You just picked up a new Tesla — or you’ve got a delivery date circled on the calendar — and the first real question hits you: *can my garage panel handle an EV charger?* That’s exactly what  means in practice, and the answer depends on a few specific things inside your electrical system that are worth understanding before anyone starts pulling wire. We’ve walked through this assessment in homes all across , and the situation is almost never as simple as “just add a breaker.”

## What a Level 2 Charger Actually Demands From Your Panel

A Level 2 charger — the kind that adds 20 to 30 miles of range per hour and is the standard for home use — runs on 240 volts and typically requires a dedicated 40- to 60-amp circuit. That’s not a small ask. A [Wallbox or comparable EV charger installation](https://fhrelectric.com/wallbox-ev-charger-installation-what-the-job-looks-like-from-panel-to-plug/) means running a new circuit from your main panel all the way out to the garage, which could be 30 to 80 feet of conduit and wire depending on how your home is laid out.

Here’s what that pull looks like in real numbers: a 48-amp charger on a 60-amp circuit draws continuous load at 80% of breaker capacity — exactly where the NEC wants it. If your panel is already managing a newer HVAC system, a kitchen remodel, and a pool pump (very common in North Scottsdale), that headroom disappears fast.

## The Three Things We Check Before We Quote Any EV Install

- **Total service size.** Is your home on 100-amp or 200-amp service? Older homes in the Arcadia and McCormick Ranch corridors are sometimes still on 100-amp panels. A 60-amp EV circuit on a loaded 100-amp service is a real problem. Check out our breakdown on [whether 200-amp service is still enough for a modern Arizona home](https://fhrelectric.com/is-200-amp-service-still-enough-for-a-modern-arizona-home/) — spoiler: it depends on what else is running.
- **Available breaker slots and capacity.** A full panel with no open slots isn’t just inconvenient — it often means double-tapping, which is a genuine hazard. If you’ve never heard the term, read up on [what a double-tapped breaker is and why it’s not a minor issue](https://fhrelectric.com/what-a-double-tapped-breaker-is-and-why-its-not-a-minor-issue/). We see it constantly during EV pre-assessments.
- **Panel age and brand.** A 30-year-old panel isn’t automatically dangerous, but certain brands are. If you’re in a home built in the late ’70s through early ’90s anywhere from Gilbert to Fountain Hills, there’s a real chance you have a Zinsco, Federal Pacific, or Challenger panel. [These brands are red flags](https://fhrelectric.com/zinsco-pushmatic-and-challenger-panels-why-these-brands-are-red-flags/) — not just for an EV charger, but for your home overall.

## What Does an EV Charger Installation Actually Cost in ?

Straightforward installs — good panel, open slot, short run to the garage — tend to fall in the $400–$900 range for labor and materials, not counting the charger unit itself. Add panel upgrades, long conduit runs, permit fees (required in  for this work), and that number climbs. A full panel upgrade with EV circuit can run $2,500–$5,000+ depending on scope. We give straight prices upfront, not estimates that balloon after the drywall opens.

If you’re a homeowner who has been burned by surprise invoices before, you’re not alone — it’s the most common complaint we hear from people in  who called us after a bad experience with someone unlicensed. Speaking of which: [the real risks of hiring an unlicensed electrician in Arizona](https://fhrelectric.com/the-real-risks-of-hiring-an-unlicensed-electrician-in-arizona/) are worth understanding before you get another low bid.

## How We Confirm Your Panel Can Handle It — Before We Start

We don’t guess. Every EV charger job starts with a load calculation and a visual inspection of the panel. On jobs where something feels off — a breaker that runs warm, a panel that’s seen some age — we use thermal imaging to check for hotspots inside the box that a visual inspection simply cannot catch. That diagnostic step is something most one-truck operations skip entirely. It’s one reason we do things the way we do. [See what thermal imaging actually finds inside walls](https://fhrelectric.com/what-thermal-imaging-finds-inside-your-walls-that-a-visual-inspection-misses/) that nobody else is looking for.

If your panel needs an upgrade first, we handle the full scope — permit pulled, APS coordination, inspection scheduled — so you’re not managing three different contractors. That’s the advantage of working with a team that has a full construction background, not just an electrical license.

Whether you’re in a newer build near DC Ranch, a mid-century home closer to Old Town Scottsdale, or anywhere across Maricopa County, the process is the same: assess, plan, price, permit, install, inspect. Done right, once.
