Class Code 7601
Aerial Line Construction
Class Code 7601 covers aerial line construction in California — work on overhead electric and communication lines including pole setting, conductor stringing, splicing, and live-line operations. The September 1, 2026 approved pure premium rate for this classification is $3.660 per $100 of payroll. For employers who deploy linemen, groundmen, and storm-restoration crews, accurate classification and targeted safety programs directly affect workers' comp costs.
What Class Code 7601 Covers
This classification applies to crews that construct, install, maintain, test and repair overhead electrical and aerial communication lines and related pole-top equipment. Typical operations include setting and removing poles, digging and backfilling pole holes, operating digger derricks and bucket trucks, stringing and tensioning conductors, splicing and terminating aerial cables, installing transformers and crossarms, and performing live-line (hot) work when authorized and properly equipped. It covers both scheduled construction and emergency storm-restoration activities performed along roadways and rights-of-way. Work performed exclusively inside buildings, underground distribution work, or low-voltage interior wiring is normally classified differently and should not be placed in 7601.
Who It Applies To
- Electric utility line crews and municipal utility departments
- Specialty overhead line contractors (powerline contractors)
- Telecommunications contractors performing aerial cable on poles
- Storm-restoration crews and emergency outage contractors
- Contractors operating digger derricks, bucket trucks, and pole-setting crews
Common Job Duties
- Climbing wooden or composite poles and working at pole-top elevations
- Operating bucket trucks, digger derricks, cranes, and line-moving equipment
- Stringing, tensioning, and sagging overhead conductors and fiber optic cables
- Splicing, terminating, and installing transformers, insulators, and crossarms
- Installing temporary grounding, phasing and testing circuits
- Performing switching, live-line work with hot sticks or insulated tools, and restoration

Understanding the $3.660 Rate
The approved pure premium rate of $3.660 per $100 of payroll represents the estimated cost of future workers' compensation claims for this class per unit of payroll and is the starting point insurers use to price coverage. The final premium an employer pays also includes insurer expense and profit loadings, policy deductibles or retentions, experience modification (EMR), classification audits, and any credits or debits for loss control and claims history. Accurate payroll reporting, proper classification, and an active safety and return-to-work program can materially reduce the ultimate premium.
Cal/OSHA Compliance Requirements
Aerial line construction must comply with Cal/OSHA Electrical Safety Orders and Construction Safety Orders covering qualified electrical worker training, minimum approach distances, grounding and bonding, and lockout/tagout for de-energized work. Employers must follow Cal/OSHA rules for aerial lifts and fall protection, perform regular equipment inspections (bucket trucks, derricks, harnesses), provide appropriate PPE and hot-line tools, and maintain written rescue and emergency response plans for pole-top and bucket rescues. Regular documented training, competency verification, and supervisory oversight are required for employees performing live-line operations.
How Key HR Helps Employers Under Class Code 7601
A PEO like Key HR can centralize workers' comp coverage, ensure accurate employee classification for 7601, and administer payroll reporting and audits to prevent misclassification exposure. Key HR provides targeted loss control services—pole-top rescue, fall protection and aerial lift training, hot-line safety, equipment inspection programs—and hands-on claims management and return-to-work coordination to reduce claim duration and help lower an employer's experience modification over time.

How is Class Code 7601 different from codes for inside wiring or underground work?
7601 specifically covers overhead aerial line construction and related pole-top operations, including live-line techniques and pole setting. Inside wiring, low-voltage building electrical work, and underground distribution have separate WCIRB classifications and lower exposure profiles, so they should be reported under the appropriate codes to avoid overpaying.
What training and qualifications should employers provide for workers in this class?
Employers must provide qualified electrical worker training, aerial lift and bucket-truck training, fall protection and suspension trauma awareness, pole-top rescue, grounding and bonding procedures, and documented competency checks. Training should be repeated per Cal/OSHA schedules and after incidents or equipment changes.
What practical steps reduce workers' comp costs for aerial line crews?
Maintain accurate payroll and classification records, implement a formal safety program with routine site inspections, use documented pre-job briefings and rescue plans, invest in training and PPE, enforce drug and fatigue policies for storm work, and work with your PEO or carrier on proactive claims management and transitional duty to shorten claim duration.
