Common questions

Electrical engineering questions for this scope.

What is included in service upgrade engineering?

Typical service upgrade support includes load calculations, service sizing, transformer adequacy review, one-line diagrams, meter/main layouts, equipment coordination, and permit drawings.

When is a transformer adequacy study useful?

A transformer adequacy review is useful when adding major load, EV charging, new tenant equipment, generator/ATS equipment, or upgraded service capacity.

Can you coordinate with the utility?

Utility coordination notes and utility-facing electrical documentation can be included. Ongoing coordination calls, applications, or site meetings can be added separately if needed.

What information is needed?

Useful inputs include existing utility service details, panel schedules, equipment nameplates, site photos, project load additions, service goals, and AHJ/utility requirements.
