The underground lineman career path runs from groundman through apprentice, journeyman, cable splicer, and into foreman and superintendent slots that clear six figures without climbing a pole. This page lays out what each step pays, what certs move you up, and where the underground work is right now.
Underground linemen install, maintain, and repair cable systems below grade. The work splits three ways: underground residential distribution (URD), commercial and industrial primary, and underground transmission. On any given day you might pull 1,000 feet of 15kV concentric neutral through duct bank, splice a fault on a 25kV feeder in a manhole, swap a pad-mount transformer in a subdivision, or chase a fault with a thumper and TDR.
Voltage classes you will see: secondary (120V to 600V), primary distribution (4kV, 12kV, 15kV, 25kV, 35kV), and underground transmission (69kV through 500kV) on cross-linked polyethylene (XLPE) or high-pressure fluid-filled (HPFF) pipe-type cable.
Overhead crews work poles, hot sticks, and buckets. Underground works trenches, vaults, manholes, and pad-mount switchgear. The trade-offs are real:
Plenty of overhead JLs cross to underground at 45 or 50 when the climbing stops paying back. The work is steadier but slower.
Entry point. You handle cable reels, run the tugger, jackhammer trench, dig around live facilities by hand, and pull tape. Pay runs $20 to $28 per hour at most contractors. Most apprenticeship lists pull from groundmen first because foremen recommend the guys who already show up.
A registered DOL apprenticeship through an IBEW JATC, a utility-direct program, or an NRECA-affiliated co-op. 7,000 on-the-job hours plus roughly 700 classroom hours over 3.5 to 4 years. Some IBEW locals run dedicated underground apprenticeships; others train both overhead and underground under one ticket. Local 3 NYC and Local 1 St. Louis are known for separate cable splicer programs.
After top-out you can run a job, terminate, splice, troubleshoot faults, and operate switchgear. Journeyman pay ranges $40 to $70 per hour depending on local agreement and region. ConEd and PG&E underground JLs sit at the top; co-op underground guys in Texas, Oklahoma, and the rural Midwest sit at the bottom.
Cable splicing is a separate classification in many locals. You earn it by getting certified on specific systems: 3M cold shrink, Raychem heat shrink, Elastimold molded rubber separable connectors, and HPFF/pipe-type for transmission. Local 3 transmission splicers run north of $80 per hour with package. Splicers also pull the bulk of premium emergency callout work because nobody else can fix what they fix.
Foreman runs the crew, signs off on prints, owns the safety brief, and deals with the customer or system operator. General foreman runs multiple crews on a project. Foreman pay typically stacks 10% to 25% on top of JL scale.
Office-adjacent. Runs jobs across multiple GFs, owns the budget, and works directly with utility engineering. $130,000 to $220,000 base for IOU undergrounding programs and major underground contractors. The PG&E undergrounding program is currently hiring superintendents at the high end of that band.
| Step | Role | Tenure / Hours | Hourly Range |
|---|---|---|---|
| Pre-apprentice | Groundman / Material Handler | 0 to 12 months | $20 to $28 |
| Steps 1 to 3 | Apprentice (early) | 0 to 3,000 hrs | $24 to $40 |
| Steps 4 to 6 | Apprentice (late) | 3,000 to 7,000 hrs | $32 to $52 |
| JL | Journeyman Underground Lineman | Topped out | $40 to $70 |
| JL Splicer | Certified Cable Splicer | 1+ year as JL | $50 to $85 |
| Foreman | Crew Foreman | 2+ years JL | +10% to 25% over JL |
| GF | General Foreman | 5+ years foreman | $55 to $95 |
| Super | Superintendent | 10+ years | $130k to $220k base |
Highest underground scales nationally: Local 3 NYC, Local 103/104 Boston, Local 1245 Northern California, Local 1 St. Louis, LADWP. Lowest: rural co-ops in TX, OK, KS, and the Dakotas. Per diem on out-of-town underground transmission work runs $90 to $200 per day on top of base.
The certs below are the ones that change your hourly rate or get you onto specialty crews. Stack them in this order:
A pipe-type cert plus 5 years JL experience puts you in the top 5% of the trade by earning power.
Underground hiring concentrates in dense urban and suburban service territories. Right now the heaviest hiring sits here:
If you want to stay home and run consistent 40-hour weeks, underground in any of those markets beats overhead transmission travel. If you want $200k years, transmission cable splicing on PG&E or ConEd transmission projects gets you there.
Pros of underground:
Cons:
In some IBEW locals, yes. Local 3 NYC and Local 1 St. Louis run dedicated cable splicer apprenticeships. In most utility-direct programs you train on both overhead and underground and specialize after top-out.
Certified cable splicers in major metros earn $50 to $85 per hour base. Local 3 NYC transmission splicers exceed $80 per hour with package. Co-op and rural splicers run $40 to $55 per hour.
Some cross-trained programs still require pole-top and bucket rescue training plus basic climbing certification. Day-to-day climbing is rare. Knee, back, and hand work dominate instead.
3.5 to 4 years through a registered apprenticeship: 7,000 OJT hours and around 700 classroom hours. Cable splicer certifications add 6 to 18 months after you get your JL ticket.
Different hazards. Lower fall risk, higher arc flash and confined space risk. The fatality rate runs lower than overhead per BLS data, but burn injuries from arc faults inside vaults and manholes happen more often.
Topped out, underground cable splicers in NYC, Boston, San Francisco, and LA outearn overhead JLs by $10 to $25 per hour. In rural and southern markets, overhead with regular storm work outearns underground.
