How It Works
We keep the process straightforward from first call to finished job.
We evaluate your current panel, load requirements, and any planned additions like EV chargers or new circuits to determine exactly what the upgrade needs to include.
We outline the full scope of work, pull the necessary permits, and schedule the job around your availability so there are no surprises.
Our licensed electricians complete the panel swap, label all circuits clearly, and verify that every breaker is properly sized and seated before restoring power.
We coordinate with the local inspector, address any items on the spot, and make sure you receive a clean sign-off before we close out the job.
Frequently asked
Common questions get answered quickly so the page feels more trustworthy before someone reaches out.
Q1
Common signs include frequently tripping breakers, a fuse box instead of a breaker panel, flickering lights, or plans to add a high-draw appliance like an EV charger or central air unit. A quick inspection usually tells the full story.
Q2
Many older Bay Area homes have 100-amp panels, which often isn't enough for modern loads. A 200-amp upgrade is standard for most single-family homes today. Larger homes or those with multiple high-draw circuits may need more.
Q3
Yes. Panel upgrades require a permit from the city of Fremont and must be inspected. High Voltage Electric handles the permit application and inspection coordination as part of the job.
Q4
Yes, there will be a period without power while the old panel is removed and the new one is connected. We schedule and complete the work efficiently to keep that window as short as possible.
Q5
Absolutely. A panel upgrade is often the first step before installing a Level 2 EV charger. We can plan both services together so the panel is sized correctly from the start.
Q6
Most panel upgrades are completed in a single day. More complex jobs involving a service entrance upgrade or sub-panel work may take longer, but we'll give you a clear timeline before we start.
Q7
Yes. We serve Hayward, Oakland, San Leandro, Union City, Castro Valley, San Lorenzo, and Emeryville in addition to Fremont.
Q8
We install panels from established, code-accepted manufacturers. During your assessment, we'll discuss which option fits your home's needs and talk through any preferences you have.
