Panel & Service Work
Start With the Load Calculation, Not the Panel
Most people arrive at electrical panel upgrades in Salinas the same way: breakers tripping, no spaces left, or an EV charger and a heat pump on the shopping list. The right answer to that is not always a bigger panel. Sometimes it is a subpanel, sometimes an added branch circuit, and sometimes it is a full service upgrade. Which one applies comes out of a load calculation and a look at the existing conditions.
We do panel and service work for homes and businesses in Salinas, Monterey, Carmel, Pebble Beach, Pacific Grove, Seaside, Marina, and the surrounding Monterey County communities. That range matters here, because a 1950s Peninsula cottage, a Salinas Valley ranch property with a well pump, and a commercial building downtown each present a different set of constraints.

Which One Do You Need
An Upgrade, or Something Smaller?
These are general patterns rather than rules. What applies to your property depends on the calculated load, the condition of the existing equipment, the utility service, and the adopted code in your jurisdiction. Still, this is roughly how these conversations tend to go.
Your situation
Often the direction
Panel is full but the service has calculated headroom
Subpanel, or an added branch circuit
Adding a garage, workshop, or ADU
Subpanel fed from the existing service, subject to load calculation
Breakers trip under ordinary daily use
Diagnosis first. May be a circuit issue rather than a service issue
Adding an EV charger and a heat pump
Load calculation. May point to a service upgrade, load management, or a reduced-amperage circuit
Fuse box rather than breakers
Panel replacement is commonly warranted after evaluation
Federal Pacific Stab-Lok or Zinsco equipment
Evaluation, with replacement commonly recommended
Selling or refinancing
Worth evaluating early, since inspectors and insurers often flag older equipment
If the calculation points to a full service upgrade, our 200 amp panel upgrade page covers that path in detail. If it points somewhere smaller, we will say so.
Warning Signs
Signs Your Panel Is Worth Evaluating
None of these on their own confirm that electrical panel upgrades are required. They are reasons to have the equipment evaluated.
- No open breaker spaces, or tandem breakers filling the gaps
- A fuse box, or a panel that has been added onto over the years
- Federal Pacific Stab-Lok or Zinsco equipment
- Breakers that trip under ordinary daily use
- Rust, moisture, corrosion, or heat discoloration inside the enclosure
- Plans for an EV charger, heat pump, ADU, hot tub, or shop
- Lights that dim noticeably when a motor or compressor starts
- Buzzing, warmth at the cover, or a burning odor near the panel
Service Sizes and What They Generally Carry
When people ask about electrical panel upgrades, service size is usually the first thing they mention. It is one input, not the whole answer. Two homes with the same service can have very different available capacity depending on what is already connected.
Service size
Commonly seen with
Typical constraint
100 amp
Smaller and older homes, often with gas appliances
Limited headroom once electrification is added
125 to 150 amp
Mid-size homes, some added circuits over time
Workable for partial electrification, depending on calculated load
200 amp
Current residential standard in new work
Often supports EV, heat pump, and range together, subject to calculation
400 amp
Larger properties, main plus ADU, multiple HVAC systems
Usually driven by calculated load rather than preference

Schedule an Electrical Panel Upgrade Assessment
Call 831-272-4229 and we will evaluate the existing equipment, run the load calculation, and give you a written scope with the options laid out. We work seven days a week across Salinas and the Monterey Peninsula.
Subpanel Installation
Subpanels have become one of the more common alternatives to full electrical panel upgrades, largely because homeowners are adding square footage, workshops, and EV charging to properties whose panels ran out of room years ago.
A subpanel adds breaker spaces and puts circuits closer to where they are used, which matters for a detached garage or an ADU at the back of a lot. It is worth being clear about what it does not do: a subpanel does not add capacity to the service feeding it. Where the calculated load already sits near the limit of the existing service, a subpanel moves the problem rather than solving it.
Done properly, the work involves feeder sizing based on the calculated load, a four-wire feeder with the neutral and equipment grounding conductor kept separate at the subpanel, its own grounding electrode where required for a detached structure, and disconnecting means as the adopted code requires. Common applications include garages, workshops, pool and spa equipment, ADUs, and additions.
Smart Electrical Panels
Smart panels replace conventional equipment with breakers that can be monitored and, on many systems, controlled. You get consumption data per circuit and the ability to schedule or shed loads from an app.
The interesting capability is load management. Where the equipment is listed for it and the adopted code and utility allow, managing loads can sometimes let an existing service carry an EV charger or a battery system that a straight calculation would not otherwise support. Whether that applies to a given installation depends on the equipment, the calculated load, and the AHJ, so it is worth evaluating rather than assuming.
Smart panels cost more than conventional equipment, so we would rather you choose one for a specific reason, such as solar and battery integration or a capacity constraint, than for the feature list. We will tell you honestly when a conventional panel does the same job for less.
Older and Obsolete Equipment
Two categories get discussed together and should not be. Federal Pacific Stab-Lok and Zinsco equipment has a documented history of breakers failing to trip under fault conditions, and many insurers and home inspectors flag them specifically. Replacement is commonly recommended after evaluation.
Separately, there is a broad group of older panels that are simply obsolete: discontinued lines where listed replacement breakers are difficult or impossible to source, or equipment that has corroded, been modified, or run past its service life. That is a serviceability and condition question rather than the same failure history, and it gets assessed case by case. An older panel is not automatically a hazard, and we will not tell you it is in order to sell a replacement.
What Drives the Cost
Electrical panel upgrades vary widely in price for reasons that are not obvious from the outside. These are the factors that actually move the number:
- Scope. A panel swap on a sound service is a different job from a full service change with new conductors, mast, and meter socket.
- Panel location. Distance from the meter, and whether the panel is being relocated, drives both labor and material.
- Existing conditions. Whether the branch wiring, grounding, and bonding can be reused as found, or need correction.
- Equipment selected. Conventional versus smart panels, and any surge or load management devices.
- Jurisdiction. Permit fees and utility requirements vary across Monterey County.
You get a written itemized scope before scheduling, and Wisetack financing is available if you would rather spread it out.
Permits, Inspections, and the Utility
Electrical panel upgrades generally require a permit and inspection when they involve main service equipment, and the sequencing catches people out. The permit needs to be open before the work, the inspection has to pass afterward, and PG&E typically will not release the meter until that has happened.
Requirements and turnaround vary across jurisdictions, which matters when a project sits in Carmel rather than Salinas. We pull the applicable permits, schedule and attend the inspections, and coordinate the utility disconnect and reconnect so the three do not fall out of order. You receive the signed documentation at completion, which is what an insurer or a buyer's agent will eventually ask for.
Power During the Work
The service has to be de-energized while electrical panel upgrades are performed. How long depends on the scope and, often more than that, on the utility scheduling window rather than the labor itself. We give you the realistic range at the assessment rather than an optimistic one.
Where site conditions and equipment capacity allow, temporary backup power for selected essential loads can be arranged on an as-needed basis. It is not a life safety system and should not be relied on for medical equipment. If anyone in the building depends on powered medical equipment, please keep an independent backup plan in place and tell us when you schedule so we can plan around it.

Common Questions
FAQs About Electrical Panel Upgrades
Do I need a panel upgrade or just a subpanel?
It depends on what is actually constrained. If the panel is out of breaker spaces but the service itself has capacity based on a load calculation, a subpanel is often the more economical answer. If the calculated load is approaching or exceeding what the service can carry, adding a subpanel does not solve that and a service upgrade is generally the right path. Existing conditions matter too, including the age and condition of the equipment, the service entrance, and the meter. We evaluate all of it before recommending either one.
How do I know what size panel I need?
Panel size should follow a load calculation on your actual equipment rather than a rule of thumb or the square footage of the house. The calculation accounts for existing loads, planned additions such as an EV charger or heat pump, and how those loads behave together. In some cases the result supports a 200 amp service. In others a smaller service with load management, or simply an added branch circuit, meets the need at lower cost.
Can a subpanel let me add an EV charger without a service upgrade?
Sometimes, and it comes down to the load calculation rather than the panel itself. A subpanel provides breaker spaces, but it does not add capacity to the service feeding it. Where the calculated load leaves room, a subpanel or an added circuit may be all that is required. Where it does not, options can include a reduced-amperage charger circuit, a listed load management device, or a service upgrade, depending on existing conditions and what the adopted code and the utility allow.
Will my power be off during a panel upgrade?
The service has to be de-energized while the work is performed, and the duration depends on the scope and on utility scheduling. Where conditions and equipment capacity allow, temporary backup power for selected essential loads can be arranged on an as-needed basis. It is not a life safety system and should not be relied on for medical equipment, so if you depend on powered medical equipment please keep an independent backup plan in place and tell us when you schedule.
Do I need a permit for a panel upgrade?
In most cases, yes. Work on main service equipment generally requires an electrical permit and inspection, though requirements and process vary by jurisdiction. Utility coordination is usually part of it as well, since PG&E typically has to disconnect before the work and release the meter after the inspection passes. We pull the applicable permits, schedule and attend the inspections, and coordinate the utility side so the sequence does not fall out of order.
My panel is a Federal Pacific or Zinsco. Is it really a problem?
Federal Pacific Stab-Lok and Zinsco equipment has a documented history of breakers failing to trip under fault conditions, and many insurers and home inspectors flag them specifically. Replacement is commonly recommended after evaluation. Other older panels are a different conversation. Some are simply obsolete or difficult to source listed breakers for, which is a serviceability concern rather than the same failure history, and those are assessed on condition case by case.
What is a smart panel and is it worth it?
A smart panel adds circuit-level monitoring and controllable breakers, so you can see consumption per circuit and, on many systems, shed or schedule loads automatically. That last capability is the practical reason people choose them, because managing loads can sometimes let a service support an EV charger or battery system that it otherwise could not. Whether that applies to your installation depends on the load calculation, the equipment selected, and what the adopted code and the utility permit. Smart panels cost more than conventional equipment, so it is worth deciding based on a specific goal rather than the feature list.
