Because ground fault protection is to protect against ground faults, not overloads.
OP. since you had to ask, get an electrician.
Because ground fault protection is to protect against ground faults, not overloads.For what it's worth, my garage has a GFCI outlet (and the EVSE has one also) yet when I accidentally overloaded the circuit by running a shop vac while my car was plugged in, it tripped the breaker not the ground fault protection.
And filling out forms for any state and federal EVSE rebates/tax credits.From the description it seems that there are serious electrical shortcuts in this garage already.
- Nothing else should be on the lighting circuit especially a garage door opener. If the breaker trips it will not only stop working, you will be in the dark.
- An EVSE needs it's own dedicated 20-amp (minimum) circuit.
So a couple things need to happen:
1. Hire an electrician.
2. Electrician to assess the work needed.
3. Work to include a dedicated circuit for the EVSE.
4. Work to include a circuit for the garage door opener.
5. Work to include a circuit or circuits for general use.
6. Lighting assessment for safety and adequate lumens.
7. All work complies with local permitting and standards.
8. Home owner work is limited to writing the check.
