EV Charger Not Charging at Home in Loganville, GA
If your EV charger powers up but fails when the vehicle starts charging, the problem may be in the charger, the breaker, the wiring, the grounding path, or even the vehicle itself. Kais Pro Repairs diagnoses the issue properly instead of guessing.
When an EV charger fails only after the car connects, there is usually a real fault behind it
A charger that sits green and healthy until the vehicle begins charging is telling you something important. The equipment is getting power, but the charging sequence is detecting a problem once load is applied.
That can point to a ground fault issue, a wiring problem, a poor breaker connection, a charger fault, or a vehicle-side problem. Replacing random parts without testing wastes time and money. The right move is to test the system in order.
- Verify voltage at the breaker and charger terminals
- Inspect the grounding path and panel termination quality
- Check for signs of heat, loose lugs, or improper breaker connection
- Compare charger behavior with different vehicles or charging sources when possible
- Determine whether the fault is house-side or vehicle-side
Common causes of EV charger faults at home
- Improper termination at breaker or charger lugs
- Damaged cable or insulation issues
- Ground fault detection during charge startup
- Incorrect breaker sizing or hardware issues
- Panel problems affecting stable charging voltage
- Vehicle charging fault that shows up on multiple chargers
What we look at when your EV charger is not charging at home
EV charging faults need a structured diagnosis. This is not a guess-and-swap service call.
Panel and breaker inspection
We inspect the breaker, wire terminations, grounding, and overall panel condition. A charger can power up normally and still fail once charging current begins.
Charger wiring verification
We verify that the conductors are landed correctly and that the charger is set up according to the manufacturer’s requirements for that model.
Fault behavior review
We look at exactly when the fault occurs. Green to blue to red, immediate trip, delayed failure, and repeated reset behavior all point in different directions.
Load and performance testing
Once load is introduced, hidden issues show themselves. That is often when imbalance, voltage problems, overheating, or nuisance trip conditions appear.
Vehicle-versus-home diagnosis
If the same vehicle also has problems on other chargers or on the portable charger, the problem may not be the home installation at all.
Clear next-step recommendation
We explain whether the fix is in the charger, wiring, breaker, panel, or whether the owner may need vehicle-side service.

Frequently asked questions about EV charger problems
Why is my EV charger turning green, then blue, then flashing red?
That usually means the charger powers up normally, sees the vehicle connection, then detects a fault after the charging sequence begins. That can be caused by wiring issues, grounding problems, a bad breaker connection, charger faults, or a vehicle-side charging issue.
Can the problem be in the car instead of the charger?
Yes. If the car also fails to charge on a public charger or on the portable charger that came with the vehicle, the issue may be on the vehicle side rather than in the home installation.
Do all Level 2 EV chargers need a neutral wire?
No. Many Level 2 chargers use two hot conductors and an equipment ground, with no neutral connected. The exact wiring still depends on the charger model and manufacturer instructions.
Can a bad breaker cause EV charging issues even if the charger turns on?
Yes. A charger may power up at idle but fail once the vehicle starts drawing current. Loose terminations, weak breaker connections, overheating, or incorrect hardware can all create charging problems under load.
