The Emporia Energy Level 2 EVSE EV Charger offers two installation methods: a pre-installed NEMA 14-50P plug or a pre-installed hardwire whip. Each option provides different benefits based on your needs and electrical setup.
NEMA 14-50P Plug/Outlet
Key Benefits:
Simple Installation: It plugs directly into existing NEMA 14-50 outlets
Charge Rate: Supports maximum continuous charge of 40A (per National Electric Code)
Flexibility: Easy to unplug and relocate if needed
Convertibility: Can be converted to a hardwire installation later if desired- Breaker Limitation: The maximum charging amperage using a 50A breaker with the NEMA plug is 40A, following NEC guidelines.
Hardwire Whip
Key Benefits:
Higher Charge Rate: Supports up to 48A with 60A+ breaker
Permanent Solution: Connects directly to the electrical panel or junction box via a dedicated line
Professional Installation: It is Recommended to hire a licensed electrician - Breaker Compatibility: The maximum supported amperage on a hardwired 60A breaker is 48A, as per National Electrical Code (NEC) standards. For smaller breakers, the charging rate must be configured accordingly.
Breaker Compatibility and Amperage Settings
Emporia chargers support various breaker sizes for different maximum charge rates. Users can configure the charger's amperage in the Emporia app to match their circuit capacity, ensuring safe operation. The system also adheres to NEC standards by optimizing charge rates based on each breaker type.
Choosing the Right Installation Option
Consider these factors when deciding between options:
Existing Setup: Using an existing NEMA 14-50 outlet is most cost-effective
Charging Needs: Some vehicles cannot utilize the full 48A of hardwired connections
Future Plans: NEMA plug offers easier relocation; hardwire is better for permanent installation
Local Codes: Always verify compliance with local electrical regulations.
App Configuration: The Emporia app allows users to set the charger's amperage based on their breaker size, ensuring compliance with NEC standards.
Additional Considerations
Installation Costs: A NEMA plug often has lower overall installation costs, especially with existing outlets
Durability: Hardwired installations eliminate wear from frequent plugging/unplugging
Future-Proofing: Hardwired setups may better accommodate future charging needs
