What class codes apply to fiber construction workers?

Fiber construction workers are classified under several NCCI codes depending on their specific duties. Common codes include: 7600 (Telephone or Telegraph Line Construction) for aerial fiber work on poles, 6325 (Conduit Construction) for underground duct and conduit installation, 5190 (Electrical Wiring) which may apply to fiber splicing and termination in some states, and 5022 (Masonry) which occasionally applies to underground vault construction. The specific code depends on the state and the primary nature of the work. Aerial fiber workers on poles may be classified under 7600 with rates significantly lower than tower climbing codes (3724 or 7601) because the heights are typically 20-40 feet rather than hundreds of feet. Underground fiber workers under codes like 6325 have the lowest rates among fiber classifications since there is no height exposure, though the work involves heavy equipment and excavation risks. For companies performing multiple types of fiber work (aerial, underground, splicing), payroll should be split between applicable codes based on each employee's actual duties. A splicer who works exclusively in ground-level or vault environments should not be rated at the aerial construction code. Proper classification at policy inception prevents audit surprises.
