What Is a 200A to 400A Upgrade?
A 400A request may change metering, service conductors and distribution configuration. Ask the utility whether its equipment can serve the proposed demand before committing to an enclosure.
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.

Local knowledge / Calgary, Alberta
A larger rating needs a coordinated service review
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.
