Can non-metallic boxes be used with metallic devices?

Non-metallic boxes can indeed be used with metallic devices, provided that the installation is completed properly to ensure security and safety. This includes making sure that the connections between the non-metallic box and the metallic devices are solid and compliant with relevant codes.

The ability to mix non-metallic boxes with metallic devices takes advantage of the insulation properties of non-metallic materials while accommodating a wide range of device types. As long as the electrical connections are made secure, the use of a non-metallic box does not create an unsafe condition when interfaced with metallic devices. Compliance with the National Electrical Code ensures proper installation methods are followed, maintaining the integrity of the electrical system regardless of the materials used in the boxes and devices.

This flexibility is particularly useful in various applications where metallic devices might be preferred for their durability or other characteristics, without needing to resort to metallic boxes which might be less suitable for certain environments or applications.
