A cable splicer is a line-work specialist who joins, terminates and tests underground power cable — building the splices that connect cable sections to each other and the terminations that connect cable to the equipment at each end.
It is its own apprenticeship track inside line construction — ALBAT's cable splicer program runs 7,000 hours of on-the-job training — and it is a different job from the telecom and fiber-optic splicing done on the low-voltage side of the industry.
What is a cable splicer?
A cable splicer works on the cable itself.
On underground power systems, runs of cable have to be joined end to end, brought up risers, and connected to the equipment at each end, and doing that — splicing, terminating, and fault-finding and testing on de-energized underground cable — is the job.
A splice joins two cable sections into one continuous run; a termination ends a run onto a piece of equipment.
The clearest sign that this is its own job, not a task inside someone else's, is the apprenticeship structure.
ALBAT — the American Line Builders JATC, tied to the IBEW's 4th and 6th districts — runs cable splicing as a distinct apprenticeship program requiring 7,000 hours of on-the-job training, the same hour tier as its outside line and substation programs, with transmission and URD apprenticeships at 4,000 hours and traffic signal at 6,000.
Cable splicing belongs to line-work careers — outside line construction, which the IBEW/NECA apprenticeship system treats as its own specialty area with its own program, separate from the inside-wireman track.
It also shares its name with a telecom occupation the federal taxonomy files under a different code; the next section sorts out the difference.
What does a power cable splicer do?
The clearest published picture of the skill set comes from the apprenticeship that teaches it.
ALBAT's cable splicer apprentices are trained to:
- find and test faults on de-energized underground cable
- terminate primary underground cable
- splice with rubber kits and tape in manholes
- splice lead cable — joining lead cable to XLP or EPR cable — in manholes and risers
Two words carry most of that list.
A splice joins two cable ends so the run works as one cable; a termination ends the run at equipment.
Both are done to exacting standards because the joint is buried, submerged or sealed in a structure where nobody can casually inspect it afterward.
Because the workspace is often literally underground, federal rules shape the job directly.
Under 29 CFR 1910.269(e), OSHA treats a manhole, vault, tunnel or shaft that has limited egress and is designed for periodic entry as an enclosed space, and it requires employees who enter one — or who serve as attendants — to be trained in the hazards of enclosed-space entry, in entry procedures and in rescue procedures.
That is what the rule requires of employers, described here as career context, not safety instruction.
Power cable splicer vs telecom and fiber splicer
The confusion is real, and the federal taxonomy feeds it.
O*NET lists both "Cable Splicer" and "Fiber Optic Splicer" as sample job titles under Telecommunications Line Installers (SOC 49-9052), an occupation whose tasks include splicing cables and laying underground cable.
So a posting that says "cable splicer" can belong to either trade, and the title alone does not tell you which.
The power cable splicer is the job this page describes: underground power cable on utility systems, trained through the outside-line side of the trade — ALBAT's 7,000-hour cable splicer program is the worked example.
The skill set is power-cable work: primary terminations, rubber-kit and tape splices, and lead-to-XLP or lead-to-EPR splicing.
Telecom and fiber splicing is a different side of the industry — low-voltage and structured-cabling work under a different occupation code (49-9052).
The overlap that keeps the confusion alive is the work language: the telecom occupation's tasks include splicing cables and laying underground cable, while the power side's training covers splicing in manholes and risers.
So "underground" in a posting does not settle the question either.
For the signal side of the trade more broadly — structured cabling, fire alarm, access control and AV — see low-voltage technician careers.
Where do cable splicers work?
The employers are the ones that own and build underground power systems.
Cable splicing sits inside the line-work occupation, and BLS's employer breakdown for that occupation shows where the work lives: of about 131,900 power-line installer jobs in 2025, 50% were in utilities, 29% in utility system construction, 10% in local government, 6% in specialty trade contractors and 2% in federal government.
The settings are the underground parts of those systems: manholes and risers on distribution networks.
Underground distribution is a routine part of the trade rather than a niche — in the electrical training ALLIANCE's job analysis of journey-level outside linemen, 69% reported installing and maintaining underground distribution.
Training is regional, because outside-line apprenticeships are.
ALBAT runs dedicated Cable Splicing programs alongside Outside Line, Substation, Traffic Signal, Transmission and URD programs, serving Illinois, Indiana, Kentucky, Maryland, Michigan, Ohio, Virginia, Washington D.C. and West Virginia.
Wherever you are, the program that covers your region is the one whose standards and entry rules actually apply to you.
How do you become a cable splicer?
The route is an apprenticeship with a line-side program, and cable splicing is taught inside it.
ALBAT's cable splicer apprenticeship requires 7,000 hours of on-the-job training, and ALBAT describes its apprenticeship length as approximately 3 to 3½ years, tracked by OJT hours, with advancement roughly every six months.
Registered apprenticeship also sits under a federal rule.
29 CFR 29.5, the Department of Labor's rule for registered programs, requires a certificate of completion issued by the registration agency and sets a floor of 2,000 hours of on-the-job learning for time-based programs.
Program standards then set their own totals — ALBAT's 7,000 hours for cable splicers is more than three times that floor.
Entry and selection are the program's own too.
ALBAT's published applicant requirements include a valid Class A CDL or Class A CDL permit at the time of application, plus a high school diploma or GED (or an associate degree or higher).
Selection runs through an aptitude test and an interview, and applicants sit on a ranking list that stays live for up to one year.
What you learn along the way is the skill set from the section above: fault-finding and testing on de-energized cable, primary terminations, manhole splicing with rubber kits and tape, and lead-to-XLP or lead-to-EPR work.

How much do cable splicers make?
Federal wage data does not track cable splicers as their own occupation — there is no cable-splicer line in the BLS pay tables.
The published proxy is Electrical Power-Line Installers and Repairers (SOC 49-9051), the broader line occupation splicing sits inside, and that is the occupation the cable splicer salary page reports: BLS OEWS May 2025 medians and percentiles for the United States and by state.
Find cable splicer jobs
BLS publishes no cable-splicer projection; the closest is the line occupation's.
BLS projects employment of electrical power-line installers and repairers to grow 10 percent from 2025 to 2035 — "much faster than the average" — naming rising electricity demand, new development, AI data centers and grid upgrades among the drivers.
Openings sit on the line-work side of the industry, with utilities and utility system construction employing the largest shares of the occupation, per the employer mix above.
When you are ready to look, browse cable splicer jobs on ElectricianHires, and keep the wider line-work listings in view — federal wage data counts splicing inside the line-work occupation rather than as its own line item.
