Proper placement can make everyday charging easier and reduce the need for extension cords or inconvenient cable routing.
8. Check Whether Your Electrical Panel Needs an Upgrade
Not every Phoenix home needs a panel upgrade to install an EV charger.
However, an upgrade may be considered when:
- The existing panel has insufficient capacity
- The panel has limited breaker space
- The home’s electrical load is already high
- The panel is outdated or damaged
- Additional electrical equipment is planned
A 200 amp electrical panel may provide additional capacity for some homes, but the correct service size should be determined through an electrical load evaluation.
9. Consider Future Electrical Needs
When installing an EV charger, think beyond your current vehicle.
You may eventually add:
- A second EV
- Additional HVAC equipment
- Solar equipment
- Pool equipment
