Overhead power and line construction is one of the highest-rated workers compensation classes in the entire construction industry. In 2026, a power-line contractor typically pays $10 to $28 per $100 of payroll on class code 7600 — before any experience-modification credit or debit. A line crew running $1.5M in field payroll can see $150,000 to $400,000 in workers comp premium alone. That is not a typo, and it is why getting the class-code split and the ex-mod right is worth more to a line contractor than to almost any other trade.
The rate is a direct reflection of severity. Linemen work at height, often on or immediately adjacent to energized conductors carrying thousands of volts. When something goes wrong — an arc flash, a fall from a pole or bucket, a struck-by from a dropped conductor or a digger derrick — the claim is rarely minor. It is a hospitalization, a permanent disability, or a fatality. Carriers price code 7600 for that tail, and many standard admitted carriers simply will not write it at all. The result is a class that lives largely in the specialty-program and excess-and-surplus world, where the right agency relationships determine whether you get quoted at all.
Your premium is driven almost entirely by how payroll is distributed across codes. The single most common and most expensive mistake in this trade is letting an auditor sweep groundmen, flaggers, and office staff into 7600 because payroll records did not clearly separate them.
| Class code | Scope | Typical 2026 rate (per $100 payroll) |
|---|---|---|
| 7600 | Electric light or power line construction — overhead | $10.00–$28.00 |
| 5040 | Iron/steel erection — poles, towers, structures | $9.00–$22.00 |
| 6325 | Conduit construction for cables/wires (underground) | $6.00–$12.00 |
| 5190 | Electrical wiring & inside/low-voltage work | $3.00–$6.50 |
| 8742 / 8810 | Outside sales & clerical (split out where legitimate) | $0.20–$0.90 |
Rates vary by state, carrier, and your experience modification factor. Georgia, Florida, and the Carolinas each publish different loss costs. In a class rated this high, the compounding effect of a clean ex-mod is dramatic: moving from a 1.25 modifier to a 0.90 on $1.5M of 7600 payroll can swing the premium by six figures.
This is your largest single cost and the coverage most likely to be scrutinized at audit. Statutory limits are mandatory, and utility primes will require a waiver of subrogation. Employer's liability limits are usually pushed to $1M/$1M/$1M.
Confirm the policy does not carry a crippling "damage to property" or "your work" exclusion that would gut coverage on a live utility corridor. Contact with energized lines, tree and vegetation contact, and property damage during pole setting are the recurring GL claims.
Bucket trucks, digger derricks, pole trailers, and material handlers drive a heavy auto schedule, and FMCSA rules apply once you cross weight and interstate thresholds. Inland marine (contractors equipment) covers the derricks, pullers, tensioners, and tooling a standard property policy will not.
Transformer and equipment oil, herbicide and vegetation-management chemicals, and fuel spills are pollution claims, not GL claims. Utility contracts increasingly require CPL on the schedule.
Transmission and distribution primes routinely require $5M to $25M in excess limits. Pricing is highly sensitive to your safety program, driver MVRs, and loss history because the underlying exposure is catastrophic.
Before you can energize a single span for a co-op, municipal utility, or investor-owned utility, your certificate has to clear their insurance schedule. The recurring 2026 requirements:
Bettr Coverage is the Southeast's independent agency for infrastructure construction — power, fiber, water, civil, solar, tower. We shop the specialty and excess markets that write code 7600 side-by-side and fight your ex-mod line by line.
Get a free infrastructure reviewThe primary code is 7600 (electric light or power line construction). Underground conduit falls under 6325, inside wiring under 5190, and pole/tower setting can pull 5040 depending on the state. Groundmen and clerical should be split into their correct lower codes.
Linemen work at height on or near energized conductors, so a single claim can be catastrophic or fatal. Electrocution, falls, and struck-by incidents produce severe, high-dollar losses, and carriers price code 7600 defensively — many will not write it at all.
Yes — general liability, commercial auto for bucket trucks and digger derricks, inland marine on equipment, contractors pollution liability for transformer oil and herbicide, and a $5M-$25M umbrella. Utility contracts require additional insured and waiver of subrogation.
Keep your ex-mod below 1.0, split class codes correctly at audit so groundmen and clerical are not swept into 7600, and document a compliant safety and return-to-work program. Each lever moves real money in a class rated this high.
It should, but confirm the schedule and check whether FMCSA filing thresholds apply for interstate hauling. Mounted equipment on the truck is usually covered by inland marine, not the auto property section.
Yes. Utility and transmission projects frequently need bid, performance, and payment bonds. Our sister brand BettrBonds writes contract surety on Southeast infrastructure projects, coordinated with your insurance program.
