EV Charging

Charging is a capacity problem before it is a charger problem

People arrive at EV charging with a product question and a deadline. Which charger, and how fast can it go in. The answer to both is usually determined by something they have not looked at: the electrical panel.

A charger is a large, sustained load. Unlike a dryer that runs for an hour, it can draw near its rated current for hours at a stretch. That is treated differently in a load calculation, and it is why a charger is one of the two additions that most often reveals a property has run out of electrical headroom. The other is a standby generator.

Level 1 and Level 2

Level 1 is a standard 120-volt outlet. It needs no new equipment and it is slow. For a short commute and an overnight window it can genuinely be enough, and it is worth saying so rather than selling past it.

Level 2 runs on 240 volts and is what most people mean by installing a charger. It needs a dedicated circuit, and that circuit is where the planning happens.

Within Level 2, actual speed is limited by whichever is smallest: the circuit, the charging equipment, or the vehicle's own onboard charger. Installing a larger circuit than the vehicle can use buys nothing today, though it can be reasonable if you expect to change vehicles. Worth deciding deliberately rather than defaulting to the largest option on the shelf.

What this covers

• EV Charger Installation for home charging: the dedicated circuit, the run, and code-aware wiring.
• Commercial & Multi-Family EV Charging for workplaces, retail, and shared-parking properties, where the questions are about load sharing and access rather than one car.
• EV Charger Repair & Upgrades for equipment that has failed, or a charger that no longer suits the vehicle it is serving.

The run matters as much as the panel

Two properties with identical panels can produce very different quotes based on one thing: the distance from panel to parking, and what sits between them. A charger on the other side of an attached garage wall is a short job. One at a detached structure across a property involves trenching or conduit and becomes a different project.

Measuring that distance before asking for a rough number is the single most useful thing you can do.

When the panel cannot carry it

A panel upgrade is one path and it is not the only one. Load management devices can let a charger share existing capacity by throttling or pausing when other large loads are active. Choosing a lower-amperage charger is another, and for many households the difference in overnight charge is not meaningful.

Which approach makes sense depends on the property, the vehicle, and how you actually drive. That is worth assessing before buying hardware, not after.

Permits, and why they matter here

EV charger circuits are permitted work across San Diego County jurisdictions. Beyond compliance, a permitted and inspected installation is a documented one, which matters at resale and for warranty questions on the vehicle side.

Charging and standby power together

If you are considering both a charger and standby generator power, handle the panel conversation once rather than twice. Both depend on the same capacity, both may require the same upgrade, and scoping them together is consistently cheaper than discovering the constraint in the middle of the second project.

What installation actually involves

The physical work is usually the shortest part. Assessment, permitting, and inspection account for most of the elapsed time, and the run from panel to parking accounts for most of the variation in cost.

A typical home installation means a dedicated breaker at the panel, a conductor run sized for the load and the distance, and the charger mounted and commissioned. Where that run passes through finished space, or leaves the building, the job grows.

We test the installation under real charging conditions before leaving rather than energising it and assuming. Charging faults have a habit of appearing under sustained load rather than at switch-on.

Multi-vehicle households

Two vehicles is increasingly the question rather than one, and it changes the arithmetic. The options are a second dedicated circuit, which needs the capacity to support it, or equipment designed to share one circuit between two positions.

Sharing is often the better answer. Two vehicles rarely both need a full charge on the same night, and shared equipment costs considerably less than a second circuit plus the panel work that frequently comes with it. Whether it suits you depends on how much range each vehicle actually uses in a day.

Thinking one step ahead

The cheapest capacity is the capacity you install while the walls are already open and the trench is already dug. If a second vehicle is plausible within a few years, or you expect to replace the current one with something that charges faster, it is worth sizing the circuit and the conduit for that now.

This is the one place where we will suggest spending slightly more than today's requirement, because the alternative is repeating the same work later at full cost.

Older properties

Much of the housing stock across East County was built long before anyone was charging a car at home. A 100-amp service that comfortably runs the property as it is used today can have very little headroom left for a sustained load of this size.

That is not a barrier so much as a decision point: upgrade the service, manage the load, or accept a slower charge. All three are legitimate, and which is right depends on the property and how you drive rather than on which one is easiest to sell.

Getting started

Tell us the vehicle, where it parks relative to the panel, and roughly how old the property is. Those three answers cover most of the assessment before anyone is on site.
