Electrical panels are essential components of any electrical system, controlling and distributing power throughout a building. Over the decades, many electrical panel brands have emerged, each with distinct qualities, technologies, and history. Some of these brands are still in use today, while others have been phased out. This article takes a deep dive into old electrical panel brands, offering insights into their importance, features, comparisons, and answering key questions.

1. Introduction to Old Electrical Panel Brands
Electrical panels, also known as breaker panels or load centers, have evolved significantly over time. Many older panels were built before modern safety standards were introduced, making them obsolete or dangerous by today’s regulations. Old electrical panel brands, however, are still found in many older homes and commercial buildings.
Understanding the brand of your electrical panel can help you assess whether it’s safe, reliable, or needs an upgrade. Many electricians and homeowners deal with older brands like Federal Pacific Electric (FPE), Zinsco, and Pushmatic, which were once popular but now pose safety risks.
2. Importance of Choosing the Right Electrical Panel
Choosing the right electrical panel is critical to ensure safety and efficiency in your home. Panels from outdated brands may no longer meet current safety codes, increasing the risk of electrical fires or malfunctions. Modern panels, on the other hand, are built to handle the higher electrical demands of today’s homes, with features like arc-fault protection, ground-fault protection, and surge protection.
When considering upgrading or inspecting an old panel, it’s crucial to consult a licensed electrician. Some of these old brands are notorious for having defective circuit breakers, which can fail to trip during an overload, leading to electrical fires.
3. Popular Old Electrical Panel Brands
Let’s explore some of the most popular old electrical panel brands that are often found in older homes:
Federal Pacific Electric (FPE)
One of the most controversial old electrical panel brands, Federal Pacific Electric panels were commonly installed between the 1950s and 1980s. FPE panels, particularly their Stab-Lok breakers, are notorious for failing to trip during a short circuit, leading to serious fire hazards. Although they were widely used due to their affordability, they are now highly discouraged and recommended for replacement.
Common Issues:
- Breakers fail to trip
- Fire hazards
- Panels often overheat
Zinsco
Zinsco panels were widely installed from the 1950s to the 1970s. Similar to FPE, Zinsco panels have significant safety concerns. The breakers in these panels often fuse to the bus bar, leading to overheating and failure to disconnect the current during an overload.
Common Issues:
- Breakers may not trip in the event of overload
- Prone to corrosion and arcing
- High fire risk
Wadsworth
Wadsworth electrical panels were quite popular in the 1950s and 1960s, but the brand faded over time. While not as notorious as FPE or Zinsco, these panels are no longer manufactured, making replacements difficult to find. If a Wadsworth panel needs repair, it may be best to upgrade to a newer model.
Common Issues:
- Outdated technology
- Limited availability of replacement parts
Pushmatic
Pushmatic panels, produced by Bulldog Electric, were unique in that they did not use standard breakers but rather push-button switches. While reliable for their time, they are now considered obsolete. These panels have no magnetic trip mechanism, making them less responsive to electrical surges.
Common Issues:
- No longer in production
- Difficult to find replacement breakers
- No magnetic trip mechanism, resulting in delayed response to faults
General Electric (GE)
General Electric (GE) is a well-known brand that has been producing electrical panels for decades. While many GE panels from the 1960s and 1970s are still in use today, the older models do not meet current safety standards. Newer GE panels, however, are much safer and up-to-date with modern electrical codes.
Common Issues:
- Older models may not meet modern safety standards
- Wear and tear over time
4. Comparison of Old Electrical Panels
| Brand | Known Issues | Production Period | Current Status |
|---|---|---|---|
| FPE (Stab-Lok) | Breakers fail to trip, fire risk | 1950s-1980s | Discontinued, unsafe |
| Zinsco | Breakers fuse, fire hazard | 1950s-1970s | Discontinued, unsafe |
| Wadsworth | Difficult to find parts | 1950s-1960s | Outdated, limited parts |
| Pushmatic | No magnetic trip mechanism | 1950s-1980s | Obsolete, no new parts |
| GE | Outdated technology | 1960s-1970s (older models) | New models available |
5. Risks Associated with Outdated Electrical Panels
Old electrical panels present serious risks. These panels often fail to provide adequate protection from overcurrents, short circuits, or electrical surges. Some risks include:
- Electrical Fires: If a breaker fails to trip, the wiring can overheat and start a fire.
- Overloaded Circuits: Older panels may not be able to handle the electrical demands of modern homes.
- Corrosion and Wear: Over time, components within old panels can degrade, leading to unsafe conditions.
6. How to Upgrade or Replace Old Panels
Upgrading or replacing an old electrical panel is essential for safety and efficiency. Here are the key steps to take:
- Consult a Licensed Electrician: An electrician can assess whether your current panel meets safety standards and recommend replacements.
- Choose a Modern Electrical Panel: Brands like Siemens, Schneider Electric, and newer GE panels are popular for their safety features.
- Consider the Electrical Load: Ensure your new panel can handle the increased electrical demands of modern appliances and devices.
Q: Why are old electrical panels considered dangerous?
A: Old panels often do not meet modern safety standards. Brands like FPE and Zinsco are notorious for failing to trip, leading to fire hazards.
Q: Can I keep my old panel if it’s still working?
A: While some old panels may still function, it’s highly recommended to replace them due to the risks involved, especially if they are from high-risk brands like FPE or Zinsco.
Q: How do I know if my electrical panel needs replacement?
A: Look for signs like breakers that fail to trip, burn marks, frequent power outages, or an electrician’s assessment indicating safety issues.
Q: What is the cost of upgrading an old electrical panel?
A: Depending on the complexity, location, and brand, replacing an electrical panel can cost anywhere between $1,000 and $3,000
