Roy, Utah · Level 2 EV Charging
EV Charger Installation in Roy
In plain terms, this job means running a dedicated 240-volt circuit from your electrical panel to the spot where you park, mounting the charger, pulling the permit, and proving to the inspector that your panel can carry the new load.
Why a Level 2 charger needs an electrician at all
A new EV comes with a cord that plugs into a standard 120-volt outlet. It works, and it will slowly add a few miles of range per hour overnight. For a lot of Roy commuters driving to Ogden, Layton, or down to Salt Lake, that is not enough to refill what the day used.
A Level 2 charger runs on 240 volts, the same voltage as an electric range or dryer, and typically draws 32 to 48 amps continuously. That is the root of the problem: continuous load. Under the National Electrical Code, a circuit feeding an EV charger has to be sized at 125% of the charger's rating, because the car will pull that current for hours without a break.
So a 48-amp charger needs a 60-amp circuit, wire heavy enough to carry it, and — critically — enough spare capacity in your existing panel to give it away. That last part is where most Roy installs actually get decided.
Older homes on the west side of Roy and around the original Sunset-era subdivisions often still have 100-amp service. Newer builds off 1900 West and up toward the bench are usually 200-amp. The difference between those two determines whether this is a straightforward afternoon of work or a job that starts with a service upgrade.
What actually happens, step by step
No two garages are identical, but every code-compliant install in Roy moves through the same seven stages. Here is the honest version, including the parts nobody enjoys.
-
Load calculation on your existing panel
Before anyone quotes you a number, an electrician adds up what your home already demands — HVAC, water heater, range, dryer, everything — and compares it to your service size. This is a written calculation, not a guess, and the inspector will want to see it.
If the math leaves room for a 40- or 60-amp circuit, you are in the easy lane. If it doesn't, the conversation turns to load management or a panel upgrade before a single wire gets pulled.
-
Choosing where the charger lives
Charger placement is decided by your cord length, where the car's charge port sits, and how you back into the garage. Most cords are 18 to 25 feet, and you want slack — not a cable stretched tight across the floor.
Distance from the panel matters for cost too. Every extra foot of 6-gauge or 4-gauge copper between the panel and the charger adds material and labor, so a charger on the wall directly behind the panel is meaningfully cheaper than one on the far side of a two-car garage.
-
Pulling the permit with Roy City
An EV charger circuit is permitted work. A licensed electrician files the electrical permit, the job gets an inspection when it's finished, and the inspector signs off on the wire size, the breaker, the bonding, and the GFCI protection.
Homeowners sometimes ask whether they can skip this. You can't, not safely and not honestly — unpermitted 240-volt work is exactly the kind of thing that surfaces during a home sale or an insurance claim, and it is the single most common reason we get called out to redo someone else's install.
-
Running the circuit
In an unfinished garage, the conduit or cable runs along exposed framing and the job is clean. In a finished garage, or when the panel sits on the opposite side of the house, the run may go through the attic, under the crawlspace, or along the exterior — and that changes the labor hours more than any other single factor.
The breaker goes into the panel, the conductors are sized for the charger's continuous draw, and everything is torqued to spec. On a two-post or hardwired unit, the whip lands directly in the charger's junction box.
-
Hardwire or NEMA 14-50 outlet
You have a real choice here. A hardwired charger is the more robust option, supports higher amperage on most units, and removes the outlet as a point of failure. A NEMA 14-50 receptacle lets you unplug the unit and take it with you if you move, and lets you swap chargers without an electrician.
If you go the outlet route, insist on an industrial-grade receptacle. The cheap ones sold for RV hookups are not built for a car pulling 40 amps every night for years, and they are a known source of heat damage.
-
Mounting, commissioning, and app setup
The charger gets mounted at a sensible height, the amperage is configured in the unit to match the breaker it's on — a step that is skipped more often than you'd think — and it's connected to your Wi-Fi if it's a smart model.
Then it gets tested with the actual car. A charger that energizes but won't handshake with the vehicle is not a finished job.
-
Inspection and sign-off
The city inspector comes out, checks the work against the permit, and closes it. You keep the record. If your utility or a rebate program asks for proof of a permitted installation later, you have it.
What it costs in Roy — and what moves the number
Two homes on the same street can quote hundreds of dollars apart. The variable is almost never the charger; it's the panel and the distance.
| Scenario | Typical cost | What's driving it |
|---|---|---|
| Existing 200A panel, garage nearby | $800 – $1,800 | A standard Level 2 installation: short circuit run, spare panel capacity already available, permit and inspection included. |
| Panel upgrade required first | From $2,400 | The service or panel can't carry another continuous 40–60A load, so the panel is replaced or upsized before the charger circuit goes in. |
These ranges cover the electrical work. The charger itself is a separate purchase, and prices vary widely by brand and amperage. Long circuit runs, finished-wall fishing, exterior conduit, and detached garages all push the labor side of the estimate upward.
You may not need the panel upgrade
Before committing to a $2,400+ service upgrade, ask about load management. Many modern chargers can be configured to a lower continuous amperage, and some support a load-sharing device that throttles the car when the rest of the house is drawing heavily. A 32-amp charger on a 40-amp circuit still adds roughly 25 miles of range an hour — more than enough for a Roy-to-Salt-Lake commute — and it may fit in a panel that a 48-amp charger would not.
Signs your panel is going to be the problem
Your service is 100 amps. Check the main breaker at the top of your panel — the number is stamped on the handle. A 100-amp service with electric heat, an electric range, and a dryer has very little headroom left for a car.
There are no open slots. A double-pole breaker needs two adjacent spaces. If the panel is full, tandem breakers or a subpanel enter the picture, and not every panel is rated to accept them.
The panel is a known-bad brand. Federal Pacific Stab-Lok and Zinsco panels still turn up in older Utah homes. These are replaced, not added to — no reputable electrician will land a 60-amp EV circuit in one.
Breakers already trip when appliances stack up. If the dryer and the microwave together are enough to cause trouble, adding a car that pulls 40 amps for six hours straight is not going to end well.
Questions Roy homeowners actually ask
How long does the installation take?
A straightforward install with an existing 200A panel and a short run to the garage is usually a single day on site. Add a panel upgrade and it becomes a multi-day job, because the utility has to be involved to pull and reconnect the meter.
Can I install the charger myself?
The mounting, no. The 240-volt circuit, the breaker, and the permit, no — that's licensed electrical work in Utah, and it has to be inspected. Homeowners who wire their own EV circuits routinely undersize the conductors for continuous load, which is the exact failure that starts fires.
Do I need a 48-amp charger?
Probably not. Most drivers refill overnight from whatever the day depleted, and a 32- or 40-amp charger does that comfortably. Going to 48 amps means a 60-amp circuit, heavier wire, and a much higher bar for your panel to clear. Match the charger to your daily miles, not to the spec sheet.
What if my garage is detached?
Then you're running a feeder underground or overhead to the garage, likely with a small subpanel out there. It's routine work, but it's trenching and it costs more than a wall-mounted charger ten feet from the panel. Get that scoped before you buy the charger.
Will a charger work with my existing outlet in the garage?
The standard 120-volt outlets in a garage are on a shared circuit with the rest of the room, and they're not suitable for continuous EV charging. Even the 240-volt dryer outlet, if you have one, is on a circuit sized for a dryer's intermittent draw — not a car's six-hour pull. The charger gets its own dedicated circuit. There's no shortcut around that.
Start with the load calculation, not the charger
The single most useful thing you can do before buying anything is find out what your panel will actually support. That answer determines the charger you should buy, the amperage you should run, and whether $800 or $2,400 is the honest starting point for your home.
