Class Code 3179: Electrical Apparatus Manufacturing NOC — Workers' Comp Insurance
Covers manufacturers producing electrical apparatus and components, such as switches, panels, and electrical devices, when no more specific electrical manufacturing classification applies. It reflects assembly-line and bench-based production work involving electrical components.
- Risk level:
- moderate
What code 3179 covers
Class 3179 applies to manufacturers producing electrical apparatus and components not falling under a more specific NCCI classification, covering assembly, wiring, and testing of electrical devices, panels, switches, and similar products. The work is generally assembly- and bench-based, involving hand tools, small power tools, and testing equipment rather than heavy machining, though production volume and line-based work add repetitive-motion considerations. This is an NOC classification; certain specific electrical products, such as television/radio/telecommunication devices, have their own dedicated manufacturing classification and would be evaluated under that more specific code instead. Manufacturers who also perform on-site installation of the equipment they produce may need that field-installation work evaluated under a different, contractor-focused classification.
Included operations
- Assembly of electrical panels, switches, and apparatus
- Wiring and electrical component assembly
- Testing and quality control of electrical products
- Packaging and shipping of finished electrical apparatus
Businesses that typically carry 3179
- Electrical panel and switchgear manufacturers
- Electrical component and device manufacturers
- Electrical apparatus assembly plants
- Small and mid-size production shops
- Contract manufacturers serving other businesses
- Regional production and distribution facilities
Common misclassifications
Code 3681
Electrical apparatus manufacturers and electronics/telecommunication device manufacturers can be confused, though more specific product types have their own dedicated classification.
Code 3632
Electrical apparatus manufacturers doing their own metal enclosure fabrication can blend general machine shop work into what should remain the electrical apparatus classification.

State differences
This entry uses standard NCCI class code phraseology, which applies in most NCCI-governed states. Pennsylvania (PCRB), Delaware (DCRB), California (WCIRB), New Jersey (NJCRIB), Michigan, New York (NYCIRB), and Massachusetts maintain their own classification manuals, and code numbers or phraseology can differ there. Our agency confirms the correct classification for your state before quoting.

Class code 3179 questions
Does this code cover assembling electrical panels and switches?
Yes, that's a typical fit for this classification, covering assembly, wiring, and testing of electrical apparatus.
What if we manufacture a more specific product, like telecommunication devices?
A more specific NCCI classification would typically apply instead, such as the code for television, radio, or telecommunication device manufacturing.
Does this cover installing the equipment we manufacture?
No, on-site installation by field technicians or electrical contractors is evaluated under a separate classification.
Is this a heavily machinery-based classification?
It's generally assembly- and bench-based rather than heavy machining, though production volume and repetitive tasks are still underwriting considerations.
