What is the requirement for terminating metal raceways?

The requirement for terminating metal raceways emphasizes the need for safety and proper electrical performance. Termination to a listed non-metallic fitting or spacer is appropriate under certain conditions. This allows for flexibility in installation while still ensuring that the raceway maintains its intended protective and conductive properties.

Using non-metallic fittings can be beneficial in environments where corrosion is a concern or where grounding issues might arise. However, it is important that these non-metallic options are listed and rated for use with metal raceways to ensure compliance with electrical codes.

The ability to use a listed non-metallic fitting indicates that there are scenarios where metal fittings are not required, allowing for variances in the types of materials used while still conforming to safety regulations. This choice provides options for electricians to choose the most suitable materials based on the specific application and environment they are working in.

Other considerations, such as electrical continuity and connection to metal fittings, while important in general electrical practice, do not encompass the flexibility provided by the correct use of listed non-metallic fittings. Additionally, the limitation on raceway length pertains to installation practices rather than termination requirements specifically. Therefore, focusing on the listing and suitability of the installed components is key in this context.
