What does a Safety Codes Officer look for during a Calgary electrical inspection?

A Safety Codes Officer inspects your electrical work against the Canadian Electrical Code (CEC) as adopted under the Alberta Building Code, checking everything from wire sizing and connection quality to proper protective device ratings and grounding. The inspection is thorough and systematic — these officers are certified by the Safety Codes Council and trained to catch both obvious violations and subtle deficiencies that could create fire or shock hazards.

The inspection begins with the electrical panel, which is the heart of your home's electrical system. The officer verifies that breaker sizes match wire gauges — a 15A breaker on 14-gauge wire, 20A on 12-gauge, and so on. They check that the panel is properly labelled, that all connections are torqued to specification, that the grounding and bonding are correct, and that the panel has adequate space and accessibility. For panel upgrades, they verify the service entrance cable sizing, the meter base connection, and coordination with ENMAX standards.

Wire routing and protection receives close attention. The officer checks that NMD90 cable is properly supported with staples at the required intervals, that cables passing through studs or joists are protected with nail plates where required, that all junction boxes are accessible (never buried behind drywall), and that wire fill in boxes meets code calculations. They look for improper splices, wiring run outside of approved methods, and cables that are damaged or improperly supported.

Protective devices are a major focus. The officer verifies that GFCI protection is installed in all required locations — bathrooms, kitchens within 1.5 metres of the sink, garages, outdoor outlets, and unfinished basements. They check that AFCI protection is installed where required by current code, particularly on bedroom circuits. For EV charger installations, they verify the dedicated circuit sizing, the charger's listing and installation per manufacturer specifications, and proper disconnecting means.

Grounding and bonding is checked throughout the installation. Every metal box, every ground wire, every bonding connection must be complete and properly terminated. The officer verifies the main grounding electrode connection, bonding of the water piping system, and proper ground continuity throughout the new circuits. In Calgary's climate, where chinook-driven thermal cycling can loosen connections over time, proper torque on screw terminals is especially critical. The officer also checks smoke and CO alarm circuits, fixture ratings for their locations, outdoor installation weatherproofing, and overall workmanship. If deficiencies are found, your electrician corrects them and schedules a re-inspection.
