| NSI | N-350* | max-size naming; verify range |
Cross-references identify copper-alloy split bolts of equivalent published range; dual-rated Cu/Al bodies (KSU, SK, HPS) are a different class. *Pattern-matched; confirm on datasheet.
Where it's used
- 350 kcmil feeder taps and splices in gutters, wireways, and pull boxes
- Parallel-run bonding and ground bus connections in switchgear rooms
- Utility, transit, and industrial service taps where a compression tool is impractical
How to install
Strip, wire-brush bright, seat the run in the bolt saddle with the tap alongside, hand-run the nut, torque to the marked value, then insulate to the conductor's rating per NEC 110.14(B) (rubber tape + vinyl, or a snap-on split bolt cover). Not permitted for buried or encased grounding electrode conductor splices (NEC 250.64(C)) — use irreversible compression there.
