Metal junction boxes and plastic junction boxes both have their own advantages and are suitable for different applications. But there are differences between metal junction boxes and plastic junction boxes. The following is explained by the plastic junction box manufacturer.
Lightweight: Plastic junction boxes are lightweight and easier to handle and install compared to metal junction boxes.
Corrosion resistance: Plastic junction boxes are resistant to corrosion, making them suitable for outdoor or damp environments.
Insulation: Plastic junction boxes provide better insulation and are non-conductive, making them suitable for certain electrical applications.
Cost: Plastic junction boxes are generally more affordable than metal junction boxes.
The choice between metal and plastic junction boxes depends on the specific requirements of the installation, including environmental conditions, electrical needs, and budget considerations.
Durability: Metal junction boxes are more durable and long-lasting compared to plastic junction boxes. They are resistant to impact and can provide better protection in harsh environments.
Fire resistance: Metal junction boxes are more fire-resistant than plastic junction boxes, making them suitable for installations in areas where fire safety is a concern.
Grounding: Metal junction boxes provide grounding capabilities, which can be important for electrical safety.
Cost: Metal junction boxes are generally more expensive than plastic junction boxes.
The difference between metal junction boxes and plastic junction boxes lies in durability strength, fire resistance, materials, insulation, corrosion resistance, cost, etc. Both have their own advantages and are suitable for different applications.
Metal junction boxes are made of steel or aluminum and are more durable and fire-resistant compared to plastic junction boxes. They are also more suitable for outdoor or high-temperature applications. However, they are heavier and more expensive than plastic junction boxes.
Plastic junction boxes are made of PVC or other types of plastic and are lightweight, cost-effective, and easy to install. They are suitable for indoor applications and are non-conductive, making them safer for use in electrical installations. However, they are not as durable or fire-resistant as metal junction boxes.
