Know the Warning Signs
8 Signs Your Denver Home Needs an Electrical Panel Upgrade
Denver homes built before 1990 are especially vulnerable. If you recognize any of these signs, contact The Electricians for a free inspection before a minor issue becomes a major hazard.
01
A breaker that trips once is doing its job. A breaker that trips repeatedly on the same circuit signals an overloaded system or a failing breaker that needs immediate evaluation.
02
If lights dim when a large appliance starts, your panel is struggling to manage load. A classic sign that 100-amp service can no longer keep pace with modern electrical demand.
03
A burning smell, discoloration, or a panel that feels warm to the touch indicates overheating. This is a fire risk and requires an immediate call to a licensed electrician.
04
Panels are designed to last 25 to 40 years. If your Denver home was built before 2000, your panel is approaching or past its service life and should be professionally inspected.
05
Federal Pacific Electric (Stab-Lok), Zinsco, Bulldog Pushmatic, GE Split-Bus, or Gould panels require immediate replacement. These brands have documented safety failures and fire risk histories.
06
Planning to add an EV charger, heat pump, hot tub, or home addition? If your panel has no open breaker slots, you need a panel upgrade or subpanel before any new circuit can be safely added.
07
Fuse boxes are the original panels in older Denver homes. They are outdated, incompatible with modern appliances, and create significant insurance and safety issues. Replacement is strongly recommended.
08
Many Colorado insurers decline to write new policies on homes with Federal Pacific or Zinsco panels. If your insurer has flagged your panel, we provide same-day in-person estimates for replacement.

Safety Alert
Is Your Denver Home’s Panel on the Recall List?
Denver homes built between the 1950s and early 1990s have a high probability of containing a recalled electrical panel. These panels have documented histories of breaker failure that can lead to electrical fires. Many Colorado homeowners do not know they have one.
Federal Pacific Electric (FPE) Stab-Lok
Federal Pacific Electric was one of the most widely used panel manufacturers in the United States from the 1950s through the early 1980s. Their Stab-Lok breakers were installed in an enormous number of Denver homes built during the postwar expansion across neighborhoods like Stapleton, Congress Park, Harvey Park, and Bear Valley.
A 2002 New Jersey court found that FPE had falsified UL certification testing data for its Stab-Lok breakers. Independent studies have shown these breakers fail to trip during electrical surges at unacceptable rates — which means the primary safety mechanism designed to prevent electrical fires may not function when your home needs it most.
Colorado insurer alert: Many homeowners insurance carriers will not write new policies or will cancel existing policies on homes with Federal Pacific panels. Replacement typically costs $3,000–$6,000 in Denver and takes one day.
Zinsco / Sylvania and Other Recalled Brands
Zinsco panels (also sold under the Sylvania name) were common in Colorado homes through the mid-1970s. Like FPE, Zinsco breakers have a documented history of failing to trip under fault conditions and of physically fusing to the bus bar, making them impossible to shut off manually.
Bulldog Pushmatic — push-button breakers no longer serviceable
GE Split-Bus Panels — split-bus design with known overloading vulnerability
Gould / ITE — obsolete panels with parts no longer available

Electrical Panel Upgrades in Denver: What Every Homeowner Should Know
Denver and the surrounding metro sits on an unusually large stock of aging residential housing. Neighborhoods like Wheat Ridge, Arvada, Harvey Park, Overland Park, and the older sections of Lakewood and Aurora contain thousands of homes still running on 100-amp or smaller panels installed decades before modern appliances, smart home systems, and electric vehicles existed as everyday considerations. For these homeowners, an electrical panel upgrade in Denver is not a luxury — it is the foundational upgrade that makes everything else possible.
The Electricians performs electrical panel upgrades throughout the Denver metro including Denver, Centennial, Aurora, Littleton, Highlands Ranch, Lakewood, Parker, Castle Rock, and all surrounding communities. Every job includes free FLIR thermal imaging, permit coordination, city inspection, and a 100% satisfaction guarantee.
What Size Electrical Panel Does Your Denver Home Need?
Choosing the right panel size depends on your home’s square footage, current appliances, and what you plan to add in the coming years. Here is the practical guide The Electricians uses for Denver homes:
Panel Upgrades and EV Chargers in Denver
Colorado leads the nation in electric vehicle adoption, and a Level 2 home EV charger requires a dedicated 240-volt circuit drawing 40 to 50 amps. For most Denver homes still on 100-amp service, adding an EV charger without upgrading the panel first is not possible. The Electricians frequently completes panel upgrade and EV charger installation as a single project, which reduces total cost, requires only one permit, and qualifies for Xcel Energy rebates.
For Denver homeowners planning both together, the combined project typically ranges from $3,500 to $6,500 before applicable rebates. Call (720) 303-0150 for a free in-person estimate that covers both projects in a single visit.

What Customers Say
Denver Homeowners on Our Panel Work
★★★★★ 4.9 • 300+ Google Reviews
“Our home was built in 1978 and still had the original Federal Pacific panel. The Electricians came out the same day I called. Mani explained everything clearly before starting. The upgrade was completed in one day and passed inspection the first time.”
“I needed a 200 amp panel upgrade before installing a Tesla Wall Connector. The Electricians handled both projects in a single day. They coordinated directly with Xcel and handled the rebate paperwork. Saved me hundreds and the installation was flawless.”
“The FLIR thermal imaging they did on our panel found a failing breaker I never knew about. They showed me the heat signature on the camera and replaced it on the spot. That kind of diagnostic technology is exactly what separates a real professional from the rest.”
