Question:
The NEC addresses the 25 foot tap rule for transformer connections in Section 240.21(C ). Does this rule allow 25 feet of conduit from enclosure to enclosure, or is the length of the wire limited to not more than 25 feet?

A
Answer:
Hi Peter,
The tap rules in Section 240.21 apply to the length of tap conductors, not the length of the raceway enclosing the conductors.
Hope this is helpful.
