What NEC table provides conduit fill requirements for IMC conduit?

• A. C.1
• B. C.4
• C. C.5
• D. C.8

Answer: (B)

Conduit fill is about how much space inside a raceway can be occupied by the conductors, so the code provides a table that relates the size of the IMC conduit to how many conductors of various sizes can be placed inside it. For IMC, the relevant data are in Table C.4. This table shows, for each IMC size, the maximum number of conductors (and the corresponding fill) allowed, ensuring there’s enough room for installation and pulling without crowding. The other tables in the same section cover different raceways or conditions, so they don’t provide the IMC-specific fill values.
