A Junction Box is a box made of plastic that is designed to house and protect electrical connections such as wiring splices. This box serves as a safety measure that stores and shields electrical components to prevent contact with live wires which in turn reduces the risk of electrical hazards. They come in different sizes, materials, and variations, providing a secure and organized space for managing electrical connections while also complying with safety codes and regulations.
Junction Box Prices
The price of junction boxes differs depending on their sizes, functions, and their brands. Some go for as low as ₱11.00 while other junction boxes could go up to more than ₱240.00.

Advantages of Junction Box
Safety – One of the primary advantages of junction boxes is their safety. These boxes help provide a space that helps protect electrical connections to prevent any accidental contact with live wires to reduce the risks of electrical shocks or fires.
Organizing of Connections – Junction boxes organize and contain electrical connections, reducing the likelihood of loose wires or exposed conductors. This box helps maintain the integrity of your electrical system and helps in facilitating the troubleshooting and maintenance to make them easier.
Prevention of Environmental Damage – Junction boxes protect electrical connections from elements such as moisture, dust, and debris which is important for maintaining the reliability and longevity of electrical systems.
Disadvantages of Junction Box
Lack of Space – In some situations, the size of a junction box may also be a disadvantage, especially in more confined spaces or installations where a compact design is required.
Heat Buildup – In cases where electrical connections generate a lot of heat, the lack of ventilation in the junction box could lead to heat buildup which could potentially affect the performance and lifespan of connected components.
Installation Challenges – Installing junction boxes will require drilling holes to secure the box properly, and making accurate electrical connections which can be a little hard. Keep in mind that an improper installation of the junction box can compromise its effectiveness.
Cost – It is also important to note that high-quality, code-compliant junction boxes can be relatively expensive, especially in larger or more complex projects. Junction boxes add to the overall cost of an electrical installation which could also be a disadvantage.
