EV Charging & Load Calculation in Los Angeles — Do You Really Need a Panel Upgrade?
Planning Level 2 EV charger installation in LA? Don’t jump straight to a 200A panel upgrade. At Farashi Electric, we start with a professional load calculation to see if your existing service can safely handle EV charging. Sometimes a tidy sub-panel upgrade or managed charging solves it; when you truly need a panel upgrade Los Angeles, we handle the permit & inspection and complete most upgrades in 1 day after approval.
Why load calculation comes before hardware choices
An EV charger is just one more load—albeit a chunky one. Without a load calculation, you’re guessing: you might overspend on a full service change or under-spec the circuit and trip breakers. We evaluate real-world demand in your home (HVAC, range, dryer, future circuits) and size the EV circuit—and your panel strategy—accordingly.
What you get from Farashi Electric:
- A clear, code-compliant plan based on NEC + local AHJ requirements
- The shortest, safest path to charging (no unnecessary work)
- A documented scope for permit & inspection the first time
Step-by-step: how Farashi Electric evaluates your EV charging
- Discovery call (5–10 min) — EV model, daily mileage, parking location, existing symptoms (trips, flicker), and any remodel plans.
- On-site assessment — We check breaker spaces, panel condition, grounding/bonding, meter-main arrangement, sub-panels, and conduit routes.
- Professional load calculation — We account for present and near-term loads (kitchen upgrades, mini-splits, workshop tools) and your EV charging habits.
- Right-size the solution — From a dedicated Level-2 circuit to managed charging, sub-panel upgrade, or a 200A service only when warranted.
- Permit & inspection — We file with your AHJ (e.g., LADBS) and schedule inspection; you get labeled circuits and a clean, documented install.

Level-2 options
- NEMA 14-50 receptacle (plug-in Level-2): Flexible and popular. Needs correct conductor, breaker sizing, and GFCI/AFCI where required. Great for many homeowners who value device portability.
- Hardwired Level-2 charger (e.g., wall connector): Cleaner look, often higher continuous rating and better cable management. Excellent when you want a dedicated, permanent solution.
- Managed charging / current limiting: Your charger or energy management device can cap current so you charge overnight without overloading the panel. This often avoids full service upgrades.
- Sub-panel near the parking area: Reduces long conduit runs, organizes present/future circuits (gate opener, lights, tools), and keeps the main panel neat.

Do I need 200 amps for an EV?
Not always. The answer lives in your load calculation, not a rule of thumb. Many homes charge reliably on a correctly sized circuit or with managed charging. When your calculation shows you’re at the limit—or you’re planning multiple EVs or heavy electrification—then a main service/panel upgrade becomes smart. Final approval always comes from your local AHJ.
Safety & code points most owners miss
- Continuous load & conductor sizing: EV charging is a long, steady draw; wiring/breakers must match the continuous rating—not just a momentary peak.
- GFCI/AFCI nuances: Depending on circuit location and device, protection requirements apply. We design to code and to your actual layout.
- Clearances & working space: Chargers near panels, water sources, or vehicles require careful placement; inspectors check this.
- Labeling matters: A fully labeled panel isn’t cosmetic; it speeds inspections, future maintenance, and emergency shutoffs.
Where a sub-panel shines (and saves)
If the main is crowded or far from the garage/driveway, a sub-panel upgrade near the parking spot keeps runs short, future-proofs for tools/outlets/lighting, and keeps your main panel tidy. It also prevents overfilling the main with tandem breakers that can confuse standby loads and inspectors.

If you’re looking at EVs, heat pumps, induction cooking, or even a future ADU, an EV charging load calculation in Los Angeles is your chance to get a clear, engineered roadmap instead of guessing your way through upgrades. With Farashi Electric, we look at your actual lifestyle—daily driving, existing loads, and future plans—then show you whether a dedicated EV circuit, managed charging, a sub-panel, or a full 200A upgrade truly makes sense.

FAQs
We don’t recommend it. Permits/inspections protect your home and insurance; we handle them for you.
No. Many homes pass the load calculation. We only recommend 200A panel upgrade when it’s truly justified.
It depends on usage, placement, and panel capacity. We’ll design the circuit that fits your home and future plans.
For EV-only installs, outages are minimal. If a panel upgrade is needed, we aim for a same-day cut-over after permit approval.
Yes—see Level 2 EV charger installation for options and prep.
Yes. We can configure current limits and explain how/when to use them to stay within capacity while meeting your daily driving needs.
