Which NEC section covers Feeder Taps?

• A. NEC Section 240.4: Protection of conductors
• B. NEC Section 240.21(B): Feeder Taps
• C. NEC Section 240.21(C): Transformer secondary conductors
• D. NEC Section 230.6: Conductors outside the building

Answer: (B)

Feeder taps are addressed specifically in NEC 240.21(B). This section lays out the rules for conductors tapped from a feeder to supply a branch circuit or transformer, including how those tapping conductors are sized and protected and the permissible tap lengths when the tap is taken from a feeder ahead of the overcurrent device. It’s the exact place in the code that governs the practice of creating a feeder tap and ensures proper coordination between protection and conductor sizing so the tapping conductors don’t create unsafe conditions. The other sections mentioned cover different topics: 240.4 deals with protection of conductors in general, not the special case of taps; 240.21(C) covers transformer secondary conductors (not feeder taps); and 230.6 addresses conductors outside the building.
