Your electrical panel is the heart of your home’s power system. It directs electricity from the utility company into the various circuits that power everything from your lights and refrigerator to your HVAC system and electric vehicle charger.
Over time, electrical panels wear out or become outdated. As modern homes require more power for new appliances and technology, older panels often can’t keep up. Knowing when to replace your electrical panel can help you avoid power interruptions, improve safety, and ensure your system meets today’s electrical demands.
At Point Loma Electric, Plumbing, Heating & Air, we’ve helped San Diego homeowners upgrade outdated panels for decades. Here’s how to know if it’s time to replace yours.
How to Tell if an Electrical Panel Needs Replacing
Here are 8 telltale signs you need to upgrade your electrical panel:
1. Your Home Still Has an Old Fuse Box
If your home was built before the 1970s, it may still have a fuse box instead of a circuit breaker panel. Fuse boxes were once standard, but they’re not designed for modern energy use.
Fuses blow when circuits overload, requiring manual replacement each time. Circuit breakers, on the other hand, can simply be reset and are far safer and more efficient. If you’re still relying on fuses, it’s a clear sign that it’s time to upgrade to a modern breaker panel.
2. Your Electrical Panel Is More Than 25 Years Old
Most panels are designed to last about 25 to 40 years. After that, parts begin to wear down, corrosion can set in, and the internal components may no longer function safely.
Older panels weren’t built to handle the electrical load of today’s homes. Between smart appliances, computers, air conditioning, and electric vehicles, energy demands are higher than ever. If your panel is nearing the end of its lifespan, consider scheduling an inspection to determine whether replacement is needed.
3. You Frequently Trip Circuit Breakers
Occasional breaker trips aren’t unusual—they’re a built-in safety measure. But if you find yourself constantly resetting breakers, that’s a sign your system is overloaded.
Frequent trips may mean your panel can’t distribute power efficiently or has internal wear that prevents it from managing your home’s electrical flow. Replacing the panel can restore performance and prevent more serious problems like overheating or electrical fires.
4. You Notice Burning Smells or Scorch Marks
Any sign of heat, burning, or smoke near your panel is a serious red flag. Scorch marks, buzzing sounds, or a faint burning smell can indicate loose connections, melted wires, or corrosion inside the panel.
These issues pose a major fire risk and should be addressed immediately. Shut off power to the affected circuits and call a licensed electrician right away. In most cases, this is a clear sign that the panel needs to be replaced.
5. Lights Flicker or Appliances Struggle to Run
When your electrical system can’t deliver consistent voltage, you may notice flickering lights, dimming when large appliances turn on, or random power fluctuations.
This can happen when your panel’s breakers or wiring are failing. It can also indicate that your home’s electrical system is underpowered. Installing a new panel helps regulate current and ensures your devices receive stable power, protecting sensitive electronics and appliances from damage.
6. You’re Adding New Electrical Loads
Adding new appliances or remodeling your home often increases electrical demand. If you’re installing a new HVAC system, hot tub, EV charger, or home addition, your old panel may not have the capacity to handle the extra load.
Upgrading to a panel with higher amperage ensures your system can safely power everything without risking overload. Most older homes have 100-amp panels, while modern systems typically use 200 amps or more to meet increased energy needs.
7. Your Panel Is a Recalled or Unsafe
Some electrical panel brands from past decades—such as Federal Pacific Electric (FPE) or Zinsco—are known to have design flaws that make them unsafe. These panels may fail to trip when circuits overload, greatly increasing the risk of fire.
If your home still has one of these panels, it’s important to have it replaced as soon as possible. A licensed electrician can confirm your panel’s brand and model and recommend the best replacement options.
8. You’re Upgrading Other Parts of Your Electrical System
Replacing your electrical panel often goes hand-in-hand with other electrical upgrades. If you’re rewiring your home, adding outlets, or installing solar panels, it’s a good opportunity to update your panel at the same time.
A modern panel not only improves efficiency but also adds resale value to your home, ensuring that your electrical system meets current safety standards.
