Your home’s electrical panel isn’t something you think about often, until it starts acting up.

Flickering lights, burnt smells, blown fuses. These are just a few signs that something’s not right. And as technology advances, older panels often can’t keep up.

So, should you upgrade your electrical panel? Let’s walk through the signs, the pros and cons, the cost, and what to expect during the upgrade process.

Pros and Cons of Upgrading Your Electrical Panel

Upgrading your electrical panel is a big decision. It’s also an investment. But is it the right move for your home?

Let’s look at both sides.

Pros of Upgrading Your Electrical Panel

Enhanced Safety

Older panels can overheat, spark, or even catch fire. Upgrading reduces the risk of electrical hazards, especially if your panel is outdated, overloaded, or recalled (like Zinsco or Federal Pacific).

Increased Electrical Capacity

Today’s homes use more power than ever. From electric vehicles to smart home systems, a modern panel ensures your home can handle the load, without constant tripping.

Enhanced Energy Efficiency

Newer panels are designed to run more efficiently. They distribute power more evenly and reduce strain on your system.

Reduced Insurance Premium

Insurers sometimes offer lower rates to homeowners with updated electrical systems. Some even refuse to cover homes with fuse boxes or outdated panels.

Cons of Upgrading Your Electrical Panel

Cost

The average upgrade runs between $2,000–$4,500, depending on your location, amperage, and panel type. In Sacramento, we see most jobs fall in that range.

Power Disruption

During the upgrade, your home’s power will be shut off for several hours, sometimes a full day. It’s manageable, but you’ll want to plan ahead.

Permit Requirements

Permits are required for panel upgrades. That means scheduling inspections, meeting code, and extra paperwork. (At Old Town Electric, we handle this part for you.)

When To Upgrade Your Electrical Panel: 11 Signs

Sometimes the signs are obvious. Other times, they creep up on you. If you’re seeing any of these, it might be time to call an electrician.

1. It’s Original to Your Home

If your panel is 30+ years old, it’s likely unsafe or outdated, even if it’s “still working.”

2. Need to Flip Breakers Constantly

Tripping breakers are a sign of overload. It means your panel can’t keep up with demand.

3. Your Panel Doesn’t Use Breakers

Still using fuses? It’s time. Fuses are a fire risk and no longer meet today’s safety standards.

4. Your Electrical Panel is Rusted or Broken

Moisture and electricity don’t mix. Rust or corrosion can lead to arcing or complete failure.

5. Not Enough Outlets

Using multiple extension cords or power strips? That’s often a sign your panel can’t support more circuits.

6. Smells Like Something Is Burning

That “burnt plastic” smell near outlets or the panel? Don’t ignore it. Call an electrician immediately.

7. Warm or Hot Electrical Panel

Panels should never feel hot. Warmth means overloading, or worse.

8. You See Sparks When Plugging Things In

This could signal faulty wiring or dangerous surges from the panel.

9. Lights Flicker or Dim When Turning an Appliance On

Your system should handle basic appliances without flickering. If not, your panel’s maxed out.

10. You’re Getting Ready for a Remodel

Adding square footage? You’ll need more circuits, and probably a larger panel.

11. You’re Adding Additional Appliances

Planning to install a tankless water heater, EV charger, or AC unit? You’ll likely need 200-amp service or higher.

Best Time to Upgrade Electrical Panel

The best time to upgrade is before your panel fails.

But timing can also depend on:

Remodeling plans – upgrade during renovations to avoid extra labor
Seasonal needs – spring or fall is ideal in Sacramento to avoid HVAC strain
Home sale prep – buyers and inspectors flag old panels all the time

Don’t wait for an emergency. If your panel’s showing signs now, schedule an assessment soon.

Cost to Upgrade Electrical Panel

Here’s what you can expect:

Upgrade Type	Estimated Cost
100-amp to 200-amp upgrade	$3,000–$5,000+
Complete panel replacement	$3,800–$4,500+
New circuit additions	$300–$600+ per line
Permit & inspection fees	$150–$500+

Prices vary based on the complexity of the job, your home’s wiring, and your city’s permit fees.

We always recommend getting multiple quotes, but make sure you’re comparing licensed electricians with full permit and inspection coverage.

Can You DIY Upgrade Your Electrical Panel?

Let’s be clear: No.

Panel upgrades require a licensed electrician. It’s not just dangerous, it’s illegal to DIY without permits in California.

And honestly? It’s not worth the risk to your home, your family, or your insurance.

Final Takeaway: Don’t Wait for a Fire to Take Action

Old or overloaded panels are more than an inconvenience, they’re a real safety risk.

If your home shows any of the signs above, schedule an inspection. Get a professional’s eyes on it before something goes wrong.
