Construction electricians work in the full range of environmental conditions: from outside in

manufacturing plants. The work often requires considerable standing, bending, crawling, lifting,

the materials and techniques of construction. All construction electricians are required to be competent in

On small jobs, construction electricians may work alone with minimal supervision, and they% m _! {) H6 H& [! B- \$ E
may supervise an apprentice. On large jobs, they may work under the direction of a supervisor.8 h) v* O- p, R; P8 x* c- f
