Some wall-mounted EV chargers, like the EnelX JuiceBox series, offer both hardwire and plug-in options. A hardwired charger runs the electrical circuit directly to the device, while a plug-in device requires a 240 volt outlet to be installed. The charger is then wall-mounted and plugged into the outlet.
While a plug-in charger offers more flexibility since it can be removed, we recommend hardwire installation where possible since it is a safer, better looking, and more weatherproof option. Hardwire installations are also more reliable as they are less likely to “trip” and require reset.

Federal Pacific Electric (FPE) and Zinsco panels have design flaws that can cause their breakers to fail, creating a safety hazard.
Determine your electrical service by finding your main disconnect breaker. This is usually located on your main electrical panel or near your electric meter.
An electrician will place a new circuit breaker in your closest electrical panel and run wiring from the panel to the EV charger or outlet location.
