Common questions

Electrical engineering questions for this scope.

What EV charging projects are supported?

Support includes Level 2 and DC fast charging infrastructure for multifamily, commercial, fleet, workplace, and property-owner projects.

What electrical studies are often required for EV charging?

Common EV tasks include load studies, service capacity reviews, one-line diagrams, panel schedules, feeder sizing, load management coordination, and service upgrade planning.

Can EV charging be added to multifamily projects?

Yes. Multifamily EV infrastructure can be coordinated with house panels, site distribution, spare capacity, utility requirements, and phased charger installation strategies.

Does the scope include utility coordination?

Utility-facing documentation can be included, while extended utility application management or field meetings can be scoped separately if needed.
