Arc flash studies in Calgary

CCT 01Start with the right decision

An arc flash assessment relies on the actual distribution system, protective devices and operating conditions. Outdated drawings and assumed settings can undermine the result. Define the study boundary and data-collection work before comparing prices. Short-circuit, coordination and arc flash analyses answer related but different questions.

CCT 02What to put in the scope

Use this as a discussion checklist. The contract should assign each item to a named party and identify anything excluded. Ask for unclear existing conditions to be investigated before they become assumptions in a fixed price.

CCT 03Who needs to coordinate

The owner provides records and access; qualified personnel gather equipment information; the responsible specialist develops and reviews the model. The electrical safety program remains an employer responsibility. A label alone does not authorize energized work or define every precaution for a task.

CCT 04A practical project sequence

Agree the equipment list, operating modes and study method. Resolve missing data and record assumptions. Review recommendations before changing protective settings. Update drawings and labels to match the accepted final configuration and retain the model for future changes.

Read the Commercial electrical permits in Calgary and ENMAX commercial service connections guides when planning approvals and service changes.

CCT 05What changes the price

Equipment count, inaccessible data, shutdown requirements and model complexity drive cost. Ask whether the proposal includes site collection, utility coordination, editable model files and a revision after implementation. Avoid treating an old study as current after distribution changes.

Continue with Arc flash study & thermography cost and the Comparing electrical bids checklist. Compare like-for-like scope before comparing totals.

CCT 06Calgary requirements and safety

• OHS Code Part 15 (Managing the Control of Hazardous Energy) requires hazardous energy to be isolated with a secured energy-isolating device before equipment is serviced, repaired, tested, adjusted or inspected. ¹
• The 2024 Canadian Electrical Code, Part I (CSA C22.1-24, 26th edition) is the electrical code in force in Alberta, declared in force on April 1, 2025. ²

These pages concern Calgary. Confirm the authority and wire-service provider for Airdrie, Rocky View County or another neighbouring municipality. The applicable permits and connection process may differ.

CCT 07What the owner should receive

Keep the report, model ownership terms, assumptions, drawings and implemented settings together. Establish a review process when equipment, supply or operating configurations change.

Keep proposed work, accepted changes, inspection evidence and remaining deficiencies together. A verbal assurance is difficult for the next property manager or maintenance contractor to use.

CCT 08Apply the scope to your building

Industrial & manufacturing · Data centres & server rooms · Property & facility management

Select the industry guide for its equipment, access and operating considerations. The electrical scope should reflect the actual business and building, not simply its floor area.
