Back boxes are the containers that house the space behind electrical fittings such as power outlet sockets, plugs and light switches. They can be made from either metal or plastic. While [electric cables](https://hken.rs-online.com/web/c/cables-wires/electrical-power-industrial-cables/power-cable/) may be joined inside back boxes due to their convenient placement in the wiring system, their main purpose is to accommodate switches and sockets. They allow switches and plugs to be recessed into the wall for a better appearance and efficient storage of wiring components.

## **How to Choose Between Metal and Plastic Socket Boxes?**

When selecting socket boxes for electric installations, it's crucial to choose between metal and plastic options. The two common materials for back boxes are metal (aluminium, mild steel) and plastic (polycarbonate, other polymers). Each material offers unique advantages depending on the installation environment and requirements.

### **When to Choose Metal Socket Boxes?**

Metal socket boxes, such as those made from aluminium or mild steel, are often preferred for their robustness and durability. They offer superior protection against physical damage and are ideal for environments that require added security, such as industrial or outdoor settings. These storage boxes provide enhanced fire resistance and grounding, making them suitable for high-risk electric systems.

### **When to Choose Plastic Socket Boxes?**

Plastic socket boxes are a lighter, cost-effective alternative to metal. These boxes are ideal for residential or light commercial applications, where there is less exposure to harsh conditions. Plastic offers good electrical insulation properties, helping to prevent short circuits and offering ease of installation due to its lighter weight. Additionally, they are more resistant to corrosion, making them suitable for areas with high humidity or corrosive elements.

## **Common Back Box Mounting Options**
- **Fixing Clip:** The fixing clip mounting option provides a secure method to attach socket boxes to walls or surfaces, offering flexibility and ease of installation. It allows for quick adjustments and repositioning, making it ideal for spaces where future modifications might be required.
- **Flush Mount:** Flush mount back boxes are designed to sit neatly within the wall, offering a clean and professional finish. They are often used in spaces where aesthetics and a smooth surface are a priority, ensuring that the socket is level with the wall.
- **Surface Mount:** Surface mount back boxes are installed directly onto the wall's surface, making them suitable for retrofitting or areas where wall drilling is not an option. This option is ideal for quick installations or in spaces with limited access to in-wall cavities.

## **How to Choose the Right Back Box?**

When choosing the right back box, consider the number of gangs needed for your installation. A single socket back box is designed for a single electrical socket, while multi-gang boxes are available for multiple sockets. Ensure the back box is deep enough to accommodate the wiring and any additional components, such as [electric plugs](https://hken.rs-online.com/web/c/connectors/mains-dc-power-connectors/plug-sockets/), [electronic switches](https://hken.rs-online.com/web/c/switches/) or dimmers. Also, factor in the mounting options and material choice (metal or plastic) based on the installation environment and durability requirements.

## **How to Install a Socket Box?**

To install a socket box, start by selecting the appropriate location and marking the area where the box will be placed. Use a drill to create holes for fixing clips or mounting screws. Then, secure the back box to the wall, ensuring it is level and properly aligned. After fitting the box, wire the [industrial plug](https://hken.rs-online.com/web/c/connectors/mains-dc-power-connectors/industrial-power-connectors/) or socket according to electrical standards. If you're unsure or lack experience, it's advisable to hire a professional to ensure [industrial workplace safety](https://hken.rs-online.com/web/content/discovery/ideas-and-advice/workplace-on-site-safety-guide) and compliance with local regulations.
