Do You Need to Upgrade a 100 Amp Panel for a Level 2 EV Charger in Calgary?

Do You Need to Upgrade a 100 Amp Panel for a Level 2 EV Charger in Calgary?

The Question We Get Every Week

We get asked this question every week. You buy a vehicle. You want a Level 2 EV charger installation in Calgary
at your home. Then someone says, “Wait, you only have 100 amp service.” Now you’re wondering if you need to upgrade your panel.

The honest answer is that sometimes you do. Sometimes you do not. It really depends on your house.

Let us walk through it the way we explain it to our customers.

Why 100 Amp Service Used to Work (and Why It’s Tight Now)

Years ago, 100 amp service was completely normal. It handled your lights, appliances, a dryer, and a range. Fast forward to 2026 and most homes now have air conditioning, electric ranges and dryers, basement developments, hot tubs, home offices, and now electric vehicle chargers.

How Much Power a Level 2 Charger Pulls

A Level 2 electric vehicle charger usually draws 32 to 48 amps. Because electric vehicle charging is considered a continuous load, it counts heavier in your load calculation. That is where 100 amp panels start running out of room.

Calgary Permits and Inspections: What Inspectors Focus On

When we install an electric vehicle charger in Calgary, a permit is required. That means it will be inspected. Inspectors are very focused on total service demand, accurate load calculations, proper breaker sizing, and whether your panel can safely handle the added load. If you have 100 amp service, expect the question: “Has a load calculation been done?” Because if your service is already near its limit, they will not approve the installation without a solution.

Load Calculations: The Part You Can’t Guess

A load calculation is not a guess. It is not “it should be fine.” It is a breakdown of your square footage, heating type, appliances, existing electrical loads, continuous loads like electric vehicle charging, and total service capacity. Sometimes the numbers work. Sometimes they are too close for comfort. This is where most homeowners are surprised.

Two Options When Your 100 Amp Panel Is Maxed Out

If your 100 amp panel is maxed out, you have two options.

Option 1: Upgrade to 200 Amp Service

Option 1 is to upgrade to 200 amp service. This gives you room for electric vehicle charging, future upgrades, heat pumps, air conditioning, and basement suites. It involves a new panel, utility coordination, possible service changes, and a higher upfront cost. For some homes it makes sense long-term.

Option 2: Install a Load Management Device

Option 2 is to install a load management device. This is becoming very common in Calgary. A load shedding device monitors your home’s power use. If your house starts pulling too much power, it temporarily pauses the electric vehicle charger. When demand drops, it turns the charger back on automatically. You do not notice it. Your car still charges overnight. In 100 amp homes, this allows us to install an electric vehicle charger without upgrading to 200 amp service. Inspectors are very familiar with these now.

When 100 Amp Service Is More Likely to Be Fine

You are more likely to be okay if you have gas heat, gas hot water, no central air conditioning, no hot tub, and no large electric heating loads. In those situations, we often find there is room. We do not assume. We calculate.

Do You Need a Permit for an EV Charger in Calgary?

Do you need a permit for an electric vehicle charger in Calgary? Yes. It requires a permit and an inspection, and you should expect a load calculation to be part of the process. Skipping the permit is not worth it. It can create problems with resale, insurance, and safety.

Bottom Line

The bottom line is that a 100 amp panel can sometimes handle an electric vehicle charger. Not always. The only way to know is to look at the panel, run the numbers, and decide whether you need load management or a service upgrade. We are seeing electrification every year in Calgary. Planning your service capacity properly now saves you from changes later. If you are thinking about installing an electric vehicle charger, it is always better to assess your panel before booking the installation.

The 2026 Guide to Electrical Permits and Inspections in Calgary

The 2026 Guide to Electrical Permits and Inspections in Calgary

If you’re adding an electric vehicle charger, installing air conditioning, upgrading your panel, wiring a hot tub, or finishing a basement, you’ll have to deal with a City of Calgary electrical permit and inspection.

In 2026, electrical inspections are especially focused on one thing: service capacity. With more EV chargers and higher electrical demand in homes, inspectors are paying closer attention to load calculations and electrical panel limits.

Here’s how the process actually works, and how to avoid headaches with your permit and inspection.

Step 1: Pulling an Electrical Permit in Calgary

Most electrical projects require a permit in Calgary.

You’ll need one for things like:

Small repairs like swapping a light fixture usually don’t require an electrical permit. But if you’re running new wiring or adding load to the electrical system, you probably do.

As a homeowner, you can pull an electrical permit for work in your primary residence. That said, most people prefer having a licensed electrician handle it, especially for anything involving service upgrades or high-load electrical equipment.

Step 2: Booking the Inspection

Once the electrical work is complete, the inspection gets booked.

In Calgary, inspections aren’t scheduled to the hour. They’re booked into one of two windows:

  • Morning: 8:00 a.m. to 12:00 p.m.

  • Afternoon: 12:00 p.m. to 4:30 p.m.

You’ll find out the day of whether you’re on the morning or afternoon list.

Inspectors are busy and cover a lot of ground every day. If the work isn’t ready, they move on. A re-inspection fee can apply.

Before booking, make sure:

  • The job is fully complete

  • The electrical panel is accessible

  • Breakers are installed and labeled

  • Someone 18+ is on site during the inspection window

Preparation makes a big difference.

What Inspectors Are Really Looking For in 2026

The big focus right now is load demand.

With EV chargers, air conditioning, electric heating, and basement suites becoming more common, homes are pulling more power than ever.

A lot of Calgary homes still have 100 amp service. That used to be fine. Today, it can get tight.

If you’re adding a high-load device like:

  • An electric vehicle charger

  • Air conditioning

  • A hot tub

  • Electric heat

There’s a good chance a load calculation will be required.

Load Calculations: Why They Matter

A load calculation determines whether your existing electrical service can safely handle the added demand.

It looks at things like:

  • Existing appliances

  • Heating equipment

  • Range and dryer loads

  • Equipment demand

  • Continuous vs non-continuous loads

  • Total electrical service capacity

If the numbers are too close to your panel limit, the inspector may not sign off until it’s addressed. This is where a lot of homeowners get surprised.

If Your Electrical Service Is Maxed Out: Two Options

If your service is at its limit, you typically have two options.

Option 1: Upgrade the Electrical Service

Upgrading from 100A to 200A increases capacity, but usually involves:

  • Replacing the panel

  • Utility coordination

  • Possible mast upgrades

  • Higher cost overall

Option 2: Install a Load Shedding Device

In many cases, a load management device is a practical solution.

It monitors real-time electrical usage and temporarily reduces power to non-essential loads (like an EV charger) if the house is nearing its electrical limit. When demand drops, it restores power automatically.

In 2026, these devices are becoming more common, especially for EV chargers in homes with 100A service. They often allow you to pass inspection without a full service upgrade.

Common Reasons Electrical Inspections Do Not Pass

Failed electrical inspections are avoidable. The usual issues are:

  • No load calculation when one is required

  • Improper breaker sizing

  • Incomplete panel labeling

  • Clearance issues around the panel

  • Bonding and grounding problems

  • Adding high-demand equipment without verifying service capacity

It usually comes down to planning ahead.

How to Make It Go Smoothly

If you want your inspection to pass the first time:

  • Pull the correct permit before starting

  • Make sure the work is completely finished before booking

  • Verify service capacity before installing high-load equipment

  • Have load calculations ready if needed

  • Keep access clear and safe

Electrical inspections aren’t meant to slow projects down. They’re there to make sure everything is safe and up to code. If the prep work is done properly, the inspection is usually straightforward.

Final Thoughts

Electrical permits and inspections in Calgary aren’t complicated, but they are getting stricter around service demand.

With more electrification happening in homes, inspectors are focused on:

  • Electrical service capacity

  • Load calculations

  • Proper breaker sizing

  • Code-compliant electrical installations

Planning electrical upgrades in Calgary is a lot smoother when you know what the City is going to look for. Get a quote from Crew Electrical Services before you start. We’ll confirm your service capacity, let you know if a load calculation is needed, and give you a clear plan for the permit and inspection so there are no surprises.

Electrical Panel Upgrade Calgary: Surge Protection That Saves Your Investment

Electrical Panel Upgrade Calgary: Surge Protection That Saves Your Investment

Surge protection is one of the smartest additions to any electrical panel upgrade Calgary homeowners plan. In Calgary, AB, power fluctuations and lightning can quietly damage appliances and electronics. Crew Electrical Services is licensed and insured, and we make sure your electrical panel and services upgrade protects what matters most.

Protecting Your Home Starts with an Electrical Panel Upgrade Calgary

Most people think of an electrical panel upgrade Calgary project as simply adding more breakers or increasing capacity. In reality, the biggest benefit is protecting your home’s electrical system from overloads, surges, and long-term wear.

A sudden spike in voltage can damage furnaces, refrigerators, garage door openers, and sensitive electronics in seconds. Adding whole-home surge protection during a service upgrade Calgary project keeps that risk under control.

If your panel is outdated or maxed out, it is already under strain. A proper breaker panel replacement Calgary project gives you the opportunity to install surge protection directly at the source—where it is most effective.

Our Process in Calgary, AB

Every home in Calgary is different. That’s why we start with a clear plan and guide you through the upgrade step by step.

Step 1: Load Calculation and System Review

We begin with a detailed load calculation to understand your current and future power needs. This ensures your new panel can handle EV chargers, hot tubs, basement developments, or home offices.

We also inspect your existing panel, grounding, and bonding. If we see signs of overheating or outdated equipment, we recommend the right electrical panel upgrade Calgary solution for your home.

Step 2: Panel and Surge Protection Selection

Next, we size the panel correctly and select a compatible whole-home surge protector. The surge device is installed directly at the panel, where it intercepts voltage spikes before they reach branch circuits.

This step is often included during a full service upgrade Calgary project. It is a small add-on compared to the cost of replacing damaged appliances.

For more details about our panel work, visit our electrical panel upgrade services in Calgary page.

Step 3: Professional Installation and Testing

We coordinate utility disconnects if required and complete the breaker panel replacement Calgary safely and efficiently. Once the new panel and surge protection are installed, we test all circuits and confirm proper grounding.

EV Charger Installation Calgary During Renovations: The Smartest Time to Add Charging

EV Charger Installation Calgary During Renovations: The Smartest Time to Add Charging

Adding EV charger installation Calgary during a renovation is often the lowest-cost and least disruptive time to complete the work. When walls are already open and trades are on site, electrical upgrades become simpler, faster, and cleaner. Crew Electrical Services is licensed and insured, proudly serving homeowners and builders across Calgary, AB.

Why Renovations Are Ideal for EV Charger Installation Calgary

Opening walls for a kitchen, basement, or garage remodel creates direct access for new wiring. This significantly reduces labor hours and patching costs compared to retrofitting after finishes are complete.

Planning ahead also helps prevent panel overload and unsafe extension cord setups that may not meet code requirements. With proper design, your charging station becomes part of the renovation itself — not an afterthought added later.

The Process in Calgary, AB

Every home is different, but our approach remains consistent, organized, and efficient. We coordinate closely with your contractor to keep timelines tight and inspections smooth, including required electric inspections to ensure full compliance.

Step 1: Plan and Assess

We review your renovation plans and assess your electrical capacity, including:

  • Panel size

  • Service amperage

  • Garage layout

If upgrades are needed, we recommend completing them before drywall installation. Many homes benefit from a dedicated circuit or a full electrical panel upgrade to support future electrical demand and pass required electric inspections.

Step 2: Rough-In Installation

We install conduit and wiring while framing is exposed. This stage is the most efficient time for Level 2 charger installation Calgary homeowners prefer.

We also determine optimal charger placement based on:

  • Vehicle parking position

  • Cord reach

  • Clean wall access

The goal is convenient access without clutter while preparing the system for final electric inspections.

Step 3: Final Installation and Inspection

Once the renovation nears completion, we:

  • Mount the charger

  • Finalize electrical connections

  • Complete required electric inspections

Our team handles the necessary EV charger permit process and coordinates approvals to ensure everything meets Calgary’s electrical code requirements.

The result is a seamless system that looks built-in — not bolted on.

Local Permits, Electric Inspections, and Code Requirements

In Calgary, EV charger installations require proper permitting and mandatory electric inspections. We secure the required EV charger permit and schedule all electric inspections to ensure full compliance with local electrical codes.

You can review permitting requirements through the City of Calgary building and electrical safety guidelines. Our team follows current standards to help your installation pass inspection the first time.

What Affects the Cost

The cost of EV charger installation depends on several factors:

  • Existing panel capacity

  • Distance from panel to charger

  • Need for trenching or surface conduit

  • Service or panel upgrades

Renovations often reduce costs because walls and ceilings are already accessible.

Upgrading to a 200-amp service or adding a subpanel increases scope but also future-proofs your home. Hiring a qualified home EV charger electrician Calgary homeowners trust helps prevent costly rework and failed electric inspections down the line.

Pairing EV Charging With Related Electrical Upgrades

Renovation is the perfect opportunity to combine projects.

If your panel is near capacity, consider scheduling an electrical panel upgrade at the same time. Many homeowners bundle EV charging with other residential electrical improvements to avoid multiple service visits and separate electric inspections.

You can also explore EV charger installation services and review service areas if you’re located outside central Calgary.

Electrical Installation Calgary: Powering Your Garage Workshop the Right Way

Electrical installation Calgary garage workshop with dedicated circuits in Calgary AB

Adding a workshop to your garage often starts with tools and layout, but the electrical work is what makes it safe and actually usable. In Calgary, panel capacity, circuit design, and permits all matter. Crew Electrical Services is licensed and insured, and we help you plan the power from day one so the space works the way you work.

Why planning the power comes first

Most homeowners assume a few extra outlets will handle a workshop. In reality, table saws, air compressors, heaters, dust collectors, welders, and even an EV charger can overwhelm an older panel or a single shared circuit. A proper design focuses on capacity, dedicated circuits, and future growth so breakers don’t trip and you don’t outgrow the setup in six months.

Explore our full Residential services or start with an Online Estimate if you’d like a quick, photo-based review.

Our process for Calgary garage workshops

1) Load assessment and panel review

We calculate your total household load and review panel space before any sawdust flies. If there’s room, we add circuits. If you’re near the limit, we’ll map options, including a tidy re-org or a right-sized Electrical Panel Upgrade.

2) Rough-in and layout that match how you work

We plan outlet locations, lighting, and 240-volt connections around your workflow, not just stud bays. That means fewer extension cords and a safer shop. For heavier equipment or compressors, see Power & Equipment Installation.

3) Final installation, labeling, and testing

We set breakers, make terminations, balance loads, and verify grounding and GFCI/AFCI protection where required. Everything gets a clear panel legend so future changes are easy. If something has been tripping or buzzing already, our Troubleshooting & Repairs team will find the root cause first.

Calgary permits and inspections

Garage workshop wiring is permitted work. We handle the application, coordinate inspection, and align with the City of Calgary requirements and current electrical code. You get documentation you can keep for resale or insurance.

What drives the price (and how to control it)

Scope and access matter more than anything else.

  • Panel capacity and whether an upgrade is needed

  • Length and route from panel to garage (finished walls vs. open)

  • Number of dedicated circuits and any 240-volt outlets

  • Lighting layout and dust-collection/heating needs

Good planning avoids rework when you add tools later. If you think an EV charger is in your future, we’ll design with that in mind and can coordinate with EV Charger Installation.

Where we work

We serve Calgary citywide, including Altadore, Lake Bonavista, Springbank Hill, Coventry Hills, and nearby Airdrie and Cochrane.

Why homeowners choose Crew Electrical Services

You get a clean, code-compliant install, realistic timelines, and communication that stays clear from quote to final walkthrough. See how we operate on Why Crew, or reach us on Contact.

FAQ

Do I need a permit for a garage workshop electrical project in Calgary?
Yes. New circuits, subpanels, and most upgrades require a permit and inspection. We handle the paperwork and scheduling.

How many circuits should a garage workshop have?
It depends on your tools. Many shops need multiple dedicated circuits plus at least one 240-volt line. We size it from a load calculation so you don’t overload the system.

Can I just add one new circuit?
For light DIY, maybe. For real woodworking or metalwork, you’ll likely want several dedicated lines or a subpanel. We’ll design the simplest plan that covers what you actually use.

Do I need a panel upgrade?
If your panel is full or near its limit, yes. We assess capacity first and, if needed, recommend a right-sized panel upgrade to future-proof the setup.

Should I hire a renovation electrician for a garage project?
Yes. Workshops combine high loads, code requirements, and safety considerations. A qualified team ensures compliant wiring, proper grounding, and protection that works.
