Class Code: 3179

Per NCCI's Scopes Code Description:

Applies to the manufacture of electrical apparatus, hardware or wiring devices that are not otherwise classified in the Basic Manual. Operations such as machining, drilling, tapping, grinding, threading, stamping, finishing, assembling, inspection, packing and shipping are included in this classification.

While the term “electrical apparatus” implies a broad spectrum of devices powered by electricity, the manufacture of apparatus included in this classification is of the nature of those items described below.

Code 3179 includes the manufacture of electrical apparatus such as electrical cable connectors, conductors, snap-in fittings, cable straps, cable supports, bushings, wall switches, couplings, nipples, fixture extensions and clamps. This classification also includes the manufacture of fractional horse power motors, flashlights, fire alarm sirens, smoke alarms, thermostats, grocery check-out laser scanners, and electrical appliances such as microwave ovens, toasters, irons, percolators, electric shavers, waffle irons, electric grills, hot plates, fans, humidifiers and vacuum cleaners.

Manufacturers of metal household or commercial refrigerators who produce or assemble refrigeration units are assigned to Code 3179 while all other operations related to metal refrigerator manufacturing are assigned to Code 3076. The use of both codes is permitted when manual rules pertaining to division of a single employee’s payroll and physical separation of operations are met.

By analogy, the manufacture of cryogenic devices, evaporative coolers, and household or commercial tanning beds is afforded a similar classification treatment as stated in the preceding paragraph. Code 3179 applies to the assembly of the electronic parts for the tanning beds and Code 3076 applies to the manufacture of the metal unit that houses the electronic parts.

Code 3724 includes installation or repair of truck trailer refrigeration systems when this work is performed away from the premises of the repairer or installer. Assign Code 3179 to these operations when the installation or repair work is performed at the insured’s shop. This distinction is made since Code 3724 includes the “not otherwise classified” installation or repair of equipment at a customer’s premises while Code 3179 includes refrigeration work at the installer or repairer’s shop.

Code 3179 is a “not otherwise classified” (NOC) classification. This means that Code 3179 applies to an employer’s operation(s) only when no other classification more specifically describes the employer’s operation(s). The following is a representative list of operations somewhat related in nature to Code 3179 operations that are not assigned to Code 3179.

3648 Automotive Lighting, Ignition or Starting Apparatus Mfg. NOC

3642 Battery Mfg.—Dry

3647 Battery Mfg.—Storage

3574 Computing, Recording or Office Machine Mfg. NOC

4110 Electric Bulb Mfg.

3643 Electric Power or Transmission Equipment Mfg.

3685 Instrument Mfg. NOC

3681 Television, Radio, Telephone or Telecommunication Device Mfg. NOC

In addition to this representative list, one should review sources such as the alphabetical index in this manual to determine whether a classification other than Code 3179 or a classification other than a classification on the above list is applicable to the operation(s) being reviewed for classification purposes.
