Excellent investment against lightning damageUtility company power is usually steady and safe, but stuff happens. There's 50 miles of overhead line from the generating plant to my house. When lightning strikes, the utility company absorbs most of the surge, but some gets to my house. Car accidents and other line damage can also put excess voltage on the line.
I've lost several appliances over the years to lightning and line-surge events. Home insurance can cover this, but unless you lose several major appliances the loss is usually less than your deductable.
So I believe in surge protection.
Ideally this starts with good Grounding at the service entrance. A surge protector at the meter is a good next step. Then a protector in the breaker-box, finally a surge-strip at critical appliances.
This surge protector goes in your breaker box. It must match the brand of box you have. It must be installed by a qualified electrician, because an accident inside a breaker box can cause serious injury and damage. You must have a 2-unit free space, very preferably near the main breaker/lugs.
While this protector (plus installation) is not cheap, it may be much cheaper than the damage caused by lightning or other electrical event.
It installed easily. Obviously I can't review it for surge-performance, but I know it has been evaluated by Schneider Electric and tested by UL to appropriate specifications.
The warranty covers surge-related damage but is secondary to your homeowner's insurance; Schneider pays your deductable after you submit a claim to your insurance.
