Course Review & EVITP Preparation

Key Concepts Review

  • Site assessment methodology and checklist (L1)
  • DOE Indian Energy and BIA DEMD tribal funding programs (L2)
  • SAE J3400/NACS connector standard; NEC Article 625 design principles (L3)
  • EVSE maintenance intervals: connector monthly, software quarterly, full audit annually (L4)

EVITP Exam Preparation
Focus your study on NEC Article 625 calculations (625.22 branch circuit sizing is the most tested topic), GFCI requirements (625.54), and the commissioning sequence. The practice questions below reflect actual exam difficulty — if you can answer these, you are well-prepared.

EVITP Certification Path

The Electric Vehicle Infrastructure Training Program (EVITP) is the national standard certification for EV charging station installation. Key facts:

  • Cost: $275 (initial) + $275 (renewal every 3 years)
  • Format: ~20 hours online, self-paced, 7 modules with knowledge checks
  • Exam: Proctored online; minimum 70% passing score required
  • Prerequisites: Any US state electrical license OR 8,000 hours documented electrical construction experience. California C-10 license not required for enrollment (but is required for CEC-funded CA installations).
  • Validity: 3 years from completion date
  • Exam fee assistance: Contact AMPS for information about exam fee assistance available for tribal members
EVITP vs. CA C-10 License
EVITP certification and the California C-10 Electrical Contractor license are separate credentials. EVITP accepts any US state electrical license for enrollment. The C-10 is a California state law requirement for CEC-funded installations in CA — it is separate from EVITP. You may need both depending on your role.

EVITP-Style Practice Questions

The following questions reflect EVITP exam topics. Test yourself before the real exam.

  1. Under NEC 625.22, a branch circuit supplying a 40A continuous-load EVSE must be rated at minimum:
    (a) 40A   (b) 45A   (c) 50A   (d) 60A
    Answer: (c) 50A. Calculation: 40A × 1.25 = 50A. All EVSE are continuous loads by definition.

  2. NEC 625.54 requires GFCI protection for EVSE installed in which location?
    (a) Indoor office only   (b) Garage only   (c) Outdoor only   (d) Outdoor, garage, and carport locations
    Answer: (d). NEC 625.54 covers outdoor installations and areas accessible from the exterior including garages and carports.

  3. A 7.2 kW Level 2 EVSE operates at 240V. What is the EVSE's operating current draw?
    (a) 24A   (b) 30A   (c) 36A   (d) 40A
    Answer: (b) 30A. Calculation: 7,200W ÷ 240V = 30A.

  4. The branch circuit for the 7.2 kW EVSE above must be sized at minimum:
    (a) 30A   (b) 35A   (c) 37.5A → use 40A breaker/conductor   (d) 50A
    Answer: (c) 37.5A minimum, rounded up to 40A. Use 8 AWG copper on 40A double-pole breaker.

  5. True or False: EVITP certification requires a California C-10 Electrical Contractor license specifically.
    False. EVITP accepts any US state electrical license. The CA C-10 is a California state law requirement for CEC-funded installations in CA — it is separate from EVITP enrollment.

  6. Which NEC article governs EV charging equipment installation?
    (a) Article 210   (b) Article 220   (c) Article 625   (d) Article 705
    Answer: (c) Article 625. Articles 210 and 220 cover branch circuits and load calculations generally; 705 covers interconnected power production equipment.

  7. The EVITP exam requires a minimum passing score of:
    (a) 60%   (b) 65%   (c) 70%   (d) 80%
    Answer: (c) 70%.

  8. EVITP certification is valid for how many years?
    (a) 1   (b) 2   (c) 3   (d) 5
    Answer: (c) 3 years. Recertification requires completing the latest course version and passing the exam again ($275).

  9. V2G technology (Vehicle-to-Grid) is covered in EVITP Module:
    (a) 3   (b) 4   (c) 5   (d) 6
    Answer: (c) Module 5: Bi-directional Chargers and Microgrid.

  10. A GFCI trips repeatedly on an outdoor EVSE circuit. The correct action is:
    (a) Replace the GFCI   (b) Use a higher-rated breaker   (c) Investigate for a ground fault before resetting   (d) Bypass the GFCI
    Answer: (c). Repeated GFCI trips indicate a real ground fault condition. Never bypass a GFCI to restore service.

  11. True or False: A Level 2 EVSE connector follows the SAE J1772 standard for AC charging; SAE J3400/NACS is used for both AC and DC fast charging.
    False. SAE J1772 is Level 1/2 AC only. SAE J3400/NACS (standardized 2023) is used primarily for DC fast charging. CCS Combo (CCS = Combined Charging System) is the standard for DCFC on non-Tesla vehicles.

  12. You are commissioning a Level 2 EVSE installation. Arrange these steps in correct order:
    (A) Activate EVSE and register with network; (B) Perform insulation resistance test (megger); (C) Verify all wiring per drawings; (D) Test with known-good vehicle; (E) Final inspection and CEC documentation
    Correct order: C → B → (energize) → D → E
    Explanation: Verify wiring first, test insulation before energizing to avoid damage, energize, test charging, then document for grant compliance.

  13. A 9.6 kW Level 2 EVSE operates at 240V. Under NEC 625.22, the branch circuit must be sized at minimum:
    (a) 40A   (b) 45A   (c) 50A   (d) 60A
    Answer: (c) 50A. Calculation: 9.6 kW ÷ 240V = 40A EVSE current. 40A × 1.25 = 50A minimum circuit. Use 6 AWG copper on 50A double-pole breaker.

  14. After installing an EVSE, you run a test with a known-good vehicle but the charging session will not initiate. Which is the FIRST troubleshooting step?
    (a) Check network connectivity in the cloud   (b) Verify correct voltage at EVSE line terminals   (c) Perform insulation resistance test (megger) on the circuit   (d) Replace the EVSE unit
    Answer: (b). Before assuming the EVSE or network is faulty, verify the electrical foundation is sound — confirm proper voltage is present at the EVSE terminals. This rules out upstream wiring or breaker issues before further diagnostics.

  15. An AMPS site needs to charge 4 electric vans overnight (each 7.2 kW EVSE at 240V). The utility offers off-peak rates of $0.12/kWh (9 PM–6 AM) and peak rates of $0.30/kWh (6 AM–9 PM). What is the cost difference per van per night between off-peak and peak charging?
    (Assume each van draws 7.2 kWh per night)
    (a) $0.86   (b) $1.16   (c) $1.30   (d) $2.16
    Answer: (c) $1.30 per van per night. Off-peak: 7.2 kWh × $0.12 = $0.86. Peak: 7.2 kWh × $0.30 = $2.16. Difference: $2.16 − $0.86 = $1.30. This reinforces why AMPS depot charging should target TOU off-peak windows.
