Switching to an electric vehicle (EV) is an exciting milestone for any homeowner. However, the transition from a gas station to a home charging port involves more than just plugging in a cord. It requires a fundamental shift in how your home consumes power.
At Root Electric, we believe your home should be your "lighting paradise," not a source of electrical stress. With over 30 years of combined experience, our team specializes in turning complex electrical concerns into seamless, safe solutions. When it comes to Level 2 EV charging, cutting corners isn't just a budget risk—it’s a safety risk for your family and your property.
Deep Dive: The Science of Load Calculations
One of the most critical steps we take at Root Electric is performing a professional load calculation. But what does that actually mean for you? Your home’s electrical panel has a finite capacity, typically measured in Amps (e.g., 100-amp, 150-amp, or 200-amp service). A Level 2 EV charger is a "continuous load" device, meaning it draws a high amount of electricity for hours at a time. If you add a 48-amp charger to a 100-amp panel that is already supporting an electric range, an HVAC system, and a clothes dryer, you are flirting with a total system failure.
Our Load Calculation Process:
- Inventory of Appliances: We tally the "fixed loads" of your home to see how much "room" is left on your main bus bar.
- Square Footage Assessment: Standard electrical codes require a certain wattage per square foot for general lighting and outlets.
- Future-Proofing for Expansion: We don't just look at today. If you plan on finishing your basement, adding a hot tub, or buying a second EV in three years, we factor that in now.
- Transparency: If your panel is at capacity, we won't just "squeeze it in." We provide clear options for service upgrades or smart load-shedding devices, ensuring there is no second-guessing your home's safety.
Common DIY and "Cheap" Contractor Mistakes
We often get calls to fix "second-guessed" electrical work. Here are the most common—and dangerous—mistakes we see when EV chargers aren't installed by specialists:
- Using Residential-Grade Outlets for High-Heat Loads:
If you aren't hardwiring your charger, you need a NEMA 14-50 plug. Many "big box" stores sell residential-grade outlets meant for dryers. However, an EV charger draws max power for 8+ hours, whereas a dryer cycles on and off. The Danger: A cheap $15 outlet can melt, smoke, or catch fire under the sustained heat of an EV charge. At Root Electric, we use industrial-grade, high-torque receptacles designed to handle the heat.
- Undersized Wiring (Voltage Drop and Overheating)
Wire size is not a suggestion; it’s a matter of physics. If a contractor uses a wire gauge that is too thin for the distance between your panel and the garage, the wire will resist the flow of electricity.
The Result: This resistance creates heat. Over time, the insulation on the wire can become brittle and fail. We use spec wire sizes that exceed minimum code requirements to ensure efficiency and longevity.
- Incorrect Breaker Sizing: A 40-amp charger requires a 50-amp breaker (the "80% Rule"). We see many installs where the breaker is "sized to the load" rather than being oversized for a continuous load. This leads to "nuisance tripping," where your car stops charging in the middle of the night, leaving you stranded in the morning.
Beyond the Wire: 30 Years of Combined Knowledge
The Root Electric difference is that our knowledge doesn't stop at the breaker box. We understand the software, the hardware, and the human element.
Lighting & Controls Integration
We don't just give you a plug; we can turn your garage into a "lighting paradise." Whether you want motion-controlled LED shop lights to guide you into your parking spot or smart home integration that schedules your charging for when electricity rates are lowest, we have the expertise to make it happen.
Troubleshooting and Communication
The best part about our company is our commitment to communication. If we arrive and realize the issue is a simple software setting on your vehicle or a tripped GFCI that you can reset yourself, we walk you through it. We believe in honesty over a quick paycheck. If we aren't needed, we tell you. That is how we have built 30 years of trust.
Fact & Answer Section (FAQ)
Q: What is the difference between a Level 1 and a Level 2 charger?
A: Level 1 uses a standard 120V wall outlet and adds about 3-5 miles of range per hour. Level 2 (Stage 2) uses a 240V circuit and can add 25-60 miles of range per hour. Because Level 2 uses significantly more power, it requires professional load calculations and dedicated circuitry.
Q: Why is "Hardwiring" often better than using a plug?
A: Hardwiring removes a "point of failure" (the plug/outlet connection). It allows for higher charging speeds (up to 48 or 80 amps) and is generally more weather-resistant if the charger is located outdoors.
Q: Does installing an EV charger void my home insurance?
A: Not if it is installed by a licensed professional and permitted according to local codes. However, a DIY install that causes a fire could lead to a claim denial. Root Electric provides the documentation and "right-the-first-time" quality that keeps your insurance company happy.
Q: Can you install a charger if my panel is full?
A: Yes! We can often use "tandem" breakers to make space, or we can install a sub-panel. In cases where the main service is too small, we offer transparent pricing on service upgrades to 200-amp or 400-amp systems.
