    What Is a 100A to 200A Upgrade?

    A 100A-to-200A proposal requires a load calculation and confirmation of the meter, service conductors, main disconnect and utility supply. A 200A panel enclosure alone does not establish 200A service.

    Compare panel-only replacement, additional distribution, load management and a utility service change. Have a qualified provider document the actual condition and accepted load calculation before selecting a path.

    Planning sequence

    1

    Document the property

    Record service rating evidence, panel condition, meter configuration and proposed loads.

    2

    Check feasible scope

    Request an accepted load calculation and address-specific utility connection requirements before choosing equipment.

    3

    Confirm hand-offs

    Identify the qualified permit holder, utility isolation, installation, inspection and reconnection responsibilities.

    4

    Close out

    Keep permit and inspection records, utility confirmation and a revised circuit schedule.

    Alberta Electrical Code & Permits

    Alberta code in force

    Alberta lists CSA C22.1-24 Canadian Electrical Code (26th edition) in force from April 1, 2025. Check https://www.alberta.ca/electrical-codes-and-standards for updates.

    Permit jurisdiction

    The Alberta Safety Codes system assigns accredited permit authorities by address. Confirm the actual authority before scheduling; see https://www.alberta.ca/permits-and-albertas-safety-code-system.

    ⚠️ Questions before deciding

    ✕Continued overloading causes wiring to heat and degrade, creating a fire risk
    ✕Insurance non-renewal or premium surcharges on undersized panels
    ✕For EV charging, compare the accepted load calculation with a dedicated circuit or listed load-management option
    ✕Cannot install central AC — modern units require 40–60A dedicated circuits
    ✕Failed home inspection at resale — buyers' lenders often require 200A service
    ✕Nuisance tripping causes power surges that damage appliances and electronics

    Local knowledge / Calgary, Alberta

    Calgary permits, capacity and project planning

    Calgary electrical permitting and ENMAX connection requirements are separate. A new enclosure does not confirm a larger approved supply. Keep the load calculation, permit scope and utility response together.

    Calgary homeowner permits exclude changes to the main electrical service, main panel, main breaker and meter base. Have the electrical contractor confirm the applicable permit and inspection sequence, and utility isolation or service review where required.
