Calgary process

For this scope, start by calculating the combined home and suite demand. A registered electrical contractor should confirm the current City application and inspection requirements.

ENMAX involvement

Where the work changes service equipment or requires an outage, confirm the current ENMAX intake and disconnect/reconnect procedure before scheduling.

What the quote should show

The written scope should distinguish contractor work, City fees/inspection, ENMAX or utility work, allowances, exclusions and closeout documentation.
