Yes, it is possible to fit a USB wall outlet in a metal electrical box. However, some considerations need to be taken into account to ensure proper installation.
1. Box Size:
The first thing to consider is the size of the metal electrical box. USB wall outlets tend to be larger than standard electrical outlets due to the additional space required for the USB ports. Therefore, it is essential to ensure that the metal box is spacious enough to accommodate the larger size of the USB wall outlet.
2. Wiring Capacity:
Another crucial consideration is the capacity of the metal electrical box to hold the necessary wiring. When installing a USB wall outlet, additional wiring may be required to support the USB ports. Therefore, check the rating and specifications of the metal box to ensure it can handle the increased load and wiring requirements.
3. Grounding:
Proper grounding is essential for electrical safety. Ensure that the metal electrical box is properly grounded to prevent any potential electrical hazards. This typically involves connecting the metal box to the grounding wires in the electrical system.
4. Compatibility:
Verify if the specific USB wall outlet you intend to install is compatible with metal electrical boxes. Most manufacturers provide information regarding compatibility in the product specifications or installation guidelines. Ensure that the USB wall outlet you choose explicitly states it can be installed in a metal electrical box.
Installation Process:
To install a USB wall outlet in a metal electrical box, follow these general steps:
- Turn off the power: Before beginning any electrical work, switch off the power supply to the circuit you will be working on by flipping the corresponding circuit breaker.
- Remove the cover plate: Unscrew and remove the cover plate from the existing electrical outlet.
- Disconnect wires: Carefully disconnect the wires from the existing outlet. Take note of the connections to ensure proper reconnection.
- Connect the USB wall outlet: Follow the manufacturer’s instructions to connect the wires to the USB wall outlet. Pay attention to the specific wiring color codes and connections.
- Place the USB wall outlet into the metal electrical box: Gently insert the USB wall outlet into the metal box, ensuring it fits securely.
- Attach the cover plate: Attach the cover plate to the USB wall outlet, securing it in place using provided screws.
- Turn on the power: After installing the USB wall outlet, switch the power supply back on. Test the outlets and USB ports to ensure they are functioning correctly.
USB wall outlets provide a convenient and efficient way to charge electronic devices directly. While it is entirely possible to fit a USB wall outlet in a metal electrical box, it is essential to consider factors such as box size, wiring capacity, grounding, and compatibility. By following the proper installation process and considering these factors, you can safely and successfully install a USB wall outlet in a metal electrical box.
