EV charger wiring is one of the most important parts of the installation, even though it’s usually the part homeowners never see.
A Level 2 EV charger can draw substantial electrical current for an extended period, so the wiring, breaker, connections, and electrical panel all need to be appropriate for the equipment.
If you’re planning an EV charger installation in Orlando, here’s what you should know about the wiring involved.
Why EV Charger Wiring Matters
EV charging isn’t the same as plugging in a small household appliance for a few minutes.
A charger may operate for several hours while your vehicle is parked, creating a sustained electrical load.
The wiring needs to be appropriately sized for the charger’s requirements and installed according to applicable electrical standards.
Using inadequate wiring can create overheating and other electrical hazards.
What Determines the Wiring Size?
The required wire size depends on the electrical characteristics of the charger and the installation.
Factors can include:
- Charger amperage
- Circuit rating
- Voltage
- Installation method
- Distance from the electrical panel
- Wiring route
- Applicable electrical requirements
Your electrician can determine the appropriate wiring based on the specific charger being installed.
How Far Is the Charger From the Electrical Panel?
Distance matters.
A charger located a few feet from the electrical panel may require a relatively straightforward wiring run.
A charger installed on the other side of the home, in a detached garage, or in another distant location can require a significantly longer run.
The longer the run, the more important proper electrical planning becomes.
Can EV Charger Wiring Run Through the Garage?
Yes.
Garages are a common location for residential EV chargers, and wiring can often be routed through accessible garage areas.
The specific installation method depends on the home’s construction and the location of the electrical panel.
Wiring should be protected appropriately and installed in accordance with applicable electrical requirements.
What About Outdoor Wiring?
Outdoor EV charger installations require additional consideration.
The wiring and electrical components need to be appropriate for the environment and protected as required by the installation.
This is particularly important in Orlando, where electrical equipment may be exposed to heat, humidity, heavy rain, and storms.
An electrician can determine the appropriate wiring method based on where the charger will be installed.
Does the Breaker Need to Match the Wiring?
Yes.
The circuit breaker, wiring, and charger need to be appropriately matched.
The breaker provides protection for the circuit, while the wiring needs to be capable of carrying the electrical load for which the circuit is designed.
Simply installing a larger breaker doesn’t make undersized wiring safe.
The entire circuit needs to be designed as a system.
Can You Use Existing Wiring?
Sometimes, but it should be evaluated first.
An existing circuit may have been designed for a different appliance or electrical load and may not be appropriate for continuous EV charging.
Even if the wiring appears substantial, an electrician needs to determine whether the entire circuit, including the breaker, outlet, connections, and panel, is suitable for the charger.
What If the Wiring Run Is Very Long?
A long wiring run may require additional planning to account for the electrical characteristics of the circuit.
The electrician can determine the appropriate wiring configuration based on the distance, charger requirements, and installation conditions.
If you’re deciding where to place the charger, discussing the location with your electrician beforehand can help avoid an unnecessarily complicated wiring route.
Why Professional EV Charger Wiring Matters
EV charger wiring is not a good place to cut corners.
Improperly sized conductors, loose connections, incorrect breakers, or unsuitable installation methods can create electrical hazards and interfere with charger performance.
A licensed electrician can design and install the circuit around the actual requirements of the equipment and your home.
