SCOPE OF THE CONSTRUCTION ELECTRICIAN OCCUPATION; F6 C2 x( g' K) i8 ~
The title “construction electrician” defines a person who, because of his or her knowledge,

residential, commercial, and industrial structures.7 ?/ Y( V: r: {6 C
Construction electricians read and interpret electrical, mechanical, and architectural drawings, Y: _# K# @. B$ A- n& v
and electrical code specifications to determine wiring layout. They cut, thread, bend, assemble, and
