EV Charger Load Calc
Breaker, panel & wire sizing
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Can the panel handle an EV charger? Check the load, then get breaker and wire size in seconds — made for electricians and EV installers.
The electrician's answer to one question: will this home panel handle an EV charger?
Pick NEC or IEC, choose the service rating (100/125/150/200/230 A presets or custom), enter the existing demand and the charger current (16/32/40/48 A or custom). The app applies the 125% continuous-load factor (NEC 625 / IEC 60364-7-722) and gives an instant verdict: FITS, CHECK or DOES NOT FIT — with service utilization, spare capacity and the largest charger the service takes without an upgrade. When it's tight or over, it points the way: load management (EVEMS) or a service upgrade.
