residential, commercial, and industrial structures.
Construction electricians read and interpret electrical, mechanical, and architectural drawings
and electrical code specifications to determine wiring layout. They cut, thread, bend, assemble, and
install conduits and other types of electrical conductor enclosures and fittings. They pull wire and cable
