall, perfect for minimalist designs.
- Safe from Bumps: Because it sits flush with the wall, it is less likely to snag or get hit when you move furniture.
- Increases Property Value: Homes with flush mounted wiring show good build quality, which can increase the home's selling price.
Disadvantages of Inbow Installation
- Complicated Installation: It requires chipping into walls and creates dust. It is best done during construction or major renovation.
- Higher Cost: You need to pay for the flush boxes, extra materials, and higher labor costs.
- Difficult Repairs: If a wire inside the wall gets damaged, you will have to break open the wall to fix it.
Advantages of Outbow Installation
- Easy and Fast Installation: No need to break walls, making it suitable for homes that are already lived in.
- More Affordable: It uses fewer materials and the work is done quickly, saving money.
- Flexible: You can add new outlets anytime without damaging the walls.
Disadvantages of Outbow Installation
- Less Neat Appearance: The visible wires and protruding device bodies can make a room look less tidy.
- Prone to Being Hit: Because it sticks out, it is more likely to be bumped into.
- Gets Dirty Easily: The gap between the device and the wall can collect dust.
Inbow Installation Process and Techniques
Installing inbow devices requires careful planning and is done step by step.
Preparation Stage: Decide where you want your switches and outlets. Think about where your furniture will go. The standard height for light switches is around 120 to 140 cm from the floor. Power outlets are usually 30 to 40 cm from the floor.
Making Holes and Installing the Flush Box: Holes are made in the wall to fit the flush box. The box is then placed in the hole and leveled with the wall surface using a mixture of cement or plaster.
Installing the Mechanism and Cover: After the wall has been painted, the switch mechanism is installed into the flush box. Finally, the cover plate is attached to complete the look.
Outbow Installation Process and Techniques
Outbow installation is much simpler and faster.
Preparing Tools and Materials: Get your outbow switch or outlet, a wooden base, screws, wall plugs (rawlplugs), screwdriver, pliers, and conduit pipe to protect the wires.
Attaching the Base and Connecting Wires: The wooden base is attached to the wall with screws. Then, the outbow device body is mounted on top of this base. The wires are connected to the terminals inside the device.
Finishing with Conduit Pipe: The wires coming out of the device are placed inside the conduit pipe. This pipe is then neatly attached along the wall leading to the power source or light point.
Choosing between inbow and outbow really depends on what matters most to you. If you are building a new home or doing a full renovation and want a clean, modern look, inbow installation is the right choice. On the other hand, if you live in a finished home with a limited budget or need a quick solution, outbow is the practical answer.
