The symptoms are that the JuiceBox/Cord begins charging the EV, but charge is disrupted by clicking on and/or off sound or it may stop. (Your JuiceNet Dashboard may display "GFI tripped" during these interrupt events, or just "Error").
This is because your JuiceBox is cycling on and off in response to Ground Fault Interrupt instances. This could be due to a legitimate reason, such as water in your charge cable or EV charge port, an incision or fray in your wiring), or an obstacle in the way of your charge plug. If this is a newly occurring issue, it may be the result of some kind of environmental damage. Check your entire charge circuit (from EV to breaker box). It may be that the charge cable has been twisted out of place by repeated movement. Try twisting the charge cable as it enters the JuiceBox unit. Also check the cable handle for particularities in the top button,.
If this issue has occurred since you had the unit installed, check your installation. It may be worth having an electrician check the wiring all the way back to the distribution box.
