Lineman Interview Questions
& Model Answers, 2026

Test for absence of voltage, then install grounds so that you work inside an equipotential zone: grounds applied on the source side and on all sides that could be energised, bonded together and to the structure or a grounded bucket, cluster or bracket grounded, with the shortest, largest-section leads you can use. The point is not to drain the line to earth, it is to keep everything you can touch at the same potential if the line is re-energised. Candidates who describe grounding as 'draining it to ground' misunderstand the physics that keeps them alive.

Gloving is used at distribution voltages where rated rubber gloves and sleeves plus thorough cover-up allow direct contact within the approach distance; hot-stick work is used at higher voltages and where cover-up is impractical, keeping the worker outside the approach distance entirely. A good answer mentions the utility's own work rules governing the choice, glove testing and air-testing intervals, and that you never glove without full cover-up in place first.

Match impedance and voltage ratings, confirm the primary configuration available, connect the primaries and secondaries in the required configuration for the service — delta or wye on each side — and pay attention to polarity and phasing on the secondary before closing anything in. Phase and voltage-check before energising the customer. Mentioning that a mismatched impedance bank will circulate current and that a wrong secondary connection can destroy the bank shows real experience.

Approach distance is the closest any part of you, your tools or your conductive equipment may come to an energised part at a given voltage, and it grows with voltage. Maintaining it means positioning the truck and boom deliberately, using an insulated boom and observing its rating, having a dedicated spotter for crane or digger work near lines, and covering up anything within reach before you get within the distance. Say you would refuse a set-up where the distance cannot be maintained.

Sound the pole with a hammer and look for a dull response, probe near the groundline for rot, check for shell rot, woodpecker damage, cracks, previous burn marks, and check whether unbalanced tension or a broken guy is loading the pole. Assess the hardware and the framing above before committing weight. If it fails the inspection, it gets a bucket, a crane hold or a replacement — not a climber. Poles that fail while climbed are a recurring fatality mechanism.

Work from a written switching order approved by the system operator: confirm the order, identify the correct device by number rather than by memory, operate in the sequence given, verify the device position visually, test for absence of voltage, apply grounds, and tag each isolation point. Confirm back to the operator at each step. A lineman who describes switching without an operator and a written order is describing a system-wide event.

Real triggers: cover-up you were not satisfied with, a grounding set-up that did not create an equipotential zone, a crew member reaching outside their cover, deteriorating weather with lightning in the area, or a pole that failed inspection. Say what you stopped, how you raised it with the foreman, and the corrected plan. Utilities screen hard for people who will use stop-work authority on their own crew.

The honest answer covers the mechanics of fatigue: sixteen-hour days for a week or more, unfamiliar territory, mutual-aid crews with different practices, and how you managed sleep, food, and the discipline to still ground every time. Add how you handled a foreign crew's different work methods. Bragging about how little you slept is a bad answer — storm fatalities cluster in exactly that mindset.

Line apprentices learn by graduated exposure, so a strong answer describes what you let them do and when: climbing and framing before any energised work, cover-up under direct watch, and never leaving them to make an approach-distance judgement alone. Describe a specific correction you made and how you made it without embarrassing them in front of the crew.

Linemen are the only utility employee most customers ever meet. The strong version keeps the crew safe first — asking the customer to stay back from the work area — then gives honest information about the restoration estimate rather than an optimistic one, and refers billing or claims questions to the utility rather than speculating. Answers that involve arguing with a customer at the truck are the wrong answers.

Line work has one of the clearest published anchors in the trades: the BLS OEWS May 2025 national median for electrical power-line installers and repairers is $95,320 a year ($45.83/hr), with the top 10% above $128,690. Say which classification you hold — apprentice step, journeyman, or crew leader — and whether you are quoting straight time, since storm and overtime hours substantially change annual earnings. Ask what the utility's or contractor's posted classification rate is.

Confirm the overtime threshold and multiplier, whether storm work is paid at double time after a set number of hours, the guaranteed minimum for a callout, how travel and standby time to a mutual-aid deployment are treated, and the per diem and lodging arrangements when you are working out of territory. For contractors, also confirm whether there is a subsistence payment and whether it runs on days weathered out.

Pension or retirement contribution and vesting, health coverage during storm deployments, the tool and climbing-gear provision including rubber goods testing, boot and FR clothing allowance and laundering, CDL costs and medical card renewal, employer-paid training toward journeyman or crew-leader classification, and the rotation for on-call. For travelling contract work, the per-diem structure often matters more than the hourly difference.
