Federal Pacific (FPE) Panel: What It Means on Your Home Inspection Report

When a report names "Federal Pacific Electric," "FPE," or "Stab-Lok," the inspector identified the brand of your electrical panel or its circuit breakers. Federal Pacific Electric made Stab-Lok residential breakers and the panels they plug into. InterNACHI, one of the home inspector associations, lists the labels inspectors look for: Federal Electric, Federal Pacific Electric, Federal NOARC, Federal Pioneer, FPE, FPE-Stab-Lok, and Stab-Lok.

A breaker's job is to shut off the current when a circuit draws more than its wiring should carry, before the wire overheats. The question about FPE breakers is whether they reliably do that, and the official record on it is narrower than their reputation. Here is exactly what it says, and who can evaluate your panel.

Why It Matters

In June 1980, Reliance Electric, FPE's parent company, reported to the CPSC that many FPE circuit breakers did not fully comply with Underwriters Laboratories (UL) requirements. The CPSC's investigation focused primarily on two-pole residential breakers made before Reliance acquired FPE in 1979, and its testing confirmed that these breakers fail certain UL calibration tests. Those tests check whether a breaker holds the current it's rated for and trips within set time limits when an overload pushes the current past its rating.

In March 1983, the CPSC closed the investigation without a recall. It said it was concerned about the failures but unable at that time to link them to the development of a hazardous situation, that the data available didn't establish a serious risk of injury, and that, given its limited budget, it would not commit further resources to such a costly investigation. Reliance's position was that the breakers trip reliably at most overload levels unless they've been operated in a repetitive, abusive way; CPSC staff said they had insufficient data to accept or refute it. The release, revised in 2011, now carries a note from CPSC staff asking electricians, homeowners, home inspectors, and real estate agents to read it carefully: the Commission closed the matter without determining whether FPE breakers are safe.

So why did your inspector flag it? InterNACHI tells inspectors that FPE panels have a reputation for being problematic and that further evaluation by a qualified electrician is recommended. Its panelboard guidance goes further, citing a general consensus among electricians that these panels have significant safety issues and breakers that fail to trip at rates far higher than industry standards; it recommends replacement and notes there are no recalls. It doesn't cite a source, and it isn't a regulator's finding.

We rate it monitor because no official body has established a hazard. That isn't a clean bill of health: a breaker that may not trip on an overload deserves an electrician's look before you close. It moves up to safety with any of the warning signs in the CPSC's Guide to Home Wiring Hazards, which dates from around 2000: breakers that need resetting often, switch plates or outlet covers that are hot to the touch or discolored, the smell of hot insulation, sizzling or buzzing, sparks, flickering lights, or any shock, even a mild tingle.

What to Do Before Closing

• Ask the inspector for specifics: photos, which label they read, whether it's the main panel or a subpanel, and whether they saw scorching, heat damage, or breakers that wouldn't stay on. The InterNACHI Standards of Practice, one of the standards inspectors work under, don't require inspectors to remove panel covers or operate breakers, so ask what they did and didn't check.
• Have a licensed electrician evaluate the panel and put the recommendation in writing. The CPSC's own advice in its 1983 release: "When in doubt, consult a licensed electrician."
• Ask your insurer whether the panel affects your policy; a home inspection doesn't determine insurability, per the InterNACHI Standards of Practice.
• Talk to your real estate agent about asking the seller to repair, replace, or give a credit for it within your inspection contingency, using the electrician's written findings.

What to Do After You Move In

If the panel stays, follow the electrician's recommendation, and use the safety advice the CPSC gave with its 1983 release, which applies to any panel: know which circuit feeds what, never overload a circuit, be particularly careful not to connect several high-current products such as heaters to a low-amperage circuit, and when a breaker trips, find out why instead of simply resetting it. Our breaker guide walks through a safe reset, and our first 30 days guide shows how to map circuits; on this panel, you can ask the electrician to do it.

For any warning sign above, stop using that outlet or switch, keep your hands off the panel, and call an electrician promptly. And make sure your smoke alarms work; our smoke and CO alarm guide covers what to install.

Can You Fix It Yourself?

No. Evaluating the panel and replacing its breakers or the panel itself are inside-the-panel work for a licensed electrician. The CPSC tells homeowners not to remove the panel cover, and our DIY vs. hire-a-pro guide puts anything inside the main panel on its red list. What you can do is read the brand from the labels on the door or face of the panel, without removing any cover, and list what each circuit feeds for the electrician.

Frequently Asked Questions

Was there a Federal Pacific panel recall?

Not by the CPSC. It closed its investigation of FPE Stab-Lok breakers in 1983 without a recall and without deciding whether they are safe, and InterNACHI's guidance for inspectors says there are no recalls on these panels. You'll find other claims about FPE online; this page sticks to what we could read in a primary source.

Is a Federal Pacific panel a deal breaker?

Not automatically. It's a question for a licensed electrician, whose written findings you can bring to your agent when you discuss a repair, a replacement, or a credit. Other panel findings, such as a double-tapped breaker, add to that list; see more findings in our inspection report decoder.

The Bottom Line

An FPE or Stab-Lok panel is a flag for an electrician, not a verdict. The CPSC confirmed in the early 1980s that some FPE breakers failed UL calibration tests, then closed its investigation in 1983 without a recall and without a safety determination. Get the inspector's photos, have a licensed electrician evaluate the panel and put the recommendation in writing, and raise it with your agent before your contingency ends. Never open the panel yourself, and treat heat, a hot-insulation smell, buzzing, or sparks as urgent.
