Linemen build and maintain the electrical grid — the transmission and distribution systems that carry power from generation to the customer.
It is a separate trade from inside electrical work, with its own apprenticeship, its own employers, and its own hazards.
It is also one of the more dangerous occupations in the country, and any honest account of it has to say so.
What line workers actually do
Line work is the grid itself: installing and repairing the high-voltage cables and equipment that make up transmission and distribution systems, both overhead and underground.
The voltages involved run up to hundreds of thousands of volts.
The tasks span a wider physical range than most people expect.
Erecting poles and light or heavy transmission towers at one end; replacing a fuse or an entire transformer at the other.
Stringing and splicing conductor, setting and connecting equipment, and locating and repairing faults in systems that run for miles.
Two things follow from that.
First, the work is outdoors in all weather — and specifically because of weather, since storms and other natural disasters damage lines and the job is to restore them.
Second, it is mobile: line workers drive utility vehicles as a matter of course, and crews working on interstate grids may travel long distances.
The other defining physical requirement is height.
You must be comfortable working at considerable height and in confined spaces, able to climb poles and towers, and able to balance while working on them.
That is not a preference; it is an entry condition.
Why this is a separate trade, not a specialisation
This distinction matters enough that the whole site is organised around it, so it is worth setting out the evidence in one place.
Different occupation.
Line workers are classified as Electrical Power-Line Installers and Repairers, SOC 49-9051 — a different occupation from Electricians, SOC 47-2111, with separate federal wage and injury statistics.
Different apprenticeship.
Per the electrical training alliance, the outside lineman programme runs around three and a half years against five for inside wireman.
They are separate programmes with separate selection, not tracks within one.
Different employers.
Utilities, rural electric co-operatives, and line contractors — not the electrical contractors who employ inside electricians.
Different work and hazards.
Grid infrastructure at transmission and distribution voltages, outdoors, at height, in weather.
The practical implication for anyone choosing: the electrician licence ladder does not apply here.
Apprentice, journeyman, and master are inside-wireman structure.
Line work has its own progression, and assuming the two are interchangeable is the single most common error people make about this trade — see inside wireman vs lineman.
The hazard, stated plainly
This trade is genuinely dangerous, and the numbers are not ambiguous.
Electrical power-line installers and repairers appeared among the ten civilian occupations with the highest fatal work injury rates in every year from 2011 to 2015, at rates between 19.2 and 23.9 per 100,000 full-time equivalent workers.
Exposure to electricity is the leading cause of fatal injury in the occupation — nearly half of the fatalities in that period, 62 of 131.
For comparison, exposure to electricity accounted for roughly 3 percent of fatal injuries across all occupations.
Falls to a lower level accounted for about a fifth of line-worker fatalities, and transportation incidents for over a quarter.
Among non-fatal cases, overexertion and bodily reaction leads, with falls high on that list too.
Those figures explain a great deal about the trade that would otherwise seem excessive: the length of the apprenticeship, the formality of the procedures, the emphasis on crew discipline, and the culture around not cutting corners.
They are also why the work is compensated the way it is.
This page states that once and then moves on, which is the right way to handle it.
People do this work for full careers and retire from it.
But anyone deciding whether to enter the trade deserves the number rather than an impression.
One note on the figures
Energised work and the crew
Two features of the working method shape the trade more than the equipment does.
The first is that a great deal of line work happens on systems that cannot simply be switched off.
Taking a circuit out of service means taking customers off supply, so techniques exist for working on energised conductors — insulated tools and equipment, insulated aerial devices, and in some cases specialised methods for working directly on lines at transmission voltages.
Whether a given job is done energised or de-energised is a deliberate decision made in advance, not an improvisation.
The consequence is that procedure carries more weight here than almost anywhere else in the trades.
Knowing what is energised, what has been isolated, what has been grounded, and who verified each is not administrative diligence — it is the mechanism keeping people alive.
The formality that inside electricians sometimes find heavy in industrial work is lighter than what is normal on a line crew.
The second feature is that this is genuinely crew work.
Line jobs are performed by teams with defined roles, and the safety of each person depends on the others doing what was agreed.
That produces the trade's characteristic culture — direct communication, low tolerance for improvisation, and a strong preference for people who do exactly what they said they would.
It also means that fitting into a crew is part of being employable, in a way that is less true of a residential electrician working alone out of a van.
Who employs line workers
Three broad kinds of employer, and the differences between them are real.
Investor-owned utilities employ line workers directly to build and maintain their own systems.
This tends to mean a defined service territory, structured progression, and the employment characteristics of a large regulated company.
Rural electric co-operatives serve member-owned systems, often across large, sparsely populated territories.
Smaller organisations, wider individual responsibility, and long drives.
Line contractors build and maintain systems under contract to utilities.
This is the most mobile route — crews follow the work, travel is expected, and storm response is a significant part of the business.
There is also a distinction between working the same system for years and moving between them.
A utility lineman comes to know a specific grid; a contractor lineman sees many.
Both are legitimate careers and they suit different people.
Storms are part of the job description
When the weather is at its worst, this trade goes to work.
That is not incidental to line work — it is one of its defining features.
Storm restoration means being called out at short notice, travelling to affected areas that may be far from home, and working extended hours in conditions that caused the damage in the first place.
Mutual aid arrangements between utilities mean crews routinely cross state lines to help restore systems after major events.
It is demanding in a way that is easy to underestimate from the outside: long shifts, poor conditions, disrupted sleep, and time away from family at no notice.
It is also, for many line workers, the part of the job they are proudest of, and the trade's culture reflects that.
Financially it matters too, because storm and travel work drive a large share of total earnings in this trade — which means a base hourly rate substantially understates what the work pays.
That structure is covered in storm work, travel, and how line pay is structured.
How you get in
Through a line apprenticeship, which is a separate programme from the inside-wireman apprenticeship and typically shorter — around three and a half years for outside lineman per the electrical training alliance.
The entry conditions differ too.
Alongside the usual documentary requirements, the physical demands are screened for directly: climbing, working at height, and sustained physical work outdoors.
Programmes commonly include climbing instruction early, and it is a genuine filter rather than a formality.
What transfers from inside electrical experience is less than people assume.
The theory overlaps, the working environment and the techniques largely do not, and holding an electrician licence does not shorten a line apprenticeship.
What the line apprenticeship involves, and specifically how it differs, is covered in the line apprenticeship.
The general mechanics of registered apprenticeship — how wage progression works, why registration status matters, how eligibility lists operate — are the same as for any trade and are covered in how to become an electrician.
The line-specific page covers only what is different.
Where a line career goes
Progression runs from apprentice through to journeyman lineman, then toward crew leadership — foreman and general foreman — and from there into supervision, planning, or training roles within a utility or contractor.
Two specialisations are worth knowing about.
Transmission versus distribution is the main internal split, and the two involve different structures, voltages, travel patterns, and crew types — see transmission vs distribution.
Underground work is its own discipline, with different equipment and different hazards from overhead.
Some line workers also move into substation work, which sits adjacent to the trade and involves the equipment at the ends of the lines rather than the lines themselves.
