EVITP Final Actual Exam and Practice Tests

Detailed Answers| Brand New Version
Section 1: Safety & PPE (Questions 1-15)
1. What is the minimum arc flash rating (cal/cm²) required for PPE when
performing live voltage testing on a Level 2 EVSE rated at 80A?
a) 0 cal/cm² (Cotton clothing only)
b) 4 cal/cm²
c) 40 cal/cm²
d) 100 cal/cm²
Rationale: EVITP emphasizes that while EVSEs are often "dead front," when
working inside enclosures with potential fault currents exceeding 10kA (common
for 80A circuits), an arc flash hazard exists. Category 4 PPE (40 cal/cm²) is
required for many commercial/residential installations to protect against arc
flash burns.
2. Before beginning any installation involving the disconnection of an existing
service panel, the first step is to:
a) Remove the meter socket cover.
b) Contact the utility provider to secure the service or install a lockout/tagout.
c) Turn off the main breaker and assume the panel is dead.
d) Verify the presence of a grounding electrode system.
Rationale: EVITP mandates strict Lockout/Tagout (LOTO) procedures. Unlike
standard electrical work, EVSE installations often require coordination with the
utility to ensure the service drop is de-energized or to verify that unauthorized
re-energization cannot occur while modifying service conductors.
,3. When using a multimeter to verify zero voltage on a 480V 3-phase EVSE
supply, what is the correct safety protocol?
a) Use a non-contact voltage tester only.
b) Set the meter to "Ohms" to test continuity.
c) Wear rubber insulating gloves with leather protectors and follow a "test
before, test after" procedure on a known live source.
d) Short the terminals to ground with a screwdriver after turning off the breaker.
Rationale: EVITP stresses the "Live-Dead-Live" test method. Rubber insulating
gloves are required for voltages above 50V to prevent shock. Testing a known live
source before and after verifying the dead circuit ensures the meter is
functioning correctly.
4. A Level 3 DC Fast Charger (DCFC) cabinet is being installed. What is the
primary safety risk specific to this equipment that differs from Level 2 AC?
a) High amperage AC shock
b) High voltage DC (up to 1000V DC) stored in capacitors
c) Refrigerant leaks from cooling systems
d) Electromagnetic interference with pacemakers
Rationale: DCFC units contain high-voltage DC bus capacitors that remain
charged even after the AC supply is disconnected. EVITP training highlights the
need to wait for the "bleed-off" time (often 5-10 minutes) or use a ground stick
to discharge these capacitors before servicing.
5. What does "NFPA 70E" primarily govern in the context of EVSE installation?
a) The color of the EVSE housing
b) Electrical safety in the workplace, including arc flash and shock protection
c) Wiring methods for parking lots
d) Utility metering standards
Rationale: NFPA 70E (Standard for Electrical Safety in the Workplace) is the
,cornerstone standard for electrical safety. EVITP requires installers to understand
70E requirements for PPE, boundaries, and safe work practices, not just the NEC
(NFPA 70).
6. When lifting a heavy DCFC power cabinet (500+ lbs), EVITP safety guidelines
require:
a) One technician using a dolly.
b) Use of mechanical lifting equipment (forklift or crane) with certified rigging.
c) Disconnecting the battery backup first.
d) Lifting only by the conduit hubs.
Rationale: Heavy EVSE components require engineered lifting plans. EVITP
emphasizes that improper lifting can cause fatal crushing injuries or damage to
the sensitive electronics within the cabinet. Mechanical aids are mandatory for
heavy equipment.
7. What is the purpose of a "Ground Fault Circuit Interrupter" (GFCI) protection
on a Level 2 EVSE circuit?
a) To protect the vehicle's battery from overcharging.
b) To protect the equipment from lightning strikes.
c) To protect personnel from electric shock by opening the circuit if current
leaks to ground.
d) To monitor the communication signal between the car and charger.
Rationale: EVITP differentiates between GFCI (personnel protection) and
equipment ground fault protection. For EVSE outlets (like NEMA 14-50), GFCI
protection is required by the NEC to prevent electrocution hazards in wet
locations like garages.
8. Before drilling into a concrete parking structure for conduit attachment, the
installer must:
a) Use a hammer drill with no vacuum.
, b) Verify the location of post-tension cables via X-ray or ground penetrating
radar.
c) Drill only during daylight hours.
d) Ensure the parking spaces are occupied.
Rationale: EVITP highlights the extreme danger of cutting post-tension cables in
concrete slabs. Severing a cable can cause catastrophic structural failure, violent
release of energy, and severe injury or death.
9. Regarding fire extinguishers on a commercial EVSE job site, what type is
required for electrical fires?
a) Class A (Water)
b) Class B (Foam)
c) Class C (Non-conductive dry chemical or CO2)
d) Class D (Metal)
Rationale: Class C fire extinguishers are rated for energized electrical equipment.
Using water (Class A) on live EVSE equipment poses a severe shock hazard to the
firefighter or technician.
10. During a vehicle-to-grid (V2G) installation, what unique safety condition
exists regarding the grid connection?
a) The vehicle engine must be running.
b) The system must have a Listed microgrid interconnect device or automatic
transfer switch to prevent backfeeding the grid during outages.
c) The voltage is reduced to 12V.
d) No grounding is required.
Rationale: V2G (bidirectional charging) turns the EV into a generator. EVITP
stresses that without a proper transfer switch or Listed interconnect device,
backfeeding the grid creates a life-threatening hazard for utility line workers.
