One surge can cost you
everything.

If you have any expensive electronics — TV, computer, induction stove, EV charger, heat pump, smart appliances — yes. A single lightning strike or utility transient can destroy thousands of dollars of equipment in milliseconds. Whole-home protection clamps surges at the panel before they reach anything.

The Schneider Square D HEPD80 is the better pick if you want the strongest manufacturer-backed equipment warranty — Schneider covers up to $75,000 of damaged equipment if the unit fails to protect. The Eaton CHSPT2ULTRA has a slightly higher surge current rating (108 kA per phase vs 80 kA) and is the choice if raw capacity matters most. Both are Type 2 SPDs and install the same way.

Many policies do, but coverage varies and deductibles often exceed the cost of an install. Some insurers in Ontario now offer a discount for installing a Type 2 SPD — worth asking your agent. Either way, a $749 install is cheaper than replacing a furnace board, TV, and computer at once.

Yes — but for a different reason. The panel-mounted SPD catches large external surges (lightning, grid transients). Plug-strip surge protectors with filtering protect against internal noise from motor-driven appliances and add a layer for the most sensitive electronics. Together is the gold standard.

Under two hours, same-day. The SPD mounts beside your existing panel and lands on a dedicated 30A 2-pole breaker. We power down the panel briefly, install, test, and you are protected before we leave.
