Compound of 電気(でんき) ('electricity') and 工事(こうじ) ('construction work'). A general term for any construction or installation task involving electrical systems.

Usage

  • Used both for major projects (wiring a new building) and small jobs (installing a new outlet or light fixture).
  • Because Japanese law restricts much electrical work to holders of the 電気工事士(でんきこうじし) license, signage and paperwork in this field frequently mention the word. Homeowners hire a 電気工事屋(でんきこうじや) ('electrical contractor') for such work.
  • Planned power outages due to building maintenance are commonly announced as 電気工事(でんきこうじ)のため停電(ていでん)いたします 'There will be a power outage due to electrical work'.
