Whole-Home Surge Protection

Whole-Home Protection

residential surge protection

One surge can take out everything you've plugged in

Most people picture a lightning strike. In reality, the majority of surges come from far less dramatic places — utility switching on the street, a transformer fault, a well pump or air conditioner kicking on, or a neighbour’s equipment cycling. They’re small, they’re frequent, and they quietly shorten the life of everything electronic in the house.

What’s at risk has changed too. A home today runs on circuit boards: furnace and heat pump controls, EV charger, inverter appliances, LED drivers, security systems, TVs and computers. Replacing a furnace control board alone can cost more than the protection would have.

We install CSA-certified surge protective devices at the panel, add point-of-use protection where it matters, and verify the grounding and bonding the whole system depends on. Work is ESA-licensed, notified and inspected.

What we install

Layered protection, not a single power bar.

Surge protection works best in stages, one device at the panel to knock down the big hits, and smaller ones close to the equipment you care about most.

Main defence

Type 2 Panel-Mounted SPD

The workhorse. Mounted at or inside your electrical panel on a dedicated breaker, it diverts surge energy coming in from the utility before it reaches your branch circuits.

Service entrance

Type 1 Service-Entrance Devices

Installed ahead of the main breaker, on the line side. Used where the service is exposed, on rural feeds, or where an extra stage of protection makes sense before the panel.

Sensitive equipment

Point-of-Use Protection

A panel device can’t stop everything. Type 3 protection at the outlet handles what gets through and blocks surges generated inside the home, close to your home office, media wall or appliances.

Big-ticket items

Heat Pumps, EV Chargers & Generators

The equipment with the highest replacement cost is often the most sensitive. We protect these loads specifically rather than relying on the main device alone.

Incoming lines

Coax, Data & Communication Lines

Power isn’t the only way a surge gets in. Cable, internet and phone lines carry them too, and a surge that enters through the modem finds its way through the network like any other.

Foundation

Grounding & Bonding Verification

An SPD sends surge energy to ground. If the grounding electrode, bonding or neutral connections aren’t sound, the device can’t do its job. We check this before we install anything.

Done properly

Why surge protection fails, and how we avoid it

Most devices we’re called to replace didn’t fail — they were installed in a way that never let them work properly in the first place.

CSA-certified devices listed for the application, not hardware-store power bars
Sized on surge current capacity and let-through voltage, not just price
Mounted on a dedicated breaker to the manufacturer's specification
Leads kept short and straight — every extra length raises let-through voltage
Grounding electrode and bonding verified before the device goes in
Point-of-use protection added where the panel device alone isn't enough
Status indicator explained so you know if the device has done its job and needs replacing
ESA notification handled as part of the work, with the certificate on file

Surge Protection

Protect what's already in your house.

A single device at the panel costs a fraction of what one surge event can take out. Book an assessment and we’ll tell you what your home actually needs.

FAQ

Common Questions

My breaker keeps tripping. Can I just keep resetting it?

A breaker trips because something on that circuit is drawing more current than it should, or because there is a fault. Resetting it repeatedly does not address the cause and is not safe as a long-term habit — have the circuit looked at.

How long does troubleshooting take?

It depends entirely on the fault. Some are found in minutes; an intermittent problem that only appears in certain conditions takes longer. We will tell you what we are seeing as we go.

Is troubleshooting available outside business hours?

Yes. Our professional team is available 24 hours a day, 7 days a week for emergencies.

Can you work on wiring installed by someone else?

Yes. A large share of our repair work involves correcting or completing wiring done previously by others.

Which areas do you serve?

We serve Burlington and the surrounding areas of southwestern Ontario, including Oakville, Hamilton, Hamilton Mountain, Stoney Creek, Grimsby, Flamborough, Dundas, Ancaster, Campbellville, Milton, Waterdown, West Lincoln and Haldimand. Not sure whether you are in range? Send us a note and we will tell you.

Do you offer emergency service?

Yes. Our professional team is available 24 hours a day, 7 days a week. Keep 905-634-5577 handy, or contact us right away.

Are you licensed and insured?

Yes. Brant Electric Limited is a licensed electrical contractor and a member of the Electrical Safety Authority. Where a job requires ESA notification, we handle that as part of the work.
