EVITP Electrical Safety and Codes 2 — Questions and Answers
Question 1: What testing is needed after EV charger installation?
- Voltage verification, ground continuity, GFCI test, functional charge test (Correct answer)
- Just plug in and check
- Only check voltage
- Visual inspection only
Correct answer: Voltage verification, ground continuity, GFCI test, functional charge test
Multiple tests for electrical safety and functionality are required.
Question 2: What are outdoor EV charger installation requirements?
- Weather-rated enclosures, proper drainage, GFCI, weather-resistant conduit (Correct answer)
- No special requirements
- Only a roof
- Standard indoor equipment works
Correct answer: Weather-rated enclosures, proper drainage, GFCI, weather-resistant conduit
Outdoor installations need specific weather protection.
Question 3: What is electrical bonding for EV chargers?
- Connecting all metal parts to same electrical potential to prevent shock (Correct answer)
- Gluing wires together
- Wire insulation type
- Connecting terminals
Correct answer: Connecting all metal parts to same electrical potential to prevent shock
Bonding prevents dangerous voltage differences between metal parts.
Question 4: What ADA requirements apply to EV charger installations?
- Accessible route, reach ranges, maneuvering space, signage (Correct answer)
- No ADA requirements
- Only ramps
- Only for indoor chargers
Correct answer: Accessible route, reach ranges, maneuvering space, signage
Accessibility standards ensure all people can use charging equipment.
Question 5: What trenching requirements apply to underground conduit?
- Minimum burial depth per NEC, sand bedding, warning tape (Correct answer)
- Any depth works
- No burial requirements
- Only 2 inches deep
Correct answer: Minimum burial depth per NEC, sand bedding, warning tape
Underground conduit has specific depth and protection requirements.
Question 6: What utility coordination is needed for commercial EV charging?
- Notify about demand increase, potential upgrades, rate options (Correct answer)
- No coordination needed
- Just file a permit
- Only pay the bill
Correct answer: Notify about demand increase, potential upgrades, rate options
The utility needs to know about significant new electrical loads.
