Tap Conductor Conditions

Correct Answer

D — All of the above.

Concept and Reasoning

The 25-ft tap rule permits omission of overcurrent protection at the tap point only when all prescribed conditions are met, including conductor ampacity, physical protection, length limitation and termination in a suitable overcurrent device/equipment. The complete condition set is represented by option D.

Calculation / Key Relation

Tap length ≤25 ft and all code conditions must be satisfied

Exam Takeaway

Tap rules are exceptions: every listed safety condition matters.

Common Mistake

Do not treat the 25-ft length by itself as sufficient compliance.
