Correct answer to question 3032
- C: There is no length limit
Explanation
Outside taps of unlimited length are allowed if they are protected from physical damage, terminate at a single breaker or set of fuses that limits the load to their ampacity, and the OCPD is part of or adjacent to the disconnect. See 240.21(B)(5).
