The Benefits of Hardwiring a Level 2 EV Charger
When it comes to installing an electric vehicle (EV) charging station at your home or business, making the right choice can have a significant impact on charging speeds, installation costs, and overall longevity.
COIL, the industry leader in EV charging solutions, highly recommends hardwiring a Level 2 charger over using NEMA 14-50 outlets and Ground Fault Circuit Interrupter (GFCI) breakers
Why COIL Recommends Hardwiring:
Stability
Hardwiring provides a more stable connection
Longevity
No wear and tear from plugging and unplugging a unit from an outlet for an increased lifespan
Durability
EV Charger is securely mounted to the wall and protected from external factors for enhanced durability
Similar Costs
Similar cost for hardwiring to NEMA outlet installation
What's Nuisance Tripping?
Most EV chargers have internal ground fault circuit interrupter (GFCI) protection so the breaker in the main panel will shut off (or “trip”) if there is a surge in the system. However, electrical codes require a GFCI breaker for NEMA outlets in residential homes as a safety precaution as well. This double layer of GFCI protection can cause nuisance tripping and prevent EV charging.
