Let’s say, a designer decided to utilize optical fiber cables for control of lighting circuits or to amalgamate wiring connecting the fire alarm field devices with wiring supplying the components of a security system. Is such integration of wiring allowed by the Canadian Electrical Code? And what about use of a nurse call panel in a hospital as means for annunciation of a patient room (sleeping room) smoke [...]

“What really does the code say about connecting premises wiring to supply lines? Where do I begin?” These are common questions when one is planning the electric supply to a new building or structure.

(No Ratings Yet)In the September/October editorial, I wrote that the Dallas Morning News had reported that the city of Dallas would not cut code enforcement departments in balancing the budget. It was my impression from that article that “building inspectors—electrical, plumbing, mechanical, and building—and fire inspectors were specifically singled out as those that would NOT be cut.” [...]

All electrical practitioners know too well that water and electricity do not mix. Results of such mixture are quite hazardous. This is the reason that the CE Code mandates GFCI protection of receptacles and permanently connected electrical equipment installed in proximity to water (i.e., pools, bathtubs, sinks, shower stalls, etc.). This is also the reason [...]
