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 North Grafton in a single short visit.
“Sold our house and the buyer's inspector flagged eight electrical items. OSB fixed all of them in one visit and wrote it up so we could close on time.”
“Six recessed lights in the kitchen and a dimmer that actually works. The ceiling patch was so small I didn't need a painter.”
“Garage had one outlet and a light on the house circuit. Now it has a sub-panel and I can actually use my tools.”
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 North Grafton home, with a short power interruption.
That's the best time to do it, and it's the cheapest moment too.
