Electrical Panel Upgrades, Permitted and Inspected
Replacing a Zinsco or Pushmatic panel, or moving from 100 amps to 200 amps so your house can actually run what you want to plug into it. One written price that includes the permit, the SDG&E coordination, and the inspection.
How to tell your panel is the problem
Most panels get replaced for one of two reasons: the equipment itself is a known hazard, or the house has outgrown the service. Some of these you can see from the garage. Some of them only show up when you try to add something.
- Breakers that trip when two normal things run at once
- Push-button breakers instead of toggle switches
- A fuse box, or a panel with screw-in fuses
- The label reads Zinsco, Sylvania-Zinsco, Pushmatic, Bulldog, ITE, Challenger, Federal Pacific or Stab-Lok
- Scorch marks, rust, a burning smell, or a warm panel cover
- Lights that dim when the AC or the dryer kicks on
- No open breaker spaces left, or double-tapped breakers
- An insurer or home inspector flagged the panel in writing
- You were told your panel can't take an EV charger, battery, or ADU
The panels we replace most around here
North County housing stock tells you a lot before we open the door. 1950s and 60s tract homes tend to have Pushmatic. 1970s homes tend to have Zinsco. They fail differently, and both are worth knowing about.
Zinsco / Sylvania-Zinsco
The most common problem panel in this part of San Diego County, mostly in homes built in the 1970s. The documented failure mode is a breaker that can fail to trip on an overload while looking and feeling completely normal from the outside — the panel gives you no warning, because from your side nothing appears wrong. Bus bars also corrode and overheat where the breakers clip on.
Pushmatic / Bulldog / ITE
Push-button breakers instead of toggle switches — that's the tell from across the garage. Common in San Diego homes built before the 1980s. The problem here is less about dramatic failure and more about obsolescence: the push-button mechanism wears out, many have no main shutoff, most are only 60 to 100 amps, and they can't accept the AFCI and GFCI breakers current code requires. Replacement breakers aren't manufactured anymore, so a repair usually isn't a real option.
Federal Pacific Stab-Lok and Challenger
Both show up here, though less often than Zinsco or Pushmatic — Federal Pacific was more heavily installed elsewhere in the country. Stab-Lok breakers have a long-documented failure-to-trip record, and certain Challenger production runs have been subject to safety notices and recalls. If either name is on your panel, it's worth an inspection.
Insurance and selling the house
Carriers in California increasingly flag these panels at renewal or on a new policy, and some ask for replacement documentation before they'll write the house. If you've had a letter, bring the inspection report or the carrier's notice when we come out — what they usually want to see is a permit and a signed-off inspection, which is exactly what you get at the end.

California SB 382 and the 2026 electrical disclosure
If you're selling a house in California you may have run into this, and it's being described online as bigger than it is. Here's what the statute actually says.
What the law requires
SB 382 (Becker) was signed in September 2024 and added Section 1102.6i to the California Civil Code. For sales on or after January 1, 2026, the seller or the seller's agent delivers the buyer a written notice advising that it may be advisable to have a qualified professional inspect the building's electrical systems — including the main service panel, subpanels and wiring — and noting that substandard, recalled or faulty wiring may create a fire risk and may make property insurance harder to obtain.
What it does not require
It does not name Zinsco, Pushmatic, Federal Pacific or any other brand. It does not require you to get an inspection. It does not require you to replace your panel. It's a notice, and the statute has exceptions — your agent can tell you whether your particular sale is one of them.
What it means in practice
Every buyer of a California home now reads a line, handed to them by the state, telling them that faulty wiring can make insurance hard to get — at the exact moment they're deciding what to ask the seller for. Panels that used to go unmentioned now get asked about.
If you're listing an older North County home, the cheap move is knowing what's in your panel before the buyer's inspector tells you. If it's fine, you say so with confidence. If it isn't, you decide how to handle it on your schedule instead of during escrow.

What the price covers
One number, written down before we start. Panel upgrades are quoted from an on-site look, never over the phone — the meter, the service entrance, the grounding, and the wall behind the panel all change the job.
- Load calculation on your actual panel, not a rule of thumb
- Permit filed with your city or county
- SDG&E coordination and disconnect scheduling
- New service panel and breakers, code-current equipment
- Grounding and bonding brought up to current code
- Service entrance conductors and mast where required
- Final inspection scheduled and met
- Circuit directory labeled legibly, panel left clean

Online in under a minute, or by phone. Roughly an hour on site.
We look, then price it
A certified electrician inspects the panel, the service, and the grounding, and you get a firm written price. If your panel doesn't need replacing, we'll tell you that.
Permit and utility
We file the permit and coordinate the SDG&E disconnect so the outage lands on a day you've agreed to.
Install and inspection
Most residential panel replacements are a one-day install. We meet the inspector and hand you the signed-off paperwork.
What 200 amps actually buys you
Capacity isn't the point on its own. It's what it lets you add without redoing the service a second time.
EV charging
A Level 2 charger draws real current. On a full 100-amp panel it's often the upgrade that makes the charger possible at all. See home & EV.
Battery backup
Powerwall and similar systems need the room and the correct interconnection. Doing the panel first avoids paying twice.
Heat pumps and induction
Electrifying an AC system, water heater, or range adds substantial load to a service that was sized for a 1970s house.
ADU or addition
A new subpanel for an ADU almost always starts with whether the main service can carry it.
Selling the house
A flagged panel becomes a negotiating point at inspection. Handling it beforehand keeps it out of the buyer's column.
Just running the house
If two appliances can't run at once today, that's a capacity problem, and it doesn't resolve itself.
What homeowners say
"Very knowledgeable, professional, communicative, accommodating, and reliable. They did an excellent job in replacing and upgrading out [our] electrical panel and getting the required permits."
"On time, on target, best quote hands down, totally professional. Its hard to find a company like this now a days."
Straight answers
How much does an electrical panel upgrade cost?
It depends on the service size, whether the meter and service entrance are being replaced, the panel location, and what your city requires. We don't quote panels over the phone, because the number would be a guess. The on-site estimate is free and the written price is the price you pay.
Do I need a permit to replace an electrical panel?
Yes. A service panel replacement is permitted work in every city we serve, and it gets inspected. We file the permit and meet the inspector. Unpermitted panel work tends to surface later at exactly the wrong moment — an insurance claim or a home sale.
Why replace a Zinsco or Pushmatic panel that still works?
Two different answers. With Zinsco, the documented failure mode is a breaker that doesn't trip when it should, and a panel doing that looks completely normal until it matters. With Pushmatic, the panel may work fine and still be a dead end — no parts made, no room for the AFCI and GFCI breakers code now requires, and usually not enough service to add anything. On top of both, insurers have started treating these panels as a condition of coverage, which is often what prompts the call.
How long does it take, and how long is the power off?
Most residential panel replacements are a one-day install. The power is off for the working portion of that day, coordinated with SDG&E so you know the date in advance. We'll tell you the realistic window when we quote it.
Do I need a full upgrade, or just more breaker spaces?
Sometimes a subpanel solves it, and sometimes the existing service genuinely has room. That's a load calculation, not an opinion. If you don't need the upgrade, we'd rather tell you that than sell you one.
What if I just want something diagnosed first?
That's a service visit, which is $249 — a certified electrician comes out and the first 30 minutes of diagnosis is included. You get an exact flat price before any work begins, and the full $249 comes off the job if you approve it. Panel upgrade estimates are separate and free.
Does California SB 382 mean I have to replace my panel before I sell?
No. SB 382 added Civil Code Section 1102.6i, and for sales on or after January 1, 2026 it requires the seller or their agent to give the buyer a written notice advising that an inspection of the electrical system may be advisable and that substandard, recalled or faulty wiring can create a fire risk and complicate insurance. It names no brands, requires no inspection, and requires no replacement. It does make buyers far more likely to ask. This is general information, not legal advice.
