AI exposure: Electrical and Electronics Repairers, Powerhouse, Substation, and Relay
Inspect, test, repair, or maintain electrical equipment in generating stations, substations, and in-service relays.
Reading this score
computed32.5% of this occupation's weighted task load is exposed, which puts Electrical and Electronics Repairers, Powerhouse, Substation, and Relay at the 56th percentile of 923 occupations. The capability is largely there. Its average task scores 1.9 out of 4 on what a current system can produce, and the frictions that hold other jobs in place are comparatively weak here.
What holds the line here is embodiment. Across this occupation's 15 tasks it averages 1.73 out of 3, the highest of the five friction dimensions. In plain terms, the work has to happen in physical space. A language model cannot move matter. Until the robotics to do this work is both good enough and cheap enough to deploy widely, capability in software does not reach it.
The most exposed thing this job does is Prepare and maintain records detailing tests, repairs, and maintenance, at 73.3%. The least is Disconnect voltage regulators, bolts, and screws, and connect replacement regulators to..., at 0.0%. A gap of 73.3% between two parts of the same job is the reason this index publishes at task level. An occupation-wide number would have hidden both.
Within installation, maintenance and repair occupations, this one is more exposed than most. The median across the 50 roles in the group is 12.8%, and only 1 of them score higher than this. Occupational families are not uniform, and the spread inside them is often wider than the gap between them.
What would move this score. Of 15 tasks, 8 are currently banded exposed, 0 assisted and 7 untouched. For that distribution to shift materially would take capability alone, since there is little structural friction here to slow adoption once a system can do the work. The score is re-computed every quarter against a fresh capability reference, and the change is published rather than quietly applied.

Where the score comes from
judgedEvery task is scored through the standardised work activities it maps to. These are this occupation’s averages on the six rubric dimensions. Capability is what AI can do; the other five are what stands in the way.
| Dimension | Mean | Scale |
|---|---|---|
| Capability | 1.90 | 0-4 |
| Embodiment | 1.73 | 0-3 |
| Presence | 0.70 | 0-3 |
| Accountability | 1.10 | 0-3 |
| Context | 1.47 | 0-3 |
| Verification cost | 1.47 | 0-3 |
What this means in practice
Where most of a role's weighted task load is exposed, the work that survives is usually the part of the job nobody wrote into the job description: deciding what should be produced rather than producing it, and being answerable for the result. The tasks lowest on this page are a better guide to where to spend your time than any general advice about the future of work.

Read this carefully. Exposure is not displacement. A high score means current AI systems can produce this work, not that anyone will stop paying a person to do it. Adoption depends on economics, regulation and inertia that this index deliberately does not model. How the score is built.
