Inside wireman: what the job is and how the apprenticeship works

By the nodiexam team Updated

An inside wireman is the IBEW and NECA name for a commercial and industrial electrician, the person who installs power, lighting, controls and other electrical equipment in commercial and industrial buildings. The apprenticeship is paid work with a union contractor plus classes, and it takes four or five years, depending on the JATC.

Inside wireman is one of the classifications the IBEW and NECA train for. The electrical training ALLIANCE (etA), which writes their national training program, says inside wiremen install the power, lighting, controls and other electrical equipment in commercial and industrial buildings. Local committees called JATCs run the apprenticeships. In everyday terms, it is the union name for a commercial and industrial electrician.

What an inside wireman does

The work covers most of what a building needs to run on electricity. As one program lists it, NIETC's inside electrician apprentices wire homes and small apartment buildings, commercial, school and hospital buildings, industrial plants, and low-voltage systems such as fire alarm and data. Boston's program describes it as installing conduit and wiring lighting, switches, converters and larger electrical systems.

The conditions vary with the job: Boston says inside wiremen work outdoors in mud, cold and rain as well as in offices, hospitals and plants, and the work means crawling, lifting and climbing ladders and scaffolding. You work for a union electrical contractor, and the JATC assigns you to one.

The four IBEW classifications

In its overview, the etA names four kinds of IBEW and NECA electrical work, each with its own apprenticeship, outside linemen, inside wiremen, VDV installer technicians and residential wiremen.

ClassificationWhat they install, per the electrical training ALLIANCE
Inside wiremanPower, lighting, controls and other equipment in commercial and industrial buildings
Outside linemanThe distribution and transmission lines that carry power from the plant to homes and businesses
VDV installer technicianPhone, network, video, security and other low-voltage systems
Residential wiremanAll the electrical systems in houses and apartment buildings

If you are weighing the outside path, inside wireman vs lineman sets the two side by side.

How long the apprenticeship takes

The Bureau of Labor Statistics says most electricians learn the trade in a 4- or 5-year apprenticeship, with about 2,000 hours of paid on-the-job training each year. Inside programs set their own term:

ProgramTerm of the inside apprenticeship
NECA-IBEW Electrical Training Center (NIETC), Portland, Oregon8,000 hours on the job, plus 10 terms of school, one day a week
North Texas Electrical JATC, Dallas8,000 hours on the job, plus 720 hours of related instruction
Northwest Washington Electrical Industry JATC8,000 hours for inside wireman, 4,800 for limited energy and 4,000 for residential wireman
Boston Electrical JATC, IBEW Local 103five years, with 10,000 hours on the job and 1,000 hours of classroom instruction, in class one day a week
Denver JEATC, IBEW Local 68four years, working a standard 40-hour week with classes in the evening twice a week

Also, Minneapolis, Local 26 in the Washington, DC area and Ann Arbor all describe five-year inside programs. School runs the whole way through, and the schedule differs. Some programs teach one day a week during work hours, others in the evenings. You keep working full time either way, so plan for long weeks.

Pay while you train

You are paid from the first day, as a share of the local journeyman rate that rises in steps. The journeyman rate is local. At NIETC in Oregon it is $65.50 an hour from January 1, 2026. At Minneapolis it is $62.00 an hour, wages effective May 1, 2026. Both are before benefits. For all electricians nationwide, union or not, the median was $63,190 a year, or $30.38 an hour, in May 2025, according to the Bureau of Labor Statistics. IBEW apprentice pay shows how the steps work, with more local sheets.

The license at the end

Electrician licenses are issued by states, and the apprenticeship is how many people qualify for one. For example, on finishing, NIETC apprentices can take the state journey-level license exam, and Boston's inside wireman apprenticeship leads to the journeyman electrician "B" license. Denver goes further and makes earning the journeyman license a requirement of finishing its program.

How to get in

As a baseline, the etA lists typical requirements as age 18, a high school education, one year of high school algebra, a qualifying aptitude test score and being drug free. Each JATC adds its own rules and its own application dates. The usual order is:

  1. Apply to the JATC for the area where you want to work. How to join an IBEW apprenticeship walks through it.
  2. Take the aptitude test. Many programs use the electrical training ALLIANCE test, algebra and reading with no calculator. Some, such as Boston and Minneapolis, use the GAN test instead. The IBEW aptitude test page has the format and published cutoffs.
  3. Interview , or at some GAN programs, fill in a written form. See the IBEW interview.
  4. Wait on the ranking list until your number is called. See the IBEW ranking list.

Inside wireman or residential wireman?

Residential wiremen work on houses and apartment buildings only, and their program is shorter. In the Washington standards in the table above, residential wireman takes 4,000 hours against 8,000 for inside wireman. Entry can be easier too, because some Washington programs set no aptitude cutoff for residential wireman, and Puget Sound uses residential scores for counseling only. The inside program adds commercial and industrial work and takes longer. Not every JATC offers a residential program, so check yours.

Questions people ask

Is an inside wireman the same as an electrician?

Yes. Inside wireman is the IBEW and NECA name for a construction electrician who works in commercial and industrial buildings. Boston's program, for example, calls it inside wireman (electrician), and finishing it leads to a state journeyman electrician license.

How long is the inside wireman apprenticeship?

Four or five years, set by each JATC. NIETC in Oregon and North Texas ask for 8,000 work hours, Boston asks for 10,000 hours over five years, and Denver describes a four-year program. School runs alongside the work the whole time.

How much does an inside wireman make?

Pay is set by each local's contract. A journeyman inside wireman earned $65.50 an hour at NIETC in Oregon from January 2026 and $62.00 at Minneapolis from May 2026, plus benefits, and apprentices earn a rising share of that. IBEW apprentice pay has the steps and more sheets.

What is the difference between inside wireman and residential wireman?

Residential wiremen specialize in houses and apartment buildings, and their apprenticeship is shorter. In Washington's registered standards it is 4,000 hours against 8,000 for inside wireman, and some programs there set no aptitude cutoff for it.

Do I need electrical experience to start?

No. The electrical training ALLIANCE's typical requirements are about age, school, algebra, the aptitude test and drug testing, with no electrical experience asked. Trade experience can still help your interview score and your rank.
