What 電気工事士 do
An English description is being prepared. Japanese description:
情報の伝達設備である放送通信施設、インターホン、防災防犯などの設備、電話や通信の回線を納める配管、避雷針の工事なども行う。
基本的な作業は、機器の据え付け、器具の所定個所への取り付け、それらの機器や器具への配線などで、建設作業と並行して行われることが多い。作業は通常、2～4人のグループで行われ、それぞれのグループは職長が中心となり、その指揮下で作業が進められる。大きな建設現場では、電気工事の責任者がいて、グループごとの1日の作業内容が決められ、指示が与えられる。指示は通常図面によって示されるので、電気工事士はその図面を読解し、それに基づいて材料、工具、作業手順などを決めて作業を進める。全部の作業が終了すると、確認のために必ず試験を行って、試験成績書を作成する。
電気工事は様々な法令によって基準が定められており、法令を守って安全確実な仕事をすることが必要である。
◇ よく使う道具、機材、情報技術等
分電盤、配線、工具（かなづち、のこぎり等の手動工具、ドリル等の電動工具）、作業中の保護具（ヘルメット、ゴーグル、グローブ、安全靴等）

What drives the annual growth rate
Projected pay = current pay × (1 + annual growth)^years. The annual growth rate starts from a base wage-growth rate and adds or subtracts labor demand (the job-openings-to-applicants ratio), wage momentum and AI replacement risk for each occupation. Projections are not guarantees. How it is calculated →

Will AI replace 電気工事士? AI replacement risk
How AI is changing this job
A written analysis for this occupation is being prepared.
AI replacement risk compares the parts of a job that are easy to hand to AI or software (processing information, documentation, repetitive computer work) with the parts that are hard to automate (physical work, working closely with people, judgment in unpredictable settings), using the MHLW job tag survey on work activities, work context, skills and knowledge. The result is a relative position among all occupations in the country, scaled to 0–100%. Methodology →
Labor demand for 電気工事士
A ratio above 1.0 means there are more job openings than applicants (a labor shortage). The 5- and 10-year figures are estimates from the openings ratio, wage momentum and AI replacement risk.
