Is My Electrical Panel Safe? A Los Angeles Homeowner Guide
Many LA homes still run on panels installed between the 1950s and the 1980s. Some of those brands have a poor track record, and many were never sized for EV chargers, heat pumps, induction ranges or ADUs. Here's how to tell whether yours is a problem, and what replacing it involves.
Written by Amir Shnitzer, owner of Powerhouse Electric. Los Angeles electrical contractor since 1992.
If you have a Zinsco, Federal Pacific Stab-Lok or Pushmatic panel, plan to replace it. If you have a fuse box, have it looked at. For anything else, condition and capacity matter more than age. Not sure what you have? Text us a photo.
How do I know if my electrical panel is unsafe?
Watch for these signs:
- The panel door or cover feels warm or hot to the touch
- A burning or hot-plastic smell near the panel
- Buzzing, crackling or sizzling sounds
- Scorch marks, melted plastic or discoloration around breakers
- Breakers that trip often, or won't reset
- Lights that dim or flicker when the AC, dryer or microwave starts
- Rust or water stains inside the panel door
- A panel type on the list below
If you see smoke or flames, leave the house and call 911. For anything else on this list, don't remove the panel's inner cover yourself. Take a photo of the outside and call an electrician.
How do I find out what brand of panel I have?
Open the panel door (the outer door only). The brand name is usually printed on a label inside the door or on the metal cover around the breakers. Look for names like Zinsco, Sylvania, Federal Pacific, FPE, Stab-Lok, Pushmatic, Bulldog or Challenger.
If the label is gone or unreadable, a photo of the breakers is often enough for an electrician to identify the brand.
Which panels need a closer look?
Zinsco (also sold as Sylvania)
Zinsco panels were common in Southern California homes built from the 1950s to the 1970s. The known problem: breakers can overheat at the point where they connect to the panel and, in the worst cases, fail to trip. Original Zinsco breakers haven't been made in decades, and replacement parts are hard to find.
Our recommendation: replace
Federal Pacific (FPE) Stab-Lok
FPE Stab-Lok panels were installed in many homes from the 1950s into the 1980s. Their breakers have a long history of failing to trip under overload in testing. A breaker that doesn't trip doesn't protect the wiring.
Our recommendation: replace
Pushmatic (Bulldog, later ITE)
Pushmatic panels use push-button breakers instead of standard switches. They're no longer made, replacement breakers are hard to find, and the breakers can stiffen with age. In our experience, a Pushmatic panel almost always needs replacement.
Our recommendation: replace
Fuse boxes
A fuse box isn't unsafe by itself. The problems are usually how it's been used: a larger fuse screwed in to stop a circuit from blowing, too little capacity (often 60 amps) for modern loads, and no room to add circuits. Some insurance carriers also ask about fuse boxes.
Usually due for an upgrade
Challenger
Some Challenger equipment has been flagged by insurance carriers, but full replacement isn't always the answer. If your carrier has flagged a Challenger panel or switchboard, see our panel insurance non-renewal page.
See the Challenger pageMy panel is old, but it's not one of those brands. Do I need to replace it?
Not because of age alone. A 40-year-old panel from a sound brand, in good condition, can keep working. What matters is:
- Condition: corrosion, heat damage, loose or damaged breakers
- Capacity: whether the panel and service can carry what you run now, and what you plan to add
- Space: whether there's room for new circuits without doubling up wires on one breaker
- Parts: whether listed replacement breakers are still made for it
Do I need a 200-amp service upgrade?
Many older LA homes have a 60-amp or 100-amp service. That was plenty for lights and a refrigerator. It often isn't enough for central AC, an EV charger, a heat pump, an induction range, a pool, an ADU, or solar with battery storage.
The way to know is a load calculation under the California Electrical Code (Article 220). It adds up what your home actually draws and what you plan to add. Sometimes the answer is a 200-amp upgrade. Sometimes a load-management device lets you add an EV charger or a heat pump without one.
Can I add an EV charger to my existing panel?
Sometimes. A Level 2 charger needs its own dedicated circuit, and your panel needs both the capacity and the space for it. If the load calculation says your service is too small, you have two options: upgrade the service, or install a load-management device that shares power between the charger and the rest of the house.
What's the difference between a panel replacement, a service upgrade and a subpanel?
| Job | What it means | When you need it |
|---|---|---|
| Panel replacement | New panel, same service size | The panel is a problem brand, damaged, or out of space |
| Service upgrade | Bigger service from the utility (for example, 100A to 200A), usually with a new panel and meter equipment | The load calculation says you need more power |
| Subpanel | A second, smaller panel fed from the main one | You need circuits in a garage, ADU or addition. It adds space, not capacity |
Who is my utility, and why does it matter?
Depending on where you live, your power comes from LADWP, SCE, or your city's own utility (Burbank, Glendale and Pasadena run their own).
A panel replacement at the same size usually needs only a short disconnect and reconnect. A service upgrade is different: the utility decides where the new meter goes and what it requires before it will connect a bigger service. This step is called a meter spot. Utility scheduling is often the longest part of an upgrade, so it's worth starting early.
Do I need a permit to replace an electrical panel?
Yes. In the City of Los Angeles, panel replacements and service upgrades are permitted and inspected by LADBS (the Los Angeles Department of Building and Safety). Beverly Hills, Santa Monica, West Hollywood, Culver City, Pasadena and other cities have their own building departments. The utility makes its final connection after the city inspection passes. If your home already has power, you won't be left without it while you wait: we put the house back on power the same day.
Unpermitted panel work can cause problems later, when you sell the house or file an insurance claim. Keep the permit and the final sign-off with your house records.
How long does a panel replacement take?
Most panel replacements take more than a day from start to finish. The power is off for part of one day: up to a full workday (6 to 8 hours), and usually less. The longer part is the paperwork around it: the permit, the city inspection and, for a service upgrade, the utility's meter spot and scheduling.
Will my insurance company care about my panel?
Some carriers ask about panel brand and age when they write or renew a policy, and some flag certain brands. If you've received a letter from your carrier about your panel, see our panel insurance non-renewal page.
What affects the price of a panel replacement?
Every house is different, which is why we start from photos. The main things that move the number:
- Panel replacement only, or a service upgrade too
- Where the panel is (outside wall, inside a closet, recessed in stucco)
- Whether the utility requires new conduit, a new meter location or trenching
- The condition of the wiring coming into the panel
- Grounding and other updates the current code requires when a panel is replaced
- Stucco, drywall or paint work around the panel

- Your electric meter
- A wider shot showing where the panel is
