EVITP Electrical Safety and Codes

Question 1

What is arc flash risk during EV charger work?

Accepted Answer

Explosive energy release from electrical fault causing burns and death

Answer

Arc flash produces extreme heat and pressure from an electrical fault.

Question 2

What PPE is needed for energized EV charging work?

Accepted Answer

Arc-rated clothing, insulated gloves, safety glasses, voltage-rated tools

Answer

Multiple layers of electrical-specific protection are required.

Question 3

What is lockout/tagout for EV installations?

Accepted Answer

Ensuring circuits are de-energized and locked to prevent accidental energization

Answer

LOTO physically prevents power from being restored during maintenance.

Question 4

What is a GFCI and why is it required for EV charging?

Accepted Answer

Detects ground faults and disconnects power to prevent shock

Answer

GFCI protection detects current leakage and disconnects in milliseconds.

Question 5

What wire sizing factors apply to EV charging?

Accepted Answer

Continuous load rating, voltage drop, ambient temperature, conduit fill

Answer

Multiple factors beyond just current draw affect wire sizing.
