PANEL UPGRADES

Older Oakland Homes, Modern Electrical Loads

An undersized or aging panel is behind more electrical problems than people realize: tripped breakers, flickering lights, and a system that can't keep up with modern appliances, EV chargers, or a home addition.

Our professionally installed electricians assess your existing panel, explain what's actually needed, and handle the permit and inspection process from start to finish.

 Trustindex verifies that the original source of the review is Google. We had VoltGuard Electric & Security come out for an electrical issue we’d been putting off, and I’m really glad we chose them. They showed up on time, were friendly, and got right to work. They took the time to explain everything in a way that made sense and never made us feel pressured into anything extra.

The work turned out great, and you can tell they know what they’re doing. Everything was clean when they finished, and it’s been working perfectly ever since. It’s refreshing to find a company that’s reliable, communicates well, and actually follows through on what they promise.

I’d definitely recommend VoltGuard Electric & Security to anyone who needs electrical work done. Great experience from start to finish, and I’ll be using them again in the future.

COMMON QUESTIONS

Frequently Asked Questions

How do I know if I need a panel upgrade?

Common signs include breakers that trip frequently, flickering lights, a panel rated below 100A, warm or discolored outlets, or plans to add an EV charger, hot tub, or home addition. We can assess your panel and tell you honestly whether an upgrade is needed.

How long does a panel upgrade take?

Most residential panel upgrades are completed in a single day, including the swap and reconnection. Power is typically off for only a few hours during the actual changeover.

Do I need a permit for a panel upgrade?

Yes, panel upgrades require a City of Oakland permit and inspection. We handle the entire permit process as part of the project so you don't have to deal with the paperwork.

What size panel do I need?

Most modern homes are well served by a 200A panel, though the right size depends on your home's square footage and planned electrical loads like EV charging or HVAC. We'll calculate this during the site assessment.

Is my panel dangerous if it's an older brand?

Certain older panel brands, including some Federal Pacific and Zinsco models, have documented safety issues and are worth replacing proactively even if they appear to be working. We can identify your panel brand and advise you honestly.

Can you upgrade my panel without a full remodel?

Yes. A panel upgrade is a standalone project and does not require any other renovation work.

Do you offer financing or payment plans for panel upgrades?

Ask us about payment options when you request your estimate. We'll walk you through what's available for your project.
