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 Sandwich in a single short visit.
“Our panel was original to the house and completely full. OSB upgraded us to 200 amp, pulled the permit, met the inspector, and left the basement cleaner than they found it.”
“Garage had one outlet and a light on the house circuit. Now it has a sub-panel and I can actually use my tools.”
“Two-prong outlets all through a 1920s house. They grounded what could be grounded and GFCI-protected the rest, then labelled everything.”
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 Sandwich home, with a short power interruption.
That's the best time to do it, and it's the cheapest moment too.
