Every sector buys electrical work differently

A restaurant needs three-phase kitchen power and a fast turnover; a condo board needs a capacity study before a single charger; a warehouse is won or lost on lighting hours. Open a section.

Sequence of work

The path from scope to energized

Most commercial electrical delays trace to a step taken out of order: a service application sent late, drawings missing at permit, an inspection booked before the work was ready. Here is the order Calgary projects follow.

  1. Load & scopeWhat the building has, what it needs, and whether the service can carry it.Capacity →
  2. Design & drawingsDrawings go with the permit for new construction and service upgrades of 600 A and higher1.Engineer or contractor →
  3. Utility applicationServices over 200 A are CT-metered and need ENMAX’s CT request and checklist2.ENMAX →
  4. PermitsBase-building work and each tenant space take separate electrical permits1.Permits →
  5. Rough-in & inspectionsWork is inspected by the City in stages; failed inspections cost a re-inspection fee and time.TI process →
  6. EnergizationA new or upgraded site must pass inspection before ENMAX energizes it2.Service upgrades →
  7. Life safety & occupancyFire alarm systems are verified to CAN/ULC-S537 under the Alberta building code3.Life safety →
  8. Operate & maintainAnnual inspections, preventive maintenance and an annual electrical permit for ongoing facility work.Maintenance →
