Electrical panels and service upgrades.
Most panel calls in Sacramento start with something tripped, something warm, or something new that needs power. Each points to a different job — a breaker repair, a panel replacement, or a service upgrade.
Panel replacement, repair, or a service upgrade
A panel replacement, a breaker repair, and a service upgrade are three different jobs. Which one you need comes down to the panel's condition and the load you want it to carry.
Circuit breaker repair
A breaker that trips on the same circuit, one dead outlet, or a switch that buzzes — and the rest of the house is fine. The problem is usually downstream, not the panel itself. A sound panel does not need replacing because something it feeds failed.
Circuit breaker repairElectrical panel replacement
Heat marks, rust, a burnt smell at the panel, breakers that will not reset, a damaged bus, or equipment that is no longer supported. The panel is replaced because of its own condition — not because of what you want to plug in.
Panel replacementElectrical panel upgrade
A charger, a heat pump, an induction range, an addition, or an ADU. Nothing is broken. The question is whether the service can carry the new load — and the answer can be no. A 200-amp increase is not automatic.
Panel upgrade
How panel work is told apart from a service upgrade
Panel and service are two different things, and most calls turn on which one is short. The equipment on the wall and the load it carries are separate questions.
-
A damaged panel is not automatically more amps
Heat, a compromised bus, or equipment nobody makes breakers for is a condition finding. If the service rating still fits the house, that is a replacement of the panel at the same size — not an increase.
-
More capacity is a service upgrade
When the house genuinely needs more than the service can carry, that is a service upgrade — a different job from swapping a panel, and one that can involve the utility and the meter, not just the box on the wall.
-
A full panel can still have capacity
Running out of breaker spaces is not the same as running out of amps. A service with headroom but nowhere to land new circuits is a subpanel, which adds spaces without touching the service.
-
The panel rating is not the service size
A panel stamped for 200 amps does not mean 200 amps of service behind it. The main breaker, the meter, and the conductors decide what the service actually is — the number on the box is only what the enclosure is rated to hold.
-
A load calculation decides, not the label
Whether the service is short is a calculation of what is connected against what is planned — not a reading of the number on the panel. It is why the answer to "do I need 200 amps" can be no, and why it is worked out at the property rather than over the phone.

Electrical panel questions
How do I know if my panel needs repair or full replacement?
If one circuit trips and the rest of the house is fine, the problem is usually downstream of the panel — a breaker or circuit repair, not the panel. The panel itself comes out when its own condition is the problem: heat marks, a damaged bus, or equipment nobody makes trustworthy breakers for. It is judged on the wall, not from a description.
My panel is full. Do I need a bigger service?
Not necessarily. Running out of breaker spaces is not the same as running out of amps. If the service has headroom but nowhere to land new circuits, a subpanel adds spaces without touching the service. An upgrade is only needed when the load itself exceeds what the service can carry.
Do I need a 200-amp upgrade for an EV charger or a heat pump?
Sometimes, and a load calculation decides — not the number stamped on the panel. It weighs what is already connected against what you are adding. The answer to "do I need 200 amps" is often no, and where capacity is the only issue, load management can sometimes keep a charger on the existing service. See the 100 vs 200 amp guide.
Can you quote a panel replacement from a photo?
A photo tells us the brand and roughly what we are looking at, which is a useful start. It does not settle the price — the service rating, the condition of the bus, grounding, and what the permit and utility require are worked out on site. We put the number in writing after that, not before.
Does panel work need a permit?
Panel and service work generally does, and for many service changes the utility has to disconnect and reconnect. A permit with a signed-off inspection is also frequently what an insurer or a buyer in escrow actually wants on record. We confirm the path for the address before the work is agreed.
Is a Federal Pacific or Zinsco panel an automatic replacement?
No. The equipment history is a good reason to have it examined, not a verdict. What decides replacement is the condition on the wall and whether the panel can still be added to safely — the same test as any panel. If an insurer named the brand in a letter, insurance corrections is where that starts.
Are a breaker box and an electrical panel the same?
People call it a breaker box. That is the panel: the bus, the breakers, and the cover.
