Charging Infrastructure That Supports Your Vehicle

Empire Electric Co installs Level 2 EV chargers for homes and businesses in Rancho Cucamonga and throughout the Inland Empire.

When you drive an electric vehicle in Rancho Cucamonga, Ontario, Eastvale or a surrounding area, charging overnight at home or during the workday at the office becomes part of your routine. A Level 2 charger delivers faster charging than a standard outlet, typically adding twenty to thirty miles of range per hour. Empire Electric Co installs the charging unit, runs the circuit from your panel, and ensures the installation meets code requirements in Rancho Cucamonga.


This service includes a panel evaluation to confirm your electrical system has the capacity to support a 240-volt charging circuit without overloading the main breaker. We install a dedicated breaker, run conduit and wire to the charger location, and mount the unit on the wall of your garage or exterior parking area. If your panel lacks available space or capacity, we recommend a panel upgrade or load management system before proceeding with the charger installation.

Panel Capacity and Circuit Requirements Explained

We begin by opening your electrical panel and calculating the total load to determine if a 40- or 50-amp circuit can be added without exceeding service capacity. In Rancho Cucamonga or a surrounding area, most Level 2 chargers require a 240-volt circuit with a dedicated breaker, similar to the wiring used for electric dryers or ovens. We run conduit from the panel to the charger location, pull wire rated for the amperage, and install a NEMA 14-50 receptacle or hardwire the unit depending on the charger model.


Once the charger is mounted and wired, you will plug in your vehicle and see the charging indicator light up, with a full charge typically taking four to eight hours depending on battery size. The circuit operates independently from the rest of your home, so charging your car does not interfere with lights, appliances, or HVAC systems.


We also obtain the required electrical permit and coordinate the final inspection with the city to ensure compliance with current codes. For commercial installations, we can install multiple chargers on a single circuit using load-sharing technology or run separate circuits for simultaneous charging. This service does not include trenching for underground conduit runs longer than fifty feet, which may require additional coordination.

Questions You Might Have Before Installing

EV charger installations involve panel capacity, circuit sizing, and permitting requirements that vary based on your electrical system and the charger model you choose, so it helps to understand what the installation process looks like and what your panel needs to support.

What is the difference between Level 1 and Level 2 charging?
Level 1 uses a standard 120-volt outlet and adds three to five miles of range per hour, while Level 2 uses a 240-volt circuit and adds twenty to thirty miles per hour. Most drivers install Level 2 chargers for faster overnight charging.
How do you know if my panel can handle a charger?
We calculate the total load on your panel and compare it to the service rating, typically 100, 150, or 200 amps. If the panel is near capacity, we recommend a panel upgrade or a load management device that prioritizes charging when other circuits are not in use.
How long does the installation take?
Most residential installations take four to six hours, including running the circuit and mounting the charger. Commercial installations with multiple chargers or longer conduit runs may take one to two days depending on site conditions.
What permits are required for EV charger installation?
An electrical permit is required in most jurisdictions, and the installation must pass a final inspection before the charger is used. We handle the permit application and schedule the inspection on your behalf.
Can I install a charger if I have solar panels?
Yes, EV chargers work with solar systems and can draw power from the grid or solar production depending on the time of day. We coordinate with your solar installer if any modifications to the interconnection are needed.
