Home charging is one of the best parts of owning an electric vehicle—when the electrical side is planned correctly. A Level 2 charger is a real load on your panel, and the path from the breaker to the charging location matters as much as the charger itself. This guide covers what Cascadia Power does for an EV charger hookup, how Level 1 and Level 2 differ, when a panel upgrade enters the conversation, and what helps before you schedule a visit.
What the electrician does (and what we don’t)
Getting a home charger working usually involves more than one piece. Here’s the split:
- You (or your dealer) choose and buy the charger unit—or use the one that came with the vehicle—and decide where you want to park and charge. Most EV chargers come with a 25′ cord, so that limits how far away from where you normally park your vehicle you can install the charger.
- Your electrician confirms the panel can support the load, runs a dedicated circuit, installs the disconnect or outlet the charger needs, provides the required ground-fault protection, mounts or terminates at the charger location, and makes sure the work is permitted and inspectable.
Cascadia Power does the electrical hookup. We don’t sell charger brands, and we don’t work on the car. Knowing that up front keeps expectations clear: you pick the equipment; we get power to it the right way.
Level 1 vs Level 2 (in plain terms)
You’ll hear two common home-charging labels:
- Level 1. Plugs into a standard 120-volt household outlet. Slow overnight top-ups. Fine for some drivers with short daily miles; not ideal if you need a fuller charge every morning.
- Level 2. Uses a dedicated 240-volt circuit—similar in spirit to a dryer or hot tub circuit. Much faster home charging. This is what most homeowners mean when they say “install an EV charger.”
Exact amp ratings vary by charger and vehicle (common dedicated circuits are in the 40–60 amp range, sized to the manufacturer’s instructions and code). We size the breaker and wire to the charger’s requirements and local rules—not to a guess from a product photo.
Panel capacity and the dedicated circuit
A Level 2 charger needs its own circuit. That usually means a two-pole breaker in your panel and a run of cable or conduit out to the charger location. Before we commit to that path, we look at whether the panel has:
- Space. Two adjacent slots for a two-pole breaker (or another code-compliant way to serve the load).
- Capacity. Enough service ampacity for the charger plus everything else the house already runs—heat pump, range, dryer, hot tub, shop tools, and so on.
Electricians call that second check a load calculation. It’s how we confirm the home can handle the new continuous load without overloading the service. Sometimes the answer is a straightforward dedicated circuit. Sometimes a subpanel helps. Sometimes a panel change-out (or a larger service) is the cleaner long-term fix—especially on older 100-amp panels that are already full.
On a site visit we look at the open panel, the proposed charger location, and the route between them. Then we can say what the hookup involves and whether anything else needs to happen first.
Where to put it: garage, outdoor, and distance
Most homeowners mount a Level 2 charger in the garage or on an exterior wall near where the car parks. A few placement points matter more than brand logos:
- Distance from the panel. Longer runs cost more in materials and labor. Finished walls, crawlspaces, and exterior conduit all change the path.
- Indoor vs outdoor rating. Outdoor or damp locations need equipment and wiring methods rated for that exposure.
- Cable reach and parking. The charger should sit where the cord reaches the car’s charge port without stretching across a walkway every night.
- Access for service. Leave clear working space at the panel and at any required disconnect.
If you already know which stall or driveway spot you’ll use, tell us. Photos of the panel and the wall where you want the charger go a long way toward an early sense of the job.
Permits, inspection, and protection
EV charger circuits are permitted electrical work in all jurisdictions across Southwest Washington and Oregon. Cascadia Power pulls the permit, does the install, and coordinates inspection. That keeps the work documented for you, your insurer, and anyone who buys your home later.
A few terms you’ll hear in plain language:
- Dedicated circuit. Power that only serves the charger (or the receptacle the charger plugs into). Other outlets shouldn’t share it.
- GFCI / ground-fault protection. Protection that trips if current leaks where it shouldn’t. Required for EVSE circuits under current code in most cases—often at the breaker, depending on the charger and installation method.
- Disconnect. A way to shut power off near the equipment for service. Whether a separate disconnect is required depends on the charger design and local interpretation; hardwired units and plug-in units are treated a little differently.
How we keep install day focused
Most EV charger hookups don’t require a whole-house shutdown the way a panel change-out does. Still, time in your garage or driveway matters—especially if you’re juggling work-from-home, kids, or a second vehicle.
After planning, we stage materials and do as much prep as practical ahead of time—confirming breaker type, wire, mounting hardware, and the route—so the on-site visit stays focused on the install itself. That approach comes from over a decade of electrical prefabrication and shop-prep experience: solving the layout before we’re standing in your garage. When a panel upgrade is part of the same project, we plan that window carefully too so essential loads aren’t down longer than they need to be.
What helps before you call
Three details make estimating faster:
- Which charger (or amp rating). Model name, brochure, or the electrical label—whatever shows the circuit size the manufacturer calls for.
- Where it will mount. Garage wall, exterior wall, or carport—and roughly how far from the panel.
- What the panel looks like. A clear photo of the open panel door (breakers and any empty slots) will help us understand what materials to bring.
If the car is already in the driveway and you’re living on Level 1 for now, tell us. We’ll help you plan the Level 2 hookup so you’re not waiting longer than you need to.
On-site estimates for install work are free. (Our $295 visit applies to troubleshooting calls—not to planning a charger hookup.)
