The question that decides your price
Do you have the capacity?
A load calculation accounts for your property's existing demand — heating, cooling, cooking, water heating, laundry — and determines how much headroom remains. Panel space and service capacity are separate issues; you can have one without the other.
- Lower the charger's amperage Most chargers can be configured to draw less. A 32-amp install still adds substantial range overnight, and may fit within your existing service comfortably. For many households this costs nothing extra and is entirely sufficient.
- Install load management Equipment that monitors household demand and throttles or pauses charging when the rest of the property is drawing heavily — then charges at full rate when it isn't. Frequently a fraction of the cost of a service upgrade. Ask about it before agreeing to one.
- Upgrade the service Genuinely necessary sometimes — particularly with electric heating, two EVs, or a service already at its limit. But it should be the conclusion of a calculation, not the opening recommendation.
We'll show you the numbers and which of these applies. A company that never mentions load management isn't looking after you.
Briefly
Level 1, Level 2, and what belongs at home
For almost everyone the question is which Level 2 setup, not which level.
Worth addressing directly
Why not just use an existing outlet?
Four shortcuts that circulate
- The old dryer outlet in the garage. Different receptacle configurations, often on a circuit sized for intermittent use rather than hours of continuous draw, and frequently without the grounding arrangement current requirements expect. EV charging is a sustained load — that's the important difference.
- Extension cords. Not for EV charging. Sustained current through an undersized or coiled cord generates heat, and this is a genuinely common source of incidents.
- Sharing a circuit. EV charging is treated as a continuous load and generally requires its own dedicated circuit.
- Unpermitted DIY installs. Beyond the safety question, an uninspected 240-volt circuit is a problem at resale, potentially an insurance issue, and can disqualify you from rebates that require permitted installation.
The correct install isn't complicated. It's just not something to improvise around.
Connection type
Hardwired or plug-in?
Both are legitimate. The trade-offs are real.
Our general steer: hardwired for outdoor and higher-amperage installs, plug-in where flexibility matters and the amperage suits it. We'll tell you which fits your setup rather than defaulting.
Position
Where it goes — and what that costs
- Attached garage, panel on a shared wall. The cheapest scenario. Short run, easy mounting, protected from weather.
- Attached garage, panel elsewhere in the house. Cable run through walls, ceilings, or basement. Distance and access drive the cost.
- Outdoors — driveway or carport. Requires weather-rated equipment and mounting, and often a hardwired connection. Trenching may be involved if the run crosses open ground.
- Detached garage or outbuilding. The most involved residential case. If there's no existing feeder, one has to be run — often underground — and a subpanel is frequently the sensible approach, particularly if you want lighting and outlets there too.
- Condo, townhouse, or shared parking. Technically feasible, but usually the constraint is permission and shared infrastructure rather than electrical work. Expect to involve the strata, HOA, or building management, and expect load management to be part of the conversation.
Where you park matters as much as where the panel is. Charger cables have finite length, and mounting the unit where the cable comfortably reaches your charge port is worth planning rather than discovering.
Why Bar Nunn calls us
What you get when you call Summit
We check capacity before recommending equipment
The load calculation comes first. Everything else follows from it, including whether you need a service upgrade at all.
We'll mention load management
Because it often saves a customer several thousand dollars, and a company that never brings it up isn't looking after you.
Permitted and inspected
EV circuits are permitted, inspected work. We handle the permit, coordinate the inspection, and hand you the documentation — which matters for rebates, insurance, and resale.

How it works
What the installation involves
-
Assessment and load calculation
Capacity, panel space, and the run.
-
Permit
Applied for and issued before work starts.
-
Circuit installation
Conductors sized for the charger's rating. Because EV charging is a continuous load, circuits are generally sized above the charger's rated current rather than matched to it — which is why a 40-amp charger typically needs a 50-amp circuit.
-
Cable routing and mounting
Through walls, ceilings, conduit, or underground depending on the path — then mounted at a height and position where the cable reaches comfortably and the unit is protected.
-
Termination and commissioning
Connection, configuration of the charger's amperage setting to match the circuit, and testing.
-
Inspection and handover
Inspection coordinated with the authority having jurisdiction, then documentation plus a walkthrough of the charger's settings and app if it has one.
Most straightforward installs are completed in a day. Detached buildings, trenching, and panel work extend that.
Paperwork
Permits, rebates, and documentation
Permits are required for EV circuits in essentially every jurisdiction, and inspection follows. This isn't optional and it isn't a formality — an unpermitted 240-volt circuit is a liability at resale and potentially with your insurer.
Rebates and incentives exist in many areas, offered by utilities, municipalities, and higher levels of government. Availability, amounts, and conditions change frequently, so check what currently applies where you are before assuming. Two things are worth knowing: many programs require a permitted installation by a licensed electrician, and several require the paperwork to be submitted within a window after installation.
Keep your permit, inspection sign-off, and invoice together. Between rebates, insurance, and eventual resale, that paperwork gets asked for more than you'd expect.
Planning ahead
Worth doing now rather than later
If the walls are open or the trench is dug, marginal cost is low.
- Size the circuit for the charger you might want, not just the one you're buying. Conductor cost is a small share of the job; revisiting the run is not.
- Run conduit for a second charger if a second EV is plausible. Empty conduit is cheap insurance.
- Consider a subpanel at a detached garage rather than a single circuit — it costs little more at the time and gives you lighting, outlets, and future capacity.
- Think about where you'll actually park, including whether you might reverse in one day and nose in another. Cable reach is a daily annoyance if it's wrong.
- Ask about capacity for other electrification — a heat pump, induction cooking — while the load calculation is being done anyway.
Commercial
Commercial and multi-unit charging
We install charging for workplaces, fleet depots, retail and hospitality parking, and multi-unit residential buildings across Bar Nunn.
Commercial installations bring considerations residential ones don't: multiple charge points sharing a supply, networked chargers with access control and payment, usage reporting, accessibility requirements for parking, and lighting and signage around the bays. Fleet applications add scheduling and depot load profiles.
Multi-unit residential is usually as much a governance problem as an electrical one — shared infrastructure, cost allocation between residents, metering, and board approval. Load management is almost always central, since supplying every stall at full capacity is rarely practical or necessary.
We'll assess demand, phasing, and what the building can support, and stage installations where it makes sense to build capacity over time.
Pricing
What affects the cost
- Distance from panel to charger — the single biggest variable in most residential jobs.
- Capacity — whether you need nothing, load management, a subpanel, or a service upgrade.
- Hardwired or receptacle — including GFCI requirements on receptacle installs.
- Charger amperage — higher ratings need larger conductors and breakers.
- Route and construction — finished walls, concrete, and underground runs cost more than open framing.
- Detached buildings — feeders, trenching, and often a subpanel.
- Outdoor rating and mounting — weather-rated equipment and pedestals where there's no wall.
- Permits and inspection — required, and variable by jurisdiction.

Questions
Frequently asked questions
Do I need to upgrade my electrical service?
Often not. Lowering the charger's amperage or installing load management lets many homes charge without touching the service. A load calculation tells you which applies — ask about all three options before agreeing to an upgrade.
What is load management?
Equipment that monitors household demand and throttles or pauses charging when the rest of the property is drawing heavily. It lets you add charging within existing capacity and often costs far less than a service upgrade.
What size charger should I buy?
Check what your vehicle can accept first — a 48-amp charger won't charge a car limited to 32 amps any faster. Then match that against what your service supports.
How much does EV charger installation cost in Bar Nunn?
Mostly driven by distance from the panel and whether your service has capacity. You'll get one written quote covering circuit, run, permit, and inspection.
Can I just plug into my dryer outlet?
Not advisable. Configurations differ, the circuit may be sized for intermittent rather than continuous use, and the grounding arrangement often isn't what current requirements expect. EV charging is a sustained load.
Can I use an extension cord?
No. Sustained current through an extension cord generates heat and is a known source of incidents.
Should I get hardwired or plug-in?
Hardwired for outdoor and higher-amperage installs and generally the more robust connection. Plug-in for flexibility, though receptacle installs typically require GFCI protection. We'll advise on your specifics.
How long does installation take?
Most straightforward installs are a day. Detached garages, trenching, and panel work take longer.
Do I need a permit?
Yes. EV circuits are permitted, inspected work everywhere we operate, and many rebate programs require permitted installation by a licensed electrician.
Are there rebates available?
Often, from utilities and various levels of government — but availability and conditions change frequently, so check what currently applies in your area. Most require permitted installation and timely paperwork.
Can you install a charger at a detached garage?
Yes. If there's no existing feeder, one has to be run — often underground — and a subpanel is frequently the better approach if you want lighting and outlets there too.
I live in a condo. Is it possible?
Usually yes electrically, but the constraint is normally shared infrastructure and board approval rather than the wiring. Load management is typically part of the solution.
Can you install two chargers?
Yes, often with shared capacity so both can charge without doubling your demand. If a second EV is a possibility, it's worth planning for now.
Get the capacity answer first
The charger you buy matters far less than whether your service supports it and how far it sits from your panel. Those two answers set the price — and if capacity is tight, there are cheaper routes than a service upgrade that not everyone will mention.
