Rialto Homeowners: Is Your Electrical Panel Ready for an Electric Vehicle?

Posted on November 08, 2025 by Just Electric Services

The shift to electric vehicles (EVs) is well underway, and here in Rialto, California, more and more homeowners are making the switch. But before you drive off in your new EV, it's crucial to ensure your home’s electrical system – specifically your electrical panel – can handle the added load. At Just Electric Services, with over 25 years of experience, we've been helping homeowners throughout the San Gabriel Valley, including Rialto, prepare their homes for the future of driving.

Understanding the Electrical Demand of an EV Charger

EV chargers aren’t like plugging in your phone. They draw *significant* power. The amount of power needed depends on the type of charger (Level 1, Level 2, or DC Fast Charging) and the vehicle itself. Most Level 2 chargers, the standard for home use, require a dedicated 240-volt circuit and can draw between 30 to 80 amps. This can be a substantial increase to your home's electrical load, especially considering the hot summer days we often experience here in Rialto where air conditioning is frequently running.

Before installation, a qualified electrician near me (like our team at Just Electric Services!) needs to assess your current panel’s capacity. Factors considered include:

  • Panel Amperage: Is your panel rated for at least 200 amps? Many older homes in Rialto, particularly in neighborhoods like Renaissance or Pepperwood, may have 100 or 150 amp service which may require an upgrade.
  • Existing Load: What other appliances are currently drawing power simultaneously? (Air conditioner, heater, refrigerator, etc.)
  • Wire Gauge: Are the existing wires adequate to handle the increased demand?
  • Panel Condition: Is your panel showing any signs of wear and tear, corrosion, or overheating?

Preparing Your Rialto Home's Electrical Panel

Here are some common steps your electrical repair Rialto professional might recommend:

  • Panel Upgrade: This is the most common solution for homes with insufficient capacity. We’ll replace your existing panel with a larger one, providing ample power for your EV charger and all your other electrical needs.
  • Subpanel Installation: If a full panel upgrade is not feasible or desired, we can install a subpanel dedicated solely to the EV charger. This requires careful planning to ensure it's properly connected and meets all safety codes.
  • Dedicated Circuit Installation: A dedicated 240V circuit with the appropriate amperage is essential for safe and efficient EV charging. This prevents overloading other circuits.
  • Load Calculation: Our team will perform a detailed load calculation to determine the total electrical demand of your home and ensure your system can handle it.

Rialto’s diverse housing stock – from charming ranch-style homes to newer developments – each presents unique electrical challenges. Our experience allows us to tailor solutions to your specific property.

Safety First: Why Hire a Qualified Electrician?

Working with electricity is dangerous. Incorrect installation of an EV charger can lead to fire hazards, electrical shocks, and damage to your vehicle. Don't attempt this as a DIY project. A licensed and insured electrician, like those at Just Electric Services, will ensure the installation is done safely and according to all local codes.

We understand that unexpected electrical issues can arise. That’s why we also offer Emergency electrician Rialto services, available 24/7 to address urgent electrical problems.
