Frequently asked questions

In the NEMA 14-50 plug-in version, the IYILO charger supports a maximum current of 40A and a maximum power output of 9.6 kW.

For the NEMA 14-50 plug-in version, the maximum current (Dip switch setting) is preset to 40A at the factory. According to NEC (National Electrical Code) guidelines, the circuit breaker should be rated at 125% of the continuous load. Therefore, a 50A breaker should be used.

The preset current for the 48A/40A Plug-in version is 40A, while the preset current for the 48A Hardwired version is 48A.

According to the NEC code, a 48A charger requires a 60A circuit breaker.

The default current is 40A (RA40) and 48A (RA48). You can adjust the current in 1A increments via the IYILO App.If you want to switch between a 48A hardwired installation and a 40A plug-in setup, you can do so by adjusting the internal rotary switch, which allows you to toggle the maximum current.

All versions of the IYILO EV Charger include a built-in GFCI Protection for personnel protection. According to NEC code, NEMA 14-50 outlets must have GFCI breaker. However, our charger performs a self-test that generates a small ground fault, which may cause external GFCI breakers to trip and interrupt charging. If local regulations require GFCI protection on the outlet, we recommend using a hardwired installation instead.

If you purchased the NEMA 14-50 plug-in version of the EV charger and already have a compatible outlet and circuit breaker installed, simply mount the charger on the wall and plug it into the outlet—no additional electrical work is needed.

If you are installing the hardwired version of the charger, we recommend hiring a certified electrician to complete the installation.

To upgrade the 48A plug-in charger to a hardwired version, you will need to replace the NEMA 14-50P input cable with a hardwired connection.You will need to prepare the following components yourself: L1, L2, and GND wiring (rated to support 48A current, we recommend using 6 AWG wires) and a 1″ liquid-tight conduit.For your convenience, we’ve included an AD34.5 conduit fitting inside the product package to assist you during the conversion process.

Please note: The 48A NEMA 14-50 plug version is factory preset to a 40A current limit.When converting it to the 48A hardwired version, please make sure to turn the rotary switch on the mainboard to any position between 3 and 9 to ensure the current limit is updated to 48A after the conversion.
