If your Calgary home was built between the 1950s and the mid-1980s and still has its original electrical panel, there is a reasonable chance it is a Federal Pacific or Stab-Lok unit. Both are worth knowing about before your next insurance renewal or home sale.
What Are Federal Pacific and Stab-Lok Panels?
Federal Pacific Electric (FPE) manufactured residential electrical panels under the Stab-Lok brand name from the 1950s through the 1980s. They were installed in large numbers across North America, including throughout Calgary and Alberta, during that period. The panels are identifiable by the brand name on the door and the distinctive red breaker handles inside.
These panels are no longer manufactured. The concern is not their age alone, it is a documented issue with how the breakers function. Independent testing and consumer safety investigations have found that Stab-Lok breakers can fail to trip under overload conditions. A breaker that does not trip when it should is not providing the protection it exists to provide.
Why Insurers Flag These Panels
Many Calgary home insurers either decline to cover properties with Federal Pacific Stab-Lok panels or apply a significant premium surcharge. This is not a blanket policy across all insurers, but it is common enough that it regularly comes up at renewal and at the point of sale.
If you are buying a home with one of these panels, your insurer will likely require replacement before binding coverage. If you already own the home, it is worth contacting your insurer directly to confirm your current coverage status. Some homeowners have discovered their policy was voided or subject to conditions they were not aware of.
Are These Panels Immediately Dangerous?
The honest answer is that most homes with these panels have been running without incident for decades. The risk is not that the panel will fail tomorrow, it is that the protection mechanism may not function correctly under the specific condition it was designed for. That is a different category of risk than an actively failing panel, but it is a legitimate one that warrants replacement.
We do not use fear to sell panel upgrades. If you have one of these panels and your home is functioning normally, you have time to plan the replacement properly. What we would not recommend is deferring it indefinitely or adding significant new electrical load to a panel of this type.
How to Identify a Stab-Lok or Federal Pacific Panel
Look for the following:
- The name Federal Pacific Electric or FPE on the panel door or inside the box
- The Stab-Lok name on the breakers themselves
- Red breaker handles, which are characteristic of this brand
- A panel installed in a home built between approximately 1955 and 1985
If you are unsure, a licensed electrician can identify the panel in a few minutes. Do not rely solely on a home inspection report — inspectors note the presence of these panels but are not electricians and do not assess the full scope of the issue.
What Does Replacement Involve?
Replacing a Federal Pacific or Stab-Lok panel in Calgary involves the following:
- A City of Calgary electrical permit
- Removal of the existing panel and installation of a new one by a licensed electrician under Master Electrician oversight
- ENMAX coordination to disconnect and reconnect the service
- A City of Calgary electrical inspection
In most cases the existing service entrance and wiring can remain in place and only the panel cabinet and breakers are replaced. If the incoming service is still 100 amp and you want to upgrade to 200 amp at the same time, that is worth doing as a combined project to avoid a second round of permits and ENMAX coordination costs.
What Does a Panel Replacement Cost in Calgary?
| Service Type | Price Range | Notes |
|---|---|---|
| 100 amp panel replacement | $3,000 to $3,500 | Replacing the panel cabinet only where incoming service is already adequate |
| 200 amp overhead service upgrade | $4,000 to $6,000 | Full upgrade including new panel, service entrance, ENMAX coordination, permit and inspection |
| 200 amp underground service upgrade | $7,000 to $10,000 | Underground conduit and service lateral. Common in newer Calgary neighbourhoods and infills |
All Panel Upgrade Experts jobs include City of Calgary permit, inspection coordination, and ENMAX service reconnection. Our panels pass City of Calgary inspection first time, every time.
What About Home Sales?
A Federal Pacific or Stab-Lok panel will appear in any competent buyer’s home inspection report. In a Calgary real estate transaction this typically becomes a condition of sale, a price negotiation point, or a requirement from the buyer’s insurer. Replacing the panel before listing removes that variable and can prevent a deal from falling apart late in the process.
If you are purchasing a home with one of these panels, factor replacement cost into your offer and budget for it in the first year of ownership.

Frequently Asked Questions
Is a Federal Pacific Stab-Lok panel dangerous?
The documented concern is that Stab-Lok breakers can fail to trip under overload conditions. Most homes with these panels have operated without incident for decades, but the protection mechanism may not function correctly when it is needed. Replacement is the appropriate course of action.
Will my insurer cancel my policy if I have a Stab-Lok panel?
Policies vary by insurer. Many Calgary insurers flag these panels at renewal or at the point of sale and require replacement as a condition of coverage. Contact your insurer directly to confirm your current status.
Can I just replace the breakers instead of the whole panel?
Replacement breakers compatible with Stab-Lok panels are not readily available and this approach does not resolve the underlying concern. Full panel replacement is the correct fix.
Do I need to upgrade to 200 amp at the same time?
Not necessarily, but if your home is on 100 amp service it is worth doing both at once. The cost difference is modest and you avoid a second round of permits and ENMAX coordination down the road.
How long does panel replacement take?
Most replacements are completed in a single day. The work requires a power outage of roughly four to six hours.
Do you serve areas outside Calgary?
Yes. We serve Cochrane, Okotoks, and Chestermere in addition to Calgary.
