Electrical work varies by crew and assignment, and no single apprentice checklist applies to every U.S. job.
In most programs, you will eventually need a set of basic hand tools, a way to carry and protect them, and access to a properly rated test instrument. Safety glasses and other PPE are selected for the actual hazard, not simply because someone works in the electrical trade. Ordinary rubberized handles are not proof that a tool is insulated or safe near energized parts.

Start with the employer’s list, not a generic kit
Your first step is to obtain the written list from the contractor, union, or training center. Ask which items you must own, which items the employer supplies, and which tools are restricted to qualified personnel. Also ask whether the list is for residential construction, commercial work, industrial maintenance, utility work, or a particular classroom phase. Those distinctions change what you will use and what protection is required.

OSHA and NFPA guidance supports categories of tools and safe-work practices, but it does not establish one universal shopping list for every apprentice. A tool that is useful for rough-in may be unnecessary on a service crew, while test equipment and PPE may be selected by the employer for a specific task. Treat the list below as a planning framework to check against your actual assignment.

Core hand tools you are likely to use
Basic hand tools enable common layout, fastening, cutting, and conductor-preparation tasks. Buy only the sizes and types your program specifies, and select tools intended for the work rather than assuming a familiar-looking handle is electrically rated.
| Category | Typical use | What to verify before buying |
|---|---|---|
| Pliers | Holding, bending, and positioning conductors or hardware | Required styles and sizes; condition; insulation or markings if the tool could contact exposed energized parts |
| Diagonal cutters | Cutting conductors, ties, and small wire | Cutting capacity, jaw condition, and any employer requirement for insulated tools |
| Wire strippers | Removing insulation without damaging the conductor | Conductor-size range and whether a specific stripper style is required for assigned wiring methods |
| Screwdrivers | Installing devices, terminals, covers, and fasteners | Tip types and sizes; shaft condition; suitable insulation where contact with exposed energized parts is possible |
| Tape measure | Layout, box placement, and material measurements | Length, readability, durability, and any site preference |
| Tool bag or pouch | Carrying and organizing tools without loose items falling from height | Secure closures, attachment method, capacity, and compatibility with the employer’s storage rules |
Keep cutting edges, screwdriver tips, and plier jaws clean and undamaged. A damaged tool can slip, damage a conductor, or create an unexpected hazard. Do not modify a tool by grinding away markings or adding tape and then treating it as certified equipment.
Rubberized grips are not electrical insulation
OSHA’s Electrical Hazard student workbook explains that common rubber coating is often intended for comfort and grip. It does not, by itself, make a tool suitable for electrical work. OSHA’s 1991 interpretation similarly says tools such as screwdrivers and pliers must have insulation suitable for the conditions when they might contact exposed energized conductors or parts.
Look for the manufacturer’s permanent markings and documentation, and follow your employer’s rule for insulated tools. If a tool’s rating or intended use is unclear, do not use it around exposed energized parts. A soft handle, color, or “non-slip” description is not a substitute for a verified rating.
Test instruments: buy only what the task requires
A meter or voltage tester is not a universal permission slip to work energized. NFPA’s safe-work overview includes the step: verify absence of voltage using a properly rated test instrument. The instrument must be appropriate for the circuit and task, and the person using it must have the required training.
Rank #2
- Ergonomically Designed: Work in tight areas with a compact design that gets into tough spots
- Both tools are designed to fit into difficult to reach spaces
- Complete a wide range of applications with a high-performance motor that delivers up to 300 UWO, and an impact driver delivering up to 1,400 in-lbs of torque
- Both the DEWALT impact driver and drill driver feature integrated LED work lights with a convenient 20-second delay, ensuring enhanced visibility in dimly lit or challenging work areas
- One-Handed Loading - Keep one hand free with a 1/4 in. hex chuck that accepts 1 in. bit tips
Questions to answer before selecting a tester
- What instrument type does the employer or instructor specify?
- What measurements will you be trained to make, and on which systems?
- What rating and markings are required for those conditions?
- How will the instrument be inspected, maintained, and function-checked?
- Who is authorized to use it, and who provides leads, probes, or accessories?
Do not infer suitability from a low price, a familiar brand, or a claim that a device “detects electricity.” A non-contact detector may be useful for an initial indication, but it does not replace the properly rated instrument and procedure used to establish an electrically safe work condition. Follow the employer’s written procedure and training rather than improvising a test sequence.
Use a test instrument as part of a procedure
- Identify the circuit, equipment, and disconnecting means through the approved job plan.
- Apply the required controls and establish the electrically safe work condition procedure for the task.
- Use an instrument rated for the expected conditions to verify absence of voltage, following your training.
- Document or communicate the result as the employer requires before beginning the work.
The exact steps, boundaries, and authorization depend on the work and sector. If you have not been trained for the measurement or cannot confirm the instrument’s rating, stop and ask the qualified person supervising you.
PPE is selected by hazard assessment
OSHA’s electric-power PPE guidance gives examples that can include safety glasses, face shields, safety footwear, insulating rubber gloves with leather protectors, insulating sleeves, and flame-resistant clothing. Those examples are not a universal apprentice uniform. The employer must assess the hazards, provide training, discuss PPE during job briefings, and address inspection or testing requirements for applicable insulating equipment.
| PPE category | When it may be relevant | Selection checks |
|---|---|---|
| Safety glasses | Routine work where flying particles or fragments are possible | Required impact protection, side coverage, fit, and compatibility with other PPE |
| Face shield | Tasks with additional face or arc exposure identified by the assessment | Use with the required eye protection; confirm the employer’s specified protection level |
| Safety footwear | Worksites with foot, slip, or electrical hazards identified by the employer | Site requirements, fit, condition, and care instructions |
| Insulating gloves and leather protectors | Tasks requiring electrical insulation under the employer’s procedure | Correct class or rating, size, inspection, testing, storage, and protector compatibility |
| Insulating sleeves | Tasks where the hazard assessment identifies arm exposure | Applicable rating, inspection schedule, fit, and storage |
| Flame-resistant clothing | Tasks where thermal or arc hazards are identified | Employer-selected performance requirements, fit, condition, and laundering instructions |
Do not purchase gloves or clothing merely because they are marketed to electricians. Verify the markings and requirements with the person responsible for the program. Insulating PPE may require documented inspection and testing; storing it folded against sharp tools or using it after damage can defeat its protective purpose.
PPE is the last line of defense
NFPA’s “Learn More About NFPA 70E” overview states: "NFPA 70E emphasizes PPE as a critical safety measure, but while essential, it should be considered the last line of defense against electric shock and arc flash hazards rather than the first." In practice, hazard elimination, de-energizing, proper isolation, and safe work practices come before relying on clothing or gloves. PPE does not make otherwise unsafe energized work acceptable.

Portable power tools and cord safety
OSHA’s construction electrical guidance says to disconnect portable power tools before servicing them or changing accessories. Remove damaged tools from use rather than leaving them in the gang box. Avoid wet locations unless the tool is approved for that environment, and route cords so they are protected from damage and do not create trip hazards.
Do these 3 things before closing this tab:
1Fix the driver behind crashes, sound loss and screen glitches2Repair Windows errors before they cause bigger problems3Scan for outdated or missing drivers - takes under a minute- Inspect the housing, cord, plug, guard, switch, and accessory before use.
- Unplug or otherwise disconnect the tool before clearing a jam, changing a blade or bit, or performing maintenance.
- Tag and report damaged equipment according to the employer’s process.
- Keep cords away from sharp edges, heat, water, vehicles, and pinch points.
- Use only accessories and guards intended for the tool.
These are work-practice controls, not optional extras for a new apprentice. Ask how your crew identifies removed-from-service equipment so you do not accidentally put it back into circulation.
Non-tool essentials for your first weeks
Apprentices often ask what to bring besides tools. The most useful non-tool items support communication, training, and accountability rather than adding more equipment to your bag.
- A copy of the employer’s tool and PPE list, with items marked as employee- or employer-supplied.
- A pocket notebook or approved digital method for recording measurements, instructions, circuit identifiers, and questions.
- Training and authorization records required by the employer or program.
- A way to label personal tools and store them securely according to site rules.
- Access to the current safety procedures, emergency contacts, and job-briefing information.
- Any site-required clothing, identification, or communication device specified during orientation.
Do not bring personal test equipment or PPE to a job without confirming that the supervisor accepts it. Employer-controlled equipment may be inspected, calibrated, or tracked in ways a personal item is not.
How to decide between two tools or PPE items
When the approved list gives you a choice, compare products in this order:
Rank #4

These marking pencils are much thicker and stronger than normal pencils during the marking process of construction work, suitable for various surfaces, such as glasses, metal, boards, floors, walls, furniture, etc. The written marks can be easily wiped with a wet paper towel when needed
- Task fit: Does it perform the exact work you will be assigned?
- Verified markings: Are ratings, insulation claims, or applicable standards clearly marked and supported by documentation?
- Condition and integrity: Are handles, insulation, leads, lenses, seams, and closures free of damage?
- Ergonomics: Can you control it comfortably without excessive force or awkward wrist positions?
- Durability and repairability: Can worn parts be replaced, and can the item tolerate the site conditions?
- Cost within the approved category: Choose value only after safety and employer acceptance are established.
For PPE, add fit, care instructions, inspection intervals, and compatibility with other protection. For meters and testers, add the required rating, lead condition, verification process, and authorized-user rules. A cheaper item that cannot be accepted, inspected, or maintained is not a bargain.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.A practical buying sequence
- Request the current list. Get it from the employer, union, or training program, and ask what is supplied.
- Separate ownership from authorization. Mark basic hand tools, test equipment, and PPE separately; owning an item does not qualify you to use it.
- Buy the minimum approved hand tools first. Start with the categories needed for your first assignment rather than purchasing every specialty tool.
- Confirm test equipment in writing. Ask which instrument, rating, accessories, and inspection process apply.
- Complete orientation and training. Learn the job’s electrical-safety procedures before using a tester or entering a controlled work area.
- Inspect before each use. Remove damaged tools and PPE from service through the employer’s process.
- Expand only when the work changes. Add task-specific tools after a supervisor explains the need and accepts the item.
Common first-year mistakes and fixes
Buying a complete kit before seeing the job
Problem: You spend money on specialty tools that sit unused or conflict with the employer’s preferred equipment.
Fix: Buy the approved basic categories first and wait for task-specific instruction.
Treating colored or rubberized handles as insulated
Problem: Comfort material is mistaken for protection from energized parts.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Fix: Require verified markings and employer approval for any tool that could contact exposed energized conductors.

Using a tester without understanding the procedure
Problem: A detector or meter is used as if it alone establishes a safe condition.
Fix: Follow the trained identification, isolation, and verification procedure and ask the supervising qualified person when uncertain.
Assuming PPE replaces de-energizing
Problem: Gloves, glasses, or flame-resistant clothing are treated as permission to accept avoidable exposure.
Fix: Put hazard elimination and safe work practices first; use PPE as the final protective layer required by the assessment.
Keeping damaged equipment in circulation
Problem: A cracked handle, cut cord, damaged glove, or scratched lens is returned to the tool bag.
Fix: Stop using it, label or isolate it as directed, and report it for replacement or evaluation.
Reference material worth keeping
The OSHA resources titled “eTool: Construction – Electrical Incidents – Power Tools,” the 1991 interpretation on tools used near exposed energized conductors, the “Electrical Hazard student workbook” (2022), and the electric-power PPE eTool explain the distinctions between tool condition, insulation, work practices, and hazard-based protection. NFPA’s “Learn More About NFPA 70E” overview explains the hierarchy that places PPE after hazard elimination and safe work practices. If your program uses the NFPA 70E Handbook for Electrical Safety in the Workplace, use the edition and procedures designated by your employer or instructor.
