How to say "electrician" in Japanese

• 電工でんこうCommon
  nounA shortened form of 電気工 and the common word for an electrician — a worker who installs and repairs electrical wiring and equipment. Use it for the tradesperson you call about wiring problems.
• 電気工でんきこう
  nounThe full form of 電工, covering the same tradesman sense of electrician. It is less common, however, so you will mostly encounter, and should usually write, the shortened 電工.
• 電気技術者でんきぎじゅつしゃ
  nounThis word chiefly denotes an electrical engineer — a specialist in electrical technology — and covers electrician only secondarily; for the tradesman who works on wiring, 電工 is the word you want.
• 電気技師でんきぎし
  nounLike 電気技術者, this primarily means electrical engineer, with electrician as a secondary sense; it is seldom the word you want for the tradesman who installs or repairs wiring.

For the tradesman who installs or repairs wiring, use 電工, the common word (電気工 is its less common full form); 電気技術者 and 電気技師 chiefly mean electrical engineer, with electrician only a secondary sense.
