I am looking for clarification regarding not requiring overcurrent protection on Service Conductors.
If we look at section 230.1 figure we see that the "service entrance conductors" refer to section 4.
If we go to section 4 of 230 there is no mention of overcurrent protection for Service Conductors.
If we look at 240.21 we are told that overcurrent protection should be provided in each ungrounded conductor where they receive their supply with the exception of 240.21(A)-(H)
If we look at 240.21 A-H we see A.Branch circuit conductors B.feeder taps C.transformer secondary conductor D. Service Conductors E. Busway Taps F. motor Taps G. Conductor from Generator or H. Battery
It looks like 240.21 (D) would completely relate to overcurrent protection for Service Conductors. 240.21(D) tells us to look at 230.91 which relates to location.
My question, what article would mostly relate to having service entrance conductors (such as SEU) strapped to a house with no overcurrent protection until it terminates in to a disconnect? Would that be "outside taps of unlimited length?" or "transformer secondary conductors?" because it surely doesnt seem to be 240.21(D)
