Question on Mechanical and Electrical Continuity of Conductors (Section 300.13 A)

[Citrus Bergamia]

Hello guys.

Section 300.13 (A) indicates that "Conductors in raceways shall be continuous between outlets, boxes, devices, and so forth. There shall be no splice or tap within a raceway unless permitted by [list of sections]."

I want to splice the conductors of a feeder circuit that runs underground thru non-metallic PVC SCH 80 pipes. This feeder connects the service disconnecting means to a panelboard. I believe NEC section 300.13 implies that conductors (feeder or branch) can be spliced inside boxes that remain accessible, such as handhole enclosures, but personally I've never seen a spliced feeder circuit, so I'm not sure if that is allowed as per NEC.

Can anyone help me understand this better? Thanks in advance.

Yes feeder conductors are permitted to be spliced.

Section 300.13 (A) indicates that "Conductors in raceways shall be continuous between outlets, boxes, devices, and so forth. There shall be no splice or tap within a raceway unless permitted by [list of sections]."

In other words, if you have a need to splice your conductors, the splice needs to occur in a location you can access it. Such as a junction box, conduit body, or handhole. You aren't permitted to splice it externally, and then pull the splice connector deep within the run of the raceway with the conductors. The reason is that if there is any need to inspect or maintain on the splice, it needs to be possible to access it.

It is rare for the NEC to prohibit splices altogether on any given type of circuit. The only example I know about that explicitly prohibits splices is the 100 ft tap rule in 240.21(B).
