SCOPE OF THE CONSTRUCTION ELECTRICIAN OCCUPATION. R/ T. T0 m7 _4 _' g
The title “construction electrician” defines a person who, because of his or her knowledge,

( ^4 C" U7 c! ZConstruction electricians read and interpret electrical, mechanical, and architectural drawings# Q; ?2 S9 V. e2 [8 H, C5 t
and electrical code specifications to determine wiring layout. They cut, thread, bend, assemble, and. g1 |* _1 I" P2 |4 ^/ t- s5 `# n/ L
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; I7 w7 l" }- N
underground, install data cabling, and install and maintain fibre optic and signalling systems.( v4 X: w& m& k' F8 z8 j% G
Construction electricians work in the full range of environmental conditions: from outside in

manufacturing plants. The work often requires considerable standing, bending, crawling, lifting,/ J* n, z/ F$ k+ T H4 H! l
climbing, pulling, and reaching and may be conducted in cramped, confined spaces or on ladders and

Construction electricians are required to have good mechanical ability, a thorough E3 f* ^- S/ i# \) f
knowledge of the principles of electricity, circuitry, and power distribution systems, and familiarity with) e: y" U7 c) |0 P9 i( n
the materials and techniques of construction. All construction electricians are required to be competent in
' ^( u6 I9 @/ I, R2 G6 Cthe use of hand and power tools and test equipment.
7 N& f6 u& G# E6 RAll electrical wiring and installations must conform to the CSA Canadian Electrical Code.

On small jobs, construction electricians may work alone with minimal supervision, and they& ]4 }; y1 K6 x) k, T
may supervise an apprentice. On large jobs, they may work under the direction of a supervisor.* O+ X+ e7 P0 ~1 B+ Y9 v4 A# \
Construction electricians interact and work co-operatively with the full spectrum of1 O- e. E% x/ `. p9 {% }
construction tradespeople, such as carpenters, lathers, cabinetmakers, plumbers, and heating, ventilation6 w" [" X0 o, ^; b
and air-conditioning technicians. They are required to constantly adjust their schedule and work to# t" s. ^( n" J X/ H) _+ W
accommodate the schedule of these other trades since most trades rely on some sort of electrical
