EVITP Infrastructure Planning and Development 2

Question 1

When performing a site assessment for EVSE installation, which utility document is most critical to obtain first?

Accepted Answer

Existing service entrance capacity report

Answer

The existing service entrance capacity report determines whether the utility can support added EV load without costly upgrades.

Question 2

A parking facility wants to install Level 2 EVSE in 20% of spaces as required by a local ordinance. Which planning step ensures future scalability?

Accepted Answer

Running conduit sleeves to all spaces but wiring only the required 20%

Answer

Make-ready infrastructure—conduit without wiring—allows cost-effective future expansion without tearing up pavement.

Question 3

Under the ADA, what is the minimum number of accessible EV charging spaces required when a facility installs 10 total EVSE spaces?

Accepted Answer

1

Answer

ADA guidelines specify at least 1 accessible EV charging space for every 1–25 total EV spaces provided.

Question 4

Which load management strategy is best suited for a multi-tenant commercial building seeking to add EVSE without upgrading the utility transformer?

Accepted Answer

Dynamic load management software that throttles charging based on building demand

Answer

Dynamic load management allocates available amperage across chargers in real time, preventing transformer overload.

Question 5

A project in a coastal region requires EVSE rated for a wet, salt-air environment. What minimum NEMA enclosure rating applies to the charger cabinet?

Accepted Answer

NEMA 4X

Answer

NEMA 4X provides protection against corrosion, windblown dust, and hose-directed water, making it suitable for coastal salt-air environments.
