An electrical apprentice works directly under the supervision of a qualified Journeyman Electrician in installing or maintaining a variety of approved wiring methods for distribution of electrical light, heat, power, radio, and signaling utilization systems. The work is performed in existing or new residential, commercial and industrial buildings and includes street and highway lighting, traffic signal and other outdoor above and below grade installations. The trade requires considerable physical effort on the part of the apprentice to do lifting, climbing, crouching, and working in cramped areas.
