GFCI Breaker keeps tripping

If you get an unbalance between the current going out on the hot wire and the current returning on the neutral wire, yes you can trip. How will unbalance in resistance between the hot wire and neutral wire cause a GF trip if these two wires are in series and should always see the same current unless there is true ground leakage current.

As for a 1 kw load, the GF breaker can always trip on overload but that is not the same as the GF button tripping.

 

Replace the outlet with a standard outlet and replace your circuit breaker with a GFCI breaker.

 

Make sure the face of the outlet is clean. Dirt or moisture can cause enough leakage to trip a GFCI. If it trips all by itself, and the face is clean and dry, replace the GFCI.

 

Mine is doing the same and I don’t have room to add a new line I only have 150amp box

I just replaced the gfci to see if it fixed it but nothing
What should I do?

 

call an electrician, but the least expensive way may very well be a sub panel. You can Google how they're used, if unfamiliar.
.

 

have you tried switching to 8 amp charging?

 

Yes

 

what all else is on that circuit?

 

Just Verizon box and outside outlets have a nest cam outside

 

It must be the birds trying to get a little privacy.

 

can you unplug them and see what happens?

 

Could be the charger going bad. Try a vacuum, or other high wattage appliance, plugged into the outlet to see if it trips...

 

Chances are is that the gfci is doing it's job.
Somehow there is current leakage back to ground instead of the current return.
The most probable way is where the extension cord has a connection in the outdoors.
There are two places this can happen.
1. In some portion of the cord it's self. A nick, a scratch, a tear in the cord
sheath, where it it can get sightly damp and touch the ground.
I had a cord that I used for many years for the Christmas lights that got touched by the weed wacker once too often.
It was a very small hole, but big enough to make the gfci unhappy.
The cord should be replaced.
2. at the outdoor plug side. If the cord end has been submerged ( or in contact with) in outdoor mud / slush it could be coated in a very slight conductive coating of salt ( not just the sodium kind ).
I've never been able to clean the connector (once it has faulted) so that it was good enough to remove all salts.
Once salts start conducting, other deposits can occur, especially with an electric charge.
Some deposits may be not water soluble, which makes it had to clean.
To avoid this only make electrical connections inside a chamber that does not come in contact with water, and ground (and its salts).
Sooo.. you need some way to make sure that the plug interface in the outdoors stays high and dry.
For my Christmas lights, I use a 2 liter soda bottle where I cut the top off.
I drove a ~14 inch wooden stake into the ground leaving 8 - 10 inches out of the ground.
Then I put the electrical connection into the bottle, and stuffed a rag in the bottle to keep the electrical connection at the bottom end of the bottle.
Push the bottle - connection - rag over the wooden stake so that it is upright and the electrical connection remains at the top inside of the bottle - high and dry.

Just my experiences...

 

GFCI outlets are know to fail. But if you're having the same problem with a replacement, I'd suspect that the problem is with whatever is plugged into the outlet -- in this case, your car's EVSE device.

(Of course, your replacement GFCI outlet could also be defective. I've actually experienced that happening on one occasion. Kinda like hitting the lottery twice.)

If you're using an extension cord, you should make sure that the cord and the connectors on both ends are clean, tight, and with no damage. If you're not using an extension cord, I seriously would suspect the EVSE device itself.

Does the GFCI trip when the EVSE is plugged in even if not connected to the car?
