NEC tap rules
(OP)
Does anyone know the engineering/technical reasons for, or historical evolution of, the NEC 10ft, 25ft, and unlimited outdoor tap rule as applied to branch circuits, and the tranformer tap rule for 10ft commercial and 25ft industrial. i.e why the specific differences in tap conductor length?
Thanks
Thanks

The longer distances are allowed in applications which have more limiting requirements in overcurrent protection and accessibility.
