Direct Answer
Both are IBEW trades, but they are different careers. An inside wireman wires buildings — conduit, panels, lighting, controls — through a 5-year local IBEW-NECA apprenticeship. An outside lineman builds and maintains the power grid itself — poles, towers, substations — through a ~3.5-year line constructor apprenticeship, with heavy travel, storm work, and generally higher pay to match the harder life.
Inside Wireman vs Outside Lineman
I’m an inside wireman — 13 years in IBEW Local 134, Chicago. I’ve worked alongside linemen, lost apprenticeship classmates to the outside, and fielded this question from applicants more times than I can count. Here’s the honest comparison, without trash-talking either side.
What an Inside Wireman Does
Inside wiremen build the electrical systems inside commercial, industrial, and residential buildings: bending and running conduit, pulling wire, setting panels and switchgear, installing lighting, fire alarm, and building controls. It’s my trade, and the variety is real — one year you’re on a high-rise, the next you’re in a data center or a hospital.
The path in is a 5-year apprenticeship through your local IBEW-NECA JATC, using the electrical training ALLIANCE curriculum. Entry runs through an aptitude test scored on a 1–9 scale — most locals require a 4 or higher — followed by a ranked interview. I break the whole process down on the apprenticeship requirements page.
What an Outside Lineman Does
Outside linemen build and maintain the transmission and distribution system — the poles, towers, lines, and substations that move power from the plant to the building I wire. When a storm knocks out a region’s grid, linemen are the ones rolling in from three states away to restore it. It is high, heavy, outdoor work in every kind of weather, and the people who do it are proud of that for good reason.
Outside apprenticeships are not run by your local JATC. They’re run by regional line constructor JATCs — outfits like ALBAT (American Line Builders Apprenticeship Training), Northwest Line JATC, Southeastern Line Constructors, and the California-Nevada JATC — and typically run about 3.5 years / ~7,000 hours. Expect to obtain a Class A CDL during the apprenticeship, and know that climbing school matters: if you can’t get comfortable on wood at height, this isn’t your trade.
The Money Question
In the same region, outside linemen generally out-earn inside wiremen, and travel work usually adds per diems on top. The federal data backs the pattern: the Bureau of Labor Statistics reports a $62,350 median annual wage for electricians broadly (May 2024), while tracking line installers and repairers as a separate, higher-paying occupation. Union scale in strong locals runs well above those medians on both sides — see actual local-by-local rates on the IBEW pay scales page. The lineman premium isn’t free money, though: it pays for the travel, the weather, and the risk.
Inside Wireman vs Outside Lineman: Side by Side
| Factor | Inside Wireman | Outside Lineman |
|---|---|---|
| What you build | Building electrical systems — conduit, panels, lighting, controls | The grid — transmission & distribution lines, poles, towers, substations |
| Where you work | Job sites, mostly indoors or on structures under roof | Everywhere the lines run — rights-of-way, roadsides, remote terrain |
| Apprenticeship length | 5 years | ~3.5 years / ~7,000 hours |
| Who runs it | Local IBEW-NECA JATC (electrical training ALLIANCE curriculum) | Regional line constructor JATCs (ALBAT, Northwest Line, Southeastern, Cal-Nev) |
| Physical demands | Demanding — bending pipe, pulling wire, ladders and lifts | More demanding — climbing, rigging, heavy gear at height |
| Weather exposure | Some, especially early construction phases | Constant — heat, cold, rain, and storm restoration when it is worst |
| Travel | Usually home every night; travel is optional | "Following the work" is normal — long stretches on the road |
| Typical pay level | Strong union scale | Generally higher base + per diems in the same region |
| Lifestyle fit | Steady home life, variety of building work | Adventure, storm calls, and a paycheck that follows the miles |
How to Choose
My honest take after 13 years inside: if being home every night matters to you, or you want the widest variety of electrical work — controls, data, healthcare, industrial — go inside. If you want to be outdoors, don’t mind living out of a hotel or a camper for months following the work, and the idea of restoring power after a hurricane sounds like a calling instead of a nightmare, the outside will pay you more to do it. Neither is the “better” trade. They select for different people.
Whichever direction you lean, start by finding the program near you on the IBEW locals directory — inside applications go through your local’s JATC, while outside applications go to the regional line constructor JATC covering your area. And for the inside route, the aptitude test is the first gate, so prep for it seriously.

Frequently Asked Questions
Do linemen make more than inside wiremen?
Generally, yes. In most regions, outside linemen earn a higher base rate than inside wiremen, and travel jobs typically add per diems on top of the check. The Bureau of Labor Statistics tracks line installers and repairers as a separate, higher-paying occupation than electricians. The trade-off is that the extra money usually comes with heavy travel, storm work, and greater physical risk — many linemen are away from home for long stretches following the work.
Is the aptitude test the same for inside wireman and outside lineman apprenticeships?
The inside wireman apprenticeship uses the electrical training ALLIANCE aptitude test — algebra and reading comprehension, scored on a 1–9 scale, with most locals requiring a 4 or higher to qualify for an interview. Outside lineman apprenticeships are run by regional line constructor JATCs like ALBAT, and their selection processes vary: many use a similar aptitude test, but requirements like a Class A CDL and climbing ability carry more weight than they do on the inside. Check the specific JATC you are applying to.
Can you switch from inside wireman to outside lineman (or the other way)?
Yes, but there is no automatic transfer — they are separate classifications with separate apprenticeships. An inside journeyman who wants to go outside typically applies to a line constructor JATC and completes the outside apprenticeship, though prior electrical experience can help in the ranking process. Some linemen come inside later in their careers when they want off the road. Plenty of people have done both; just expect to earn the second ticket rather than trade one for the other.
Which apprenticeship is longer, inside wireman or outside lineman?
The inside wireman apprenticeship is typically 5 years, run through local IBEW-NECA JATCs using the electrical training ALLIANCE curriculum. Outside lineman apprenticeships are typically around 3.5 years / roughly 7,000 hours, run by regional line constructor JATCs such as ALBAT, Northwest Line JATC, Southeastern Line Constructors, and the California-Nevada JATC. Both pay you to work while you learn.
Do you need a CDL to become an outside lineman?
Most line constructor JATCs require apprentices to obtain a Class A CDL during the apprenticeship (some want a permit before you start), because line crews drive bucket trucks, digger derricks, and other heavy equipment between job sites. Inside wireman apprenticeships have no CDL requirement. If you are considering the outside, getting your CDL permit early is one of the best ways to strengthen your application.
Is being a lineman more dangerous than being an inside electrician?
Statistically, yes. Line installers and repairers work on energized transmission and distribution systems at height, in all weather, often during storm restoration — and the occupation consistently falls into a higher fatality-risk category than inside electrical work. Inside work has real hazards too (arc flash, falls, live panels), but the exposure profile outside is more severe. Both trades train safety relentlessly; the outside simply has less margin for error.
