A power strip protects a lamp. A panel-mounted surge device protects the furnace board, the heat pump, the range and every circuit in the house. OSB installs whole-house surge protection across Southbridge in a single short visit.
“Whole-house LED retrofit across our warehouse. Our lighting bill dropped and you can finally read labels on the top rack.”
“Garage had one outlet and a light on the house circuit. Now it has a sub-panel and I can actually use my tools.”
“Sparking outlet in the nursery. They came out the same evening, replaced it, and checked every other outlet on that circuit for free.”
It's one of the cheapest protective upgrades available — typically a few hundred dollars installed when there's panel space. Far less than one furnace control board.
No, it layers with them. The panel device knocks down the big hit; point-of-use strips clean up what's left for sensitive electronics.
Nothing stops a direct strike. Surge devices handle the far more common nearby strikes, utility switching and grid transients that quietly kill appliance boards.
Usually under two hours in a Southbridge home, with a short power interruption.
That's the best time to do it, and it's the cheapest moment too.
