Within Article 310, what is the minimum size for stranded conductors installed in raceways?

The minimum size for stranded conductors installed in raceways, as outlined in Article 310 of the National Electrical Code (NEC), is 8 AWG or larger. This specification is important for ensuring that the conductors can handle the expected loads and remain safe during operation.

Stranded conductors are typically chosen for flexibility and ease of installation in various applications, particularly in raceways where movement and bending may be required. The requirement for a minimum size helps to prevent overheating and potential electrical failures, ensuring that the conductors can carry current without excessive resistance, which could lead to increased heat generation.

This minimum size of 8 AWG takes into account the conductivity of the material used, the potential for current load, and safety considerations for both the electrical system and any personnel working near the installation. Ensuring that conductors meet or exceed this minimum size requirement helps maintain the overall integrity and safety of the electrical installation.
