In recent years we have seen a huge jump in the demand for load shedding devices in Calgary. This is mainly driven by the City of Calgary Electrical inspections requiring load calculations on new installations of higher demand equipment. These are things like new air conditioning units, hot tubs, EV chargers and eclectic hot water tanks. Older houses usually have 60 – 100 amp services and weren’t designed to handle the type of electrical equipment we are installing today.

If you are planning on adding any of these larger loads to your house, you most likely have heard about load shedding devices. A few years ago these were not that common, but now we are seeing them everywhere

What a Load Shedding Device Actually Is (In Plain English)

A load shedding device is a large switch installed near your panel. It is connected to a selected high demand load like an EV charger or an air conditioner. It is also connected to the incoming service wires to your house with a device called a current transformer th at monitors the current moving through the wires. When the demand gets too high, like if the homeowner is cooking, using the dryer and has a lot lighting loads on, the load shedding device turns off the connected  load until a later time when the demand isn’t so high.

You don’t know this is happening, but your EV charger may end up charging in the middle of the night. It just manages things so you don’t overload your panel.

Why Calgary Inspectors Are Requiring These More Often

When we are installing larger equipment, like the EV charger, air conditioner, hot tub or electric heat, the City of Calgary inspectors are now asking us to complete a load calculation on your home. Its not optional, and it needs to be submitted to close the permit

With most 100 amp services, the load calculation comes back tight. When that happens, the inspector wants to see 1 of 2 things.

1. We can upgrade to a 200 amp service. This usually involves replacing the service conductors, digging up the yard, replacing the meterbase, and replacing the panel. Depending on the complexity, this can run well beyond $7500.00. This isn’t even including the fees from Enmax or Fortis, and thats only if your areas transformer can handle it.
2. We can also install a load shedding device. This is a code compliant way of passing an electrical inspection.

Most people choose the load shedding device because it’s cheaper, quicker, and doesn’t require tearing up the yard or dealing with the utility like Enmax or Fortis.

When You’re Likely Going to Need One

Here’s what we are seeing constantly in Calgary:

• • • EV chargers on 100A service, almost always need a load shedding device
    • A/C installs on older homes most likely need a load shedding device.
    • Hot tubs, almost certain a load shedding device will need to be installed
    • Basement developments with extra heat load depends, but trending upward

If the calculation shows you’re fine, we won’t recommend one. But if you’re close to the limit, it’s better to address it up front than have the inspector fail the job later.

How It Works Day to Day

The device is a box that sits connected to your panel. It is constantly monitoring how much power your home is drawing. If it gets close to the service maximum, it switches off the EV charger or air conditioner. When the household demand drops, usually when its not so busy, the load gets turned back on.

What It Costs in Calgary

Right now, to install a  load shedding device properly with the load calculation, programming, wiring, and permit runs about $1,900- $2,200. Prices vary depending on the house, type of load shedding device and what we’re tying into, but that’s a typical number.

Compare this to a full service upgrade (which can hit $6,000–$8,500+), it’s a great solution.

Why This Matters for Homeowners

The invisible issue is that Calgary homes are getting pushed harder electrically than they were designed for. And the city is noticing.

A load shedding device:

• Keeps your existing electrical service safe
• Gets your new equipment passed on inspection
• Saves you from a major service upgrade
• Lets you run EV chargers, air conditioners and hot tubs together without overloading the panel

We’re installing these constantly now and they always are always a big surprise at the end of a project when the air conditioner or new hot tub fails inspection and load calculation.

Final Thoughts

If you’re thinking about adding an EV charger or anything with a big electrical load, it’s worth getting a load calculation done before you book the install. It’s the easiest way to avoid surprises from the inspector. And if you do need a load shedding device, at least you’ll know ahead of time.

Crew Electrical Services handles the load calculations, permits, and installation across Calgary. If you have questions or want to know whether your home needs one of these devices, feel free to reach out. We are happy to take a look and point you in the right direction.

Power in Calgary is usually steady. It only takes one event to damage a furnace board, a fridge, a TV, or a charger. Whole home surge protection cuts that risk. Think of it as a safety net for everything that plugs in or ties into your electrical system.

Crew Electrical Services installs surge protection that fits your panel, your loads, and your plans. We keep the scope simple, the routing clean, and the labeling clear. You get a solution that works quietly in the background.

What Whole Home Surge Protection Actually Does

A surge is a short spike in voltage. It can come from utility switching, nearby lightning, a motor starting, or a fault. Sensitive boards do not like spikes. A whole home surge protective device sits at the service and diverts excess energy to ground. The result is fewer failures and fewer mysterious “it just died” moments.

This is not the same as a power bar. Strip protectors live at one outlet. A service-level device covers the entire home. It also protects circuits that do not use receptacles, like hard-wired appliances and HVAC equipment.

Where We Install It and How It Looks

Most Calgary homes get surge protection at the main panel. Sometimes we add a device at a subpanel that feeds a garage, a suite, or a shop. Placement depends on your layout and where sensitive gear lives.

What you will see:

• A compact rated device mounted next to the panel

• Short, tidy leads landed on dedicated spaces as required

• Clear labeling on the panel legend so future service is easy

No mess. No guesswork. It should look like it belongs.

What It Protects Day to Day

• Furnaces and air handlers

• AC condensers and heat pumps

• Fridges, freezers, ranges, and dishwashers

• Washers and dryers

• TVs, media gear, and gaming systems

• Office equipment and network gear

• EV chargers and smart home devices

Many of these have control boards. Boards are the first to go during a surge. Prevention is cheaper than board replacement and downtime.

Do You Still Need Point-of-Use Protection

A layered approach is best. Whole home protection handles the heavy lifting. Point-of-use protection adds a second layer for the most sensitive gear. We help you pick where to add strips or in-wall protectors. You do not have to put them everywhere.

How Crew Electrical Services Designs Your Setup

We start with a quick look at your panel and service. Then our team places a device that matches your service rating and available spaces. We keep conductors short for performance, land bonds correctly, and label everything so the next electrician understands the layout.

You will know:

• The device rating and where it sits

• Which panel or subpanel it protects

• How to read the status indicator at a glance

What Happens During Installation

Most installs take a single visit. Power is off for a short window while we land the device safely. We protect floors, route neatly, and seal any exterior penetrations if the meter area is involved. After we restore power, we verify status lights and walk you through what normal looks like.

Common Questions We Hear

Will a surge protector stop every event?
No single device stops everything, but a properly sized, properly installed whole home device handles most daily and seasonal spikes. For very sensitive gear, we add point-of-use protection.

Is this only for lightning?
Lightning is rare. Utility switching, motors starting, and neighborhood work can still cause spikes. Those are the events that quietly shorten the life of boards.

Will this help with flicker?
Flicker often points to load or connection issues, not surges. We can check for loose neutrals, shared circuits, and panel capacity while we are on site.

Do I need a panel upgrade first?
Not always. If your panel has space and the service is in good shape, we can install a device on the existing system. If space or capacity is tight, we will show options.

How will I know it is still working?
Most devices have a visual indicator. We show you how to check it. If you want extra peace of mind, we can include it in a yearly electrical check.

Why Whole Home Surge Protection Is Smart in Calgary

Weather swings, utility work, and modern homes full of electronics create real exposure. A simple device at the service reduces risk across the board. It protects your HVAC during heat waves and cold snaps. It protects your kitchen and laundry gear. It protects chargers and smart devices that are always connected.

This is not a flashy upgrade. It is a quiet one that pays for itself when nothing fails.

Southwest Calgary homes are adding more power-hungry comforts—EV chargers, hot tubs, air conditioning, home gyms, finished basements. If your panel is cramped or you’re juggling breakers, a 200 amp electrical panel upgrade in Southwest Calgary gives you the headroom to live the way you want without workarounds.

Crew Electrical Services plans and installs upgrades that feel seamless: clean layouts, clear labels, correct sizing, and inspections passed the first time. Our focus is simple—safe capacity today, room for tomorrow.

Why Upgrade Now

The way we use electricity has changed fast. One EV becomes two. Temporary offices become permanent. That backyard project turns into a hot tub and patio heaters. Instead of squeezing another tandem breaker into an already busy panel, upgrading to 200 amps creates breathing room so new circuits land where they belong—on dedicated, properly sized breakers.

Crew Electrical Services starts with how you live, not just what fits on paper. We size your service for real days in your home, winter to summer.

What a 200 Amp Upgrade Includes

Every house is different, but most Southwest Calgary upgrades include:

• A new main panel with ample spaces and clear, durable labels

• Service capacity increased to 200 amps (with meter base and mast changes where required)

• Grounding and bonding brought to current standards

• Optional whole-home surge protection for modern electronics and HVAC boards

You’ll see a tidy, intentional installation—not a patchwork of add-ons.

Signs Your Panel Is at Its Limit

You don’t have to wait for constant trips. Common red flags:

• Few or no open breaker spaces; tandem breakers used as band-aids

• Warm breakers or buzzing under normal load

• No obvious place to land circuits for EV charging, hot tubs, AC, or a basement suite

• Lights dimming when large loads start

Crew Electrical Services performs a proper load calculation and gives you a straight answer about capacity and options.

How a 200 Amp Service Future-Proofs Your Home

A 200 amp service is the modern baseline for Southwest Calgary:

• EV-Ready: Add one—or two—chargers without starving the rest of the home

• Comfort Add-Ons: Hot tubs and air conditioning live on their own dedicated circuits

• Renovation-Friendly: Space and amperage reserved for new rooms, suites, or workshops

• Resale Confidence: A clean, labelled 200A service is a signal of care and readiness

It’s not about chasing a bigger number—it’s about buying options.

Our Process (Clear and Low-Stress)

Walkthrough and Planning
We review your goals (EVs, hot tub, AC, renovation), inspect the existing panel and service entry, and note any constraints in utility rooms or finished spaces.

Load Calculation and Design
You get a calculated service size recommendation and a panel layout that reserves spaces for the big loads you have—and the ones you’re likely to add.

Permits and Utility Coordination
We handle permits and book the utility shutdown/reconnect. You’ll have a clear schedule and know exactly when power will be off.

Upgrade Day
Our electricians replace the panel, set grounding and bonding correctly, land conductors, and label circuits neatly. If the meter base or mast must change, we handle that too and seal everything properly.

Inspection and Walkthrough
We meet the inspector, close the permit, and give you a quick tour so you know what’s where. No guessing, no mystery breakers.

Planning for EV Chargers, Hot Tubs, and AC

A panel upgrade is the moment to think ahead. Crew Electrical Services can pre-label reserved spaces, install conduit stubs to the garage or exterior wall, and size the service with those future circuits in mind. When the time comes, the equipment lands cleanly on the capacity you already have.

Grounding, Bonding, and Surge Protection (The Quiet Essentials)

Fast-acting protection makes failures rare and recoverable. We bring grounding and bonding up to current code and recommend whole-home surge protection so HVAC boards, appliances, and smart gear aren’t sacrificed during a storm or utility event. These details aren’t flashy—but you’ll be glad they’re there.

Working in Older Homes and Finished Spaces

Southwest Calgary has a mix of eras and layouts. Tight utility rooms? Finished ceilings near the panel? We plan routes and mounting that maintain clearances, keep service points accessible, and avoid unnecessary tear-outs. The finished result looks like it belongs.

Common Pitfalls We Avoid

• Overstuffed panels with tandem breakers standing in for real capacity

• Old grounding/bonding carried forward “as is”

• Last-minute utility coordination that drags timelines

• New EV, hot tub, or AC circuits added without a load plan

• Sloppy labeling that makes future service slow and frustrating

Crew Electrical Services builds upgrades that are easy to live with and easy to service.
