We do not recommend doing so. There are many types of adapters on the market, and while some may appear to be NEMA 14-50R, their internal wiring may not be compatible with EV chargers, which can result in the charger not functioning properly. In addition, low-quality adapters with unreliable build quality may cause poor contact at the plug, leading to overheating and potentially causing the plug to burn or melt.

Yes, both the IYILO 48A Plug-in version and the IYILO 40A Plug-in version can be converted to a hardwired installation. You simply need to remove the NEMA 14-50 input cable and connect the hardwire input according to NEC code or your local electrical code. Please consult a licensed electrician for proper installation.

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.

The input cable of the IYILO Level 2 EV Charger is 37 inches long, which is suitable for most installation scenarios. The output cable is a 25-foot premium-grade cable that can fulfill most charging needs in driveways and garages.

An NTC plug is equipped with a temperature sensor at the charger’s input plug to monitor its temperature. When the plug temperature exceeds the safe range, the system sends an alert through the app and automatically reduces the current. If the temperature reaches a dangerous level, the charger will automatically shut off the power, and charging will resume once the temperature returns to a normal level.

The IYILO EV charger has a NEMA Type 4 enclosure, which means it is dustproof, rainproof, and suitable for outdoor use. However, this device should not be installed in outdoor locations with high corrosion levels, such as coastal areas.

The IYILO 48A Plug-in charger is factory preset for the NEMA 14-50 plug version. In compliance with NEC requirements, the maximum allowable current for the plug-in version is limited to 40A. If you wish to use the full 48A output, please switch to the hardwired version and use it with a 60A circuit breaker.
