Thinking About an EV Charger in National City? Start With Your Panel

This is one of the most common reasons National City homeowners call us for panel replacements.
When it comes to EV chargers, our experience shows that a hardwired unit is more reliable and safer than a plug-in model. Hardwiring reduces outlet wear and ensures the charger operates at its full capacity without interruptions.

Warning Signs That Your National City Home Needs a Panel Upgrade
Below are a few reasons you might need an electrical panel upgrade or replacement:
Breakers keep tripping
Melted bus bar from a faulty circuit
A burning smell is coming from the electrical panel
The electrical panel is deteriorating
More amperage is needed for added loads such as an electric vehicle, oven, fireplace, heat pump, or mini-split
These are a few of the many reasons National City homeowners and businesses consider upgrading their electrical panel.
The Real Value of Upgrading Your Panel in National City
In short, yes, there is a real advantage.
Many people buy a home in National City and spend their money on strictly cosmetic upgrades. One thing to keep in mind, especially with electrical upgrades, is the importance of the backbone of your electrical system.
The backbone consists of all the wires and materials you cannot see, with the electrical panel being the main component.
It is not the most glamorous upgrade. It is not going to impress your friends or make your bathroom look modern and up to date. However, a properly operating electrical panel will ensure that all the new light fixtures, smart switches, ceiling fans, and other components you install continue to operate without interruption for many years to come.

The cost of upgrading your electrical panel in National City can vary depending on your specific installation requirements.
Below are the two most typical cost ranges in the National City and greater San Diego area:

What to Expect During a Panel Upgrade in National City, CA
Now that we have covered the basics, here is what to expect from start to finish, including the differences between overhead and underground electrical panel upgrades in National City.
Full Process Overview
Request Service Change From SDG&E (San Diego Gas and Electric)
Waiting Period
Apply For a City Permit (City of National City)
Schedule Pre-Meet With Trench Inspector (Underground Service Only)
Dig Trench and Install Conduit (Underground Service Only)
Trench Inspection and Backfill (Underground Service Only)
Schedule Disconnect and Reconnect
Utility Company Power Disconnection
Install Grounding and Bonding System
Electrical Panel Removal and Installation
Repair Stucco or Siding
Pass Final Inspection
Step 1: Contact SDG&E to Request a Service Change
To get your project started in National City, you must first request a change to your existing service from SDG&E (San Diego Gas and Electric), the local utility company serving National City and the surrounding San Diego area.
Steps to complete this:
Go to SDG&E's work order request form at sdge.com/apply-service
Fill out all the necessary information for your installation
Review all the forms and click submit
This paperwork is typically included in the cost of your electrical panel upgrade. When you hire Landers Electric, there is no need to fill out any of the paperwork yourself.
Step 2: Wait for SDG&E to Assign a Planner
Once you have submitted a work order, the waiting period begins. After this period, your project is assigned to an SDG&E planner who will come to your National City home and assess the area.
The planner will then send a detailed work order with the specific requirements for your panel upgrade, including:
Panel location
Conduit size
Clearances
Meter height
Trenching route and depth (underground service only)
Step 3: Apply for a Permit With the City of National City
After receiving the SDG&E work order, you must contact the City of National City and apply for a permit. National City is its own city, and all electrical permits are issued through the City of National City Building Department.
A CITY PERMIT IS ALWAYS REQUIRED when upgrading an electrical panel in National City.
There are many so-called electricians who will quote you a much lower price and tell you that a permit is not necessary. If you come across one of these unprofessional contractors, do not hire them.
Obtaining a permit for an electrical panel upgrade in National City is a straightforward process. Not sure how to handle permits? 📞 Call Landers Electric today at (760) 690-7517 or Text Us Anytime. We pull all required City of National City permits and handle all the paperwork for you.
Step 4: Meet With the SDG&E Trench Inspector (Underground Service Only)
If your National City home has an underground electrical service, you must schedule a pre-meet with an SDG&E trench inspector before any digging begins. This meeting ensures that the new underground conduit will be installed according to SDG&E standards.
It is important to call Dig Alert (811) before scheduling this meeting. The work area must be marked with white paint before Dig Alert arrives. You will not be able to schedule the meeting without a Dig Alert reference number.
Step 5: Excavate the Trench and Run the Conduit (Underground Service Only)
Once the trench inspector has provided the necessary direction, construction can begin. The trench is excavated, and approximately 90 percent of the conduit is installed. The final 10 percent, which is the portion that enters SDG&E's handhole or transformer, is installed by a utility contractor after the second trench inspection.
Step 6: Trench Inspection and Backfill (Underground Service Only)
After 90 percent of the conduit is in place, the trench inspector returns for a second approval. Once cleared, an SDG&E crew completes the conduit installation. The electrical contractor then backfills the trench and repairs any driveway, sidewalk, or street that was disturbed during digging. A final trench inspection is required before the project can proceed.
Step 7: Book the Disconnect and Reconnect Date
Steps 7 through 12 apply to both overhead and underground services.
The disconnect and reconnect date is the day the old electrical panel will be removed and the new one installed. This is scheduled by contacting the SDG&E service coordinator. The City of National City must also be notified so they can schedule their inspection for the same day.
Step 8: SDG&E Arrives to Disconnect Power
On the day of your electrical panel upgrade, an SDG&E crew will arrive early in the morning to disconnect power.
Important: Approximately three days before the scheduled disconnection date, call Dig Alert (811) to have all existing utilities marked, including gas, water, AT&T, Cox Cable, and others.
Step 9: Set Up the Grounding and Bonding System
The National Electrical Code requires proper grounding and bonding on all new electrical panels.
This includes:
Two ground rods driven eight feet into the ground
Cold water bond
Electrical panel connection
Proper grounding is required by the NEC. If you would prefer to leave this to a licensed professional, 📞 Call Landers Electric today at (760) 690-7517 or Text Us Anytime.
Step 10: Pull Out the Old Panel and Put In the New One
THIS STEP CAN ONLY BE COMPLETED ONCE SDG&E HAS DISCONNECTED THE POWER.
Once power is disconnected, the old panel is removed, and the new panel is installed. For overhead service in National City, a new riser and weatherhead will be installed at least 24 inches above the roof for the utility connection.
After the installation is complete, the City of National City inspector will visit the site to verify that everything is in compliance with the National Electrical Code. Once the inspection is approved, SDG&E will restore power to the property.
Step 11: Fix the Stucco or Siding
Removing an electrical panel requires cutting into the stucco or siding of your National City home. All repairs must be completed before a final inspection can be scheduled. These repairs can be handled by Landers Electric or coordinated with another contractor.
Step 12: Pass the Final Inspection
The final inspection by the City of National City is the last milestone in the panel upgrade process. The stucco or siding must be repaired, the waterproofing restored, and the affected area painted before the inspection can be passed.
Once the final inspection is approved, the electrical panel upgrade is complete!
When you hire Landers Electric, we stay on the job until the City of National City inspection is passed and your power is safely restored. 📞 Call Landers Electric today at (760) 690-7517 or Text Us Anytime.
