Manufacture of wiring devices
What this code covers
Use this class for manufacture of wiring devices when the main activity includes Manufacture of bus bars, electrical conductors (except switchgear-type) and Manufacture of ground fault circuit interrupters (GFCIs). Check exclusions and nearby codes before applying it to a mixed activity.
Official NACE Rev. 2.1 labels and explanatory notes are imported from the source dataset. Plain-language explanations are shown separately so readers can compare interpretation with the source text.
No child codes; this is a class-level code.
- This class includes the manufacture of current-carrying and non-current-carrying wiring devices for electrical circuits regardless of material.
- manufacture of bus bars, electrical conductors (except switchgear-type)
- manufacture of ground fault circuit interrupters (GFCIs)
- manufacture of lamp-holders
- manufacture of ceramic insulators, see 23.43
- Compare with 23.43, 27.31, 27.32 when the main activity overlaps another code.
- Check national equivalent caveats before using this code for local registration or filing workflows.
- If the main revenue activity appears in an exclusion, compare the alternative code before deciding.

Rev. 2 code 27.33 maps to the same Rev. 2.1 class 27.33 Manufacture of wiring devices.
Official close match imported from NACE Rev. 2.1.
Low operational impact is expected, but systems should still store the target Rev. 2.1 version explicitly.
Confirm the target version field and update references where Rev. 2.1 is required.
