A commercial electrical inspection checklist covers every critical system your Calgary building’s electrical infrastructure must pass — from service panels and branch circuits to emergency lighting and grounding. Use this checklist to prepare for a City of Calgary Safety Codes inspection or schedule a professional audit with a licensed commercial electrician.
What Is a Commercial Electrical Inspection?
A commercial electrical inspection is a systematic review of a building’s electrical systems, performed by a licensed electrician or Safety Codes Officer. In Calgary, mandatory inspections are triggered by permits — new construction, service upgrades, renovations, and changes of use all require one. Periodic audits between permit milestones help Calgary business owners catch problems before they become costly failures.
The Alberta Electrical Safety Code (based on the Canadian Electrical Code, Part I) sets the minimum standard for all commercial electrical installations in Alberta. Every item on this checklist maps back to that code.
According to the Insurance Bureau of Canada, electrical fires are responsible for significant insured losses across Canada each year — many originating in commercial buildings where systems had not been formally assessed in years. A proactive inspection is far less expensive than a fire, a shutdown, or a failed safety audit.
The Complete Commercial Electrical Inspection Checklist
Use this checklist as a starting point before booking a professional inspection. Items marked as requiring a licensed electrician should never be self-assessed — always have a qualified Calgary commercial electrician evaluate those systems in person.
| # | Inspection Item | Who Checks It | Pass Criteria |
|---|---|---|---|
| 1 | Main electrical panel condition | Licensed electrician | No corrosion, breakers labelled, rated for load |
| 2 | Circuit breaker operation | Licensed electrician | All breakers trip and reset correctly |
| 3 | Branch circuit wiring condition | Licensed electrician | No exposed wiring, insulation intact |
| 4 | GFCI protection (wet locations) | Facility manager / electrician | GFCI outlets test and reset correctly |
| 5 | AFCI protection (where required) | Licensed electrician | Arc-fault breakers installed per CEC requirements |
| 6 | Grounding and bonding | Licensed electrician | All equipment grounded, bonding connections secure |
| 7 | Emergency lighting | Facility manager / electrician | Activates on power loss, illuminates for 30 minutes |
| 8 | Exit sign operation | Facility manager | Illuminated at all times, battery backup functional |
| 9 | Conduit and enclosure integrity | Licensed electrician | No cracks, open knockouts sealed, covers in place |
| 10 | Outlet and receptacle condition | Facility manager | No cracked covers, no loose outlets, correct polarity |
| 11 | Panel clearance (Alberta code: 1 metre) | Facility manager | 1 metre of clear working space in front of all panels |
| 12 | Electrical room access and labelling | Facility manager | Rooms locked, labelled “Electrical Room — No Storage” |
Electrical Panel Inspection Points
The electrical panel is the single most important component of any commercial electrical inspection. Calgary inspectors look for the following items on every panel assessment:
- Panel rating vs. actual load: The panel’s amperage rating must match or exceed the building’s calculated load. Overloaded panels are one of the most common violations found in older Calgary commercial buildings.
- Breaker condition: Double-tapped breakers (two wires on one breaker terminal) are a code violation. Each circuit must have its own dedicated breaker.
- Breaker labelling: Every circuit must be clearly labelled. Unlabelled panels make emergency shutoffs dangerous and can fail a Calgary Safety Codes inspection.
- Corrosion and moisture: Any sign of moisture intrusion or corrosion inside the panel enclosure requires immediate investigation. Water and electricity are a serious fire and electrocution hazard.
- Bus bar condition: The main bus bars must be free of discolouration, pitting, or signs of overheating. Burn marks on a bus bar indicate a past fault event that must be investigated.
- Panel clearance: The Alberta Electrical Safety Code requires a minimum of 1 metre of clear, unobstructed working space in front of all electrical panels. Storage in front of panels is a code violation and a safety hazard.
Wiring and Circuit Checks
After the panel, wiring is the next area commercial electrical inspectors examine in Calgary buildings. The focus is on safety, code compliance, and capacity.
- Wiring method: Commercial buildings in Calgary must use approved wiring methods — typically conduit (rigid, EMT, or flexible) rather than non-metallic sheathed cable, which is a residential product.
- Insulation condition: Wiring insulation must be intact with no cracking, chafing, or exposure. Damaged insulation is a fire and shock hazard.
- Circuit loading: Each circuit must not exceed 80% of its rated capacity under continuous load. Overloaded circuits cause nuisance breaker trips and accelerate insulation wear.
- GFCI protection: Ground fault circuit interrupter (GFCI) protection is required by the Alberta Electrical Safety Code in kitchens, bathrooms, janitorial rooms, outdoor outlets, and any wet or damp location.
- Junction box covers: All junction boxes must have covers in place. Open boxes expose wiring to damage and create a shock hazard for maintenance staff.
Many commercial electrical failures that result in fire or injury occur in buildings where electrical systems were never updated after original construction. In Calgary, many buildings dating from the 1970s and 1980s still have electrical systems that were not designed for today’s equipment loads.
Lighting and Emergency Systems
Emergency lighting and exit signage are life-safety systems. The City of Calgary and Alberta Electrical Safety Code set strict requirements for these components, and they are inspected during every commercial safety codes audit.
- Emergency lighting activation: Emergency lights must activate automatically within 10 seconds of a power failure. They must provide adequate illumination for safe egress for a minimum of 30 minutes.
- Exit sign operation: Exit signs must be illuminated continuously during business hours and must have battery backup to remain lit during a power outage. Burnt-out or dark exit signs are an immediate violation.
- Regular testing: The Alberta Fire Code requires monthly 30-second tests and annual 30-minute drain tests on all emergency lighting units. Maintain a written log of all tests.
- Commercial lighting systems: Lighting circuits must be sized correctly for the fixture load. Overloaded lighting circuits are a common problem in older Calgary retail and office spaces that have added LED retrofits without circuit review.
When to Call a Calgary Commercial Electrician
Some items on this checklist are safe for facility managers to check visually. Others must be assessed by a licensed Calgary commercial electrician. Call a professional immediately if you observe any of the following:
- Breakers that trip repeatedly on the same circuit
- A burning or warm smell near outlets, panels, or junction boxes
- Flickering or dimming lights under normal load
- Outlets or switches that feel warm to the touch
- Visible corrosion, burn marks, or discolouration inside any electrical enclosure
- Any panel that is unlabelled, overcrowded, or shows signs of past repair without a permit
These are not items to monitor over time — they indicate an active hazard that requires inspection before the next business day. Ampt Over Electric provides same-day and emergency commercial electrical inspections in Calgary and surrounding areas. Call 1 (368) 993-7463 to schedule.

Frequently Asked Questions
What is included in a commercial electrical inspection checklist?
A commercial electrical inspection checklist covers the main service panel, circuit breakers, branch circuit wiring, grounding and bonding, GFCI and AFCI protection, emergency lighting, exit signs, conduit integrity, outlet condition, and panel clearance. A licensed Calgary commercial electrician will also verify that all systems meet the Alberta Electrical Safety Code and City of Calgary permit requirements.
How long does a commercial electrical inspection take?
A standard commercial electrical inspection for a small-to-medium Calgary business takes 2 to 4 hours. Larger facilities — warehouses, multi-tenant buildings, or industrial sites — can take a full day or more. The inspection time depends on the size of the electrical system, the number of panels, and the age of the building.
Who can perform a commercial electrical inspection in Calgary?
In Calgary, commercial electrical inspections are performed by licensed journeyman or master electricians, or by a City of Calgary Safety Codes Officer. For routine audits between permit inspections, hire a licensed commercial electrician with experience in Alberta’s Safety Codes. Ampt Over Electric provides certified commercial electrical inspections throughout Calgary.
How much does a commercial electrical inspection cost in Calgary?
