This was originally a Royal Navy term for those trained and competent in the installation and maintenance of ships electrical systems.
A distinctive propeller insignia is worn to identify these personnel.
Training is provided in the National Maritime College of Ireland (incorporated into the Cork Institute of Technology).
Prior to its closure (in 1998), a number of electrical artificers were trained in the Irish Army Apprentice School and transferred to the Naval Service on completion of training.
The highest possible rank is 'warrant officer EA' of which there is only one in the Irish Naval Service.
