Why Choose Square D Breakers?
If you’re sourcing reliable, CSA-approved circuit protection equipment in Alberta, Square D breakers stand out for unmatched safety, performance, and long-term durability. Whether you’re upgrading a residential panel in Calgary or maintaining a commercial facility in Edmonton, choosing a trusted brand like Square D—crafted by Schneider Electric—ensures your system meets Canadian Electrical Code standards without compromise.
Reliability and Durability
Square D breakers are engineered by Schneider Electric, a global leader in energy management and automation. Their time-tested quality and sturdy design provide consistent protection against electrical faults, surges, and overloads. With thermal-magnetic trip mechanisms and robust housing materials, each breaker is built to perform in harsh Canadian climates, from Calgary winters to coastal humidity in B.C. That level of reliability is why facility managers and electricians across Alberta turn to Square D for both new installations and breaker replacements.
Compatibility with Canadian Electrical Standards
Every Square D breaker we distribute is CSA approved, meaning it’s fully compliant with the Canadian Safety Standard C22.2. These breakers integrate seamlessly with a wide range of load centers and panels commonly used across the province. Whether you’re working on a residential retrofit or a large-scale commercial upgrade, you can count on Square D to fit right the first time—no guesswork, no rewiring. A local Calgary contractor recently mentioned, “Alberta Breaker makes it easy to stay code-compliant with Square D. I can get exactly what I need, fast.”
Choose equipment that’s engineered for Canada—because when power protection matters, Square D delivers peace of mind.

Not all breakers are created equal—and at Alberta Breaker & Supply Co Ltd, we help you choose the ideal Square D model for every application. From residential renovations to commercial new builds, understanding the available breaker types can save you time, enhance safety, and ensure seamless installation in any panel configuration.
Single Pole vs Double Pole Breakers
Single pole breakers are the most common solution for residential applications. With a 120V rating, they control individual lighting circuits, outlets, and small appliances. Ideal for standard Calgary homes or DIY upgrades by homeowners, these models balance affordability and function.
Double pole breakers, on the other hand, handle 240V loads and are essential for high-draw appliances like electric stoves, dryers, and HVAC systems. These are vital for contractors wiring new homes or facility managers maintaining commercial systems in Alberta. Square D’s precision engineering ensures proper overload protection in both single and multi-phase installations.
AFCI and GFCI Safety Features
Advanced protection has become a legal and functional necessity. AFCI (Arc Fault Circuit Interrupter) breakers detect dangerous arcing caused by damaged or deteriorating wires—often before visible damage occurs—and are required in many living areas under current Canadian code. GFCI (Ground Fault Circuit Interrupter) models prevent shocks in wet environments like bathrooms, kitchens, and exterior outlets.
Alberta Breaker carries a full range of AFCI, GFCI, and combination models pre-labeled and ready for code-compliant installation. As one Calgary electrician put it, “These ready-to-ship units save me hours. I don’t have to second-guess compatibility.”
Explore the right type of Square D breaker to meet your exact needs—residential or commercial, code-compliant and ready to ship across Canada.
Electrical Code Compliance in Alberta
A certified electrician reviews a Square D breaker panel, ensuring safety and compliance at an Alberta location.
In Alberta, safety is more than a recommendation—it’s the law. Choosing breakers that comply with the Canadian Electrical Code (CEC) and local Alberta Building Code is essential whether you’re an electrician, project manager, or homeowner. At Alberta Breaker & Supply Co Ltd, we only stock CSA-approved Square D breakers that meet or exceed all provincial inspection standards. That means you’re always code-ready, from Calgary to Cold Lake.
Understanding Alberta Building Code and Canadian Electrical Code
Electrical systems in Alberta must pass inspections governed by the Canadian Electrical Code (Part I) as adopted by Alberta Safety Codes Council. These codes dictate everything from breaker sizing and panel compatibility to AFCI/GFCI usage in specific zones. Violations could result in inspection delays, insurance issues, and safety hazards. Square D products simplify this process by offering certified solutions that align with national and provincial mandates, including critical residential safety updates required in new construction permits.
Are Square D Breakers CSA Approved?
Yes. Every single Square D breaker sold at Alberta Breaker is CSA certified at the manufacturing level. This means the product has passed rigorous testing to meet Canadian operating conditions and electrical performance requirements. Look for the CSA mark alongside detailed amp ratings and serial identifications, giving peace of mind to professionals and inspectors alike.
Working with a Licensed Electrician in Calgary or Edmonton
While Square D breakers are designed for user-friendly installation, working with a licensed electrician ensures full compliance and long-term safety. Whether you’re replacing a load center in Edmonton or upgrading a smart panel in Calgary, electricians trained in Alberta code will maximize the performance of your system. We regularly supply local contractors with authorized Square D components, backed by advice from our in-house technical team.

Commercial vs Residential Use of Square D Breakers
Not all Square D breakers are created equal—and choosing the right one starts with understanding where it’s being used. Whether you’re outfitting a new home panel or upgrading an industrial electrical room, selecting the right model ensures code compliance, optimal panel lifespan, and overall safety. Below, we break down the practical differences between residential and commercial Square D applications for buyers across Calgary, Edmonton, and Canada-wide.
Residential Applications: Panels, Kitchens, Garages
Square D’s QO™ and HOM™ series breakers are the go-to solutions for single-family homes and small-scale dwellings. They support kitchens, bedrooms, garages, and appliance circuits with seamless plug-on installation and budget-friendly safety features like AFCI and GFCI. Available amp ratings typically range from 15A to 60A, tailored to home use. Homeowners and renovators often benefit from Square D’s modern panel upgrades that support breaker-neutral connectivity without pigtails—faster installs, neater layouts.
Commercial Use: Light Industrial and Facility Use
In commercial settings—warehouses, hospitals, schools—Square D breakers must handle higher loads and industrial-grade trip mechanisms. These include three-phase solutions, bolt-on breakers, and panelboards that accommodate specialized enclosures. Commercial Square D panels often require custom configurations based on facility voltage and amperage draw. For Alberta-based facility managers, Alberta Breaker stocks a wide variety of Square D commercial breaker models with detailed specs for your specific use.
Selecting the Right Amp Rating and Trip Protection
Understanding your circuit’s load and protection requirements is key. From simple 15A residential circuits to 100A commercial three-phase setups, Square D offers appropriate breakers built to protect your circuits from overloads and faults. When in doubt, our shop specialists assess compatibility with your panelboard and applicable code standards.
Always check breaker compatibility with your panel’s specifications before installation.
