The hidden hazard in your home: Outdated electrical panels

Behind the walls of many older homes sits a hardworking but aging electrical panel – part of a system that was never designed to handle today’s demand for big screen TVs, home offices, EV chargers and multiple appliances. As power needs grow, outdated panels can become overloaded, increasing the risk of overheating, tripped circuits, and electrical fires.

In 2021, there were nearly 30 residential fires per day on average in parts of Canada covered by the National Fire Information Database. Of those residential fires, approximately 10 percent were associated with mechanical or electrical failure or malfunction. Residential fires with electrical distribution equipment (wiring, extension cords, panels, etc.) accounted for about 11 percent of fires where cause was identified.

Clearly, upgrading a residential electrical panel isn’t just about convenience; it’s a proactive safety measure that protects families, preserves property, and brings a home’s electrical system up to modern standards. The team at The Shock Doctors agrees — and for February and March, they’re offering $500 off any new electrical panel installation.

As electricians evaluate older systems, they often find that even newer breaker panels can fall out of compliance with electrical codes. Many Canadian insurance companies will refuse coverage or increase premiums if a home still has an FPE or Zinsco panel, and several recurring issues tend to appear during inspections.

Common Panel Non-Compliance Issues:

• Missing Fillers: Open “knockouts” or holes in the panel face can expose live energized parts, creating a serious safety violation.
• Double‑Tapping: Two wires connected to a breaker designed for only one.
• Inaccessible Location: Panels must have clear working space (typically 1 metre in front) and cannot be installed in bathrooms or clothes closets.

Beyond code violations, certain older panel brands have well‑documented safety concerns that make replacement especially important.

Commonly Identified Unsafe or Hazardous Breaker Panels:

Federal Pacific Electric (FPE) Stab Lok

Independent testing has shown that many Stab Lok breakers fail to trip during overloads, allowing wires to overheat and increasing fire risk. Some breakers have even been found to remain energized when switched off, creating a hidden shock hazard.

Zinsco / Sylvania

Zinsco panels can suffer from breakers overheating and melting into the bus bar. When this occurs, the breaker can no longer trip, leaving circuits unprotected. In some cases, the bus bar corrodes or burns away entirely, causing arcing and potential ignition behind the panel.

Pushmatic (ITE Pushmatic)

Pushmatic panels use a push‑button mechanism instead of a traditional switch. Over time, these mechanisms often become stiff or fail to reset properly. With the design long out of production and replacement parts no longer manufactured, many electricians consider them unreliable and difficult to service safely.

Wadsworth

Wadsworth panels are also long discontinued, and certified breakers are no longer produced. Homeowners often rely on aftermarket components of questionable quality, which can compromise the panel’s ability to provide proper overload protection.

“Older systems using fuse boxes instead of circuit breakers can be more of a fire risk because they lack modern safety features,” said Scott Oliver, Master Electrician at The Shock Doctors. “A lot of the older panels are no longer being manufactured. Fuses can fail and old breakers may not trip during overloads. Now is a good time to consider the upgrade.”

Any new panel installation booked during the two‑month promotion will qualify for the $500 discount, whether the work is completed right away or scheduled for warmer weather. Oliver said homes built before the 1970s with older fuse panels can be under-equipped for modern electrical demand and more prone to overheating and fire risk. Older wiring and electrical systems make electrical fire risk higher because they weren’t designed for today’s power demand and lack modern safety features like arc-fault and ground-fault protection.

“Fuses aren’t inherently unsafe,” said Oliver. “They work just like circuit breakers (except they can’t be reset and must be replaced.) However, most fuse boxes in homes today are unsafe because they’ve been modified to try to serve today’s energy demands.”

Many fuse boxes become unsafe when people make well‑intentioned but improper modifications. Here are a few examples:

• Placing too many things on a single circuit. Because fuse boxes typically have fewer circuits, homeowners often end up plugging in too many electrical appliances to a single outlet. That leads to fuses that blow a lot, which can lead homeowners to replace a fuse with a bigger fuse.
• If you replace a 15-amp fuse with a 20-amp fuse (or larger), your fuse may stop blowing. However, you’ll also create a massive fire hazard. The wires in that circuit are only rated for 15-amps, not 20!
• Replacing the fuse with something metal. Some homeowners go a step further and insert a metal object (like a penny) where the blown fuse once was. Again, this eliminates blown fuses, but also completely removes the safety that fuses provide. Your wires could pull large amounts of electricity, overheat, and start a fire.

If you’re considering the upgrade, Oliver says the disruption is minimal. A team from The Shock Doctors will arrive on a scheduled date to complete the upgrade.

“An upgrade is completed in a day,” he said. “We coordinate with Hydro to shut off the power to the home, and we handle all permits with the Electrical Safety Authority. We also provide a Certificate of Inspection, for your records confirming that the work completed meets current ESA standards. All new panels come with a 25‑year warranty, and once the job is complete, Hydro returns to restore power.
