Installing a home charger can feel overwhelming, especially if it’s your first time working with an EV charger installer in Orlando. With terms like breaker sizing, wire gauge, and the National Electrical Code popping up everywhere, it’s easy to get confused fast.
This guide breaks everything down into simple language so you can understand the wiring needed, the 80% rule, and what makes a safe installation.
Let’s walk through what Orlando homeowners should know before installing a charging station at home.
What Wire Size Do You Actually Need fo+r Level 2 EV Charging?
Wire size depends on the charger amperage, breaker rating, and continuous load rules from the National Electrical Code (NEC). A trusted EV charger installer will also confirm if your setup needs thicker wiring for higher amperage to prevent heat buildup or voltage drop.
General wire gauge guide:
|
Charger Amperage |
Breaker Size |
Typical Wire Gauge |
|---|---|---|
|
20A Charger |
25A Breaker |
12 AWG |
|
32A Charger |
40A Breaker |
8 AWG |
|
40A Charger |
50A Breaker |
6 AWG |
|
48A Charger |
60A Breaker |
6 AWG |
Always check local jurisdiction codes and the charging unit’s manufacturer guidelines.
What Breaker Size Do You Need for Level 2 EV Charging?
Breakers must be sized for continuous load, which EV charging qualifies as because it can run for hours. A professional EV charger installer ensures the breaker matches your charger’s amperage and wiring needs.
The NEC requires that EV chargers only draw 80% of the breaker’s capacity, meaning a “50A breaker” can safely supply only 40A to the charger. This is called the 80% rule, and it’s critical to avoid overheating or tripping the breaker.

64A (rare) |
80A |
64A is 80% of an 80A breaker |
What Is the 80% Rule and Why Does It Matter?
The 80% rule ensures your circuit remains stable even during long charging sessions. Following this rule also helps a licensed electrician ensure your home’s electrical system has sufficient capacity for future proof upgrades like solar, two EVs, or other electrification technologies.
Why Licensed Electricians Recommend Following the 80% Rule
Licensed electricians in Orlando strictly follow the 80% rule because EV charging is considered a continuous load. This prevents overheating, extends the life of the breaker, and ensures safety for long overnight charging.
A trusted EV charger installer also considers the panel, wiring, proper breaker rated capacity, and voltage drop. Doing so keeps your system ready to install additional electrification technologies in the future.
Do You Need a Panel Upgrade for Your EV Charging Station?
Sometimes your main panel simply doesn’t have available capacity to handle an EV charging station. A panel upgrade may be needed if:
- Your electrical panel is outdated
- Your home has limited breaker spaces
- You plan to power two EVs
- You want to future proof your system for smart features or higher amperage
A licensed electrician or EV charger installer checks the electrical system, breaker availability, and wiring needed. In some cases, trenching required for detached garages may also be part of the installation process. While it adds cost, a panel upgrade ensures safety and prevents overloads.
Wiring Requirements Homeowners Often Overlook
Orlando installations must follow local code, NEC rules, and manufacturer specs.
Factors that affect wiring include:
- Wiring runs distance
- Potential voltage drop
- Whether trenching is required
- If the charger needs its own circuit
- Whether GFCI protection applies
- Required permits, inspections, and applicable fees
These affect cost, timeline, and safety.
What Permits and Local Codes Affect EV Charger Installation?
Orlando’s local jurisdiction requires necessary permits before installing electric vehicle supply equipment. These rules ensure a safe installation that follows national electrical code standards.
Applicable fees related to required permits vary depending on the setup, wiring, panel work, and other repairs. A certified EV charger installer ensures the installation is inspected and verified to provide sufficient capacity and follow the correct circuit requirements.
Whether you’re using a Qmerit certified installer or a local professional, adhering to local code protects your home and validates your installation.
Key Wiring Components Every Homeowner Should Understand
Understanding the key wiring components in your EV setup helps you ensure safety, avoid overloads, and get reliable charging performance. Here are the essentials every homeowner should know before installing a charger.
1. Electrical Panel Capacity
Your main panel must have sufficient capacity to handle the continuous load of EV charging. If the panel is full or outdated, a panel upgrade ensures safe installation.
2. Wire Gauge
Wire gauge protects your electric vehicle and the system from overheating. Smaller homes or older properties often need upgraded wiring to accommodate additional electrification technologies.
3. Circuit Breaker Selection
The circuit breaker must match the charger amperage and follow the breaker rated 80% continuous load rule. This prevents overloads and complies with north america’s safety standards.
4. Wiring Runs & Location Choices
Longer wiring runs increase voltage drop. Installers check the best placement for your home EV charging station to save money and maintain optimal power.
5. Smart Features & Future-Proofing
Modern EV chargers come with smart features, allowing scheduling, power monitoring, and integration with other repairs or technologies. A future proof setup matters if you plan to add two EVs or higher-amperage chargers later.
Can Your Home Handle More Power for EV Charging?
Homes built before modern electrification often struggle to accommodate additional electrification technologies. The main panel may not provide sufficient capacity for faster charging or higher amperage chargers.
A professional EV charger installer examines whether your electrical system can safely support the charger, future proof upgrades, and smart charging capabilities. When needed, EV charger installation near me services may also recommend a panel upgrade or dedicated wiring runs.
This step prevents voltage drop issues and ensures the circuit breaker can handle continuous load cycles.
Choosing the Right Installation Professional in Orlando
Not all installers understand the complexity of EV systems and electrical panels. Look for:
- A certified installer
- Licensed electricians familiar with local code
- Experience with electric vehicle supply equipment
- Ability to install Level 2 EV chargers and smart charging unit setups
Companies that work with the Qmerit network or provide online assessment tools help homeowners save money and get safe installation options quicker. Their expertise ensures the wiring needed is correct, the breaker’s capacity is aligned, and all trenching required or panel upgrades are handled professionally.
