systems, which provides light, heat, communications, and power to a variety of new and existing
residential, commercial, and industrial structures.

  Q1 y6 {$ z0 ?/ O" [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

relays, circuit breaker panels, and fuse enclosures, install single and multi-wire cables above and
underground, install data cabling, and install and maintain fibre optic and signalling systems.

all weathers; inside in dusty industrial plants and mills; to state-of-the-art clean-rooms in hospitals and
manufacturing plants. The work often requires considerable standing, bending, crawling, lifting,

With advances in technology the work of the construction electrician is changing. Today’s
wired environment requires construction electricians to be able to install a variety of wiring such as data,
audio, video, signalling, and communication cabling. Electrical control systems are also becoming more
complex, often solid-state or computer-controlled, which requires the construction electrician to have a
