EV Charger Voltage Drop
Voltage Drop for EV Charger Installations
EV chargers are continuous loads that often require long circuit runs, making voltage drop a critical design consideration.
Key Points
- • Level 2 chargers draw 40-80A continuously for hours
- • Calculate at 125% of rated current per NEC 625.40
- • Excessive voltage drop reduces charging power
