We purchased a whole-house protector for our home in Orlando. The company installed it in the main electrical panel in the garage told me the "fuse" (could it be made of epoxy?) was only good for one strike. Most likely the equipment on that circuit would get "zapped" but the rest of the house was protected.
The way he explained it the DUKE energy protector was installed outside of the home (where the meter is) and ONLY protected from lighting coming into the house from the electrical feed from DUKE (like hitting a transformer or coming in on the overhead electrical lines). Those types of strikes are not very common as their equipment is pretty well protected.
He explained that the overwhelming majority of lighting strikes in Florida are related to ground strikes or direct home strikes. The lighting hits a pole, your eave or tree in the backyard, travels down to the ground and radiates out and then "jumps" into your house via an exterior wall outlet, metal pipe, light fixture or switch. Then it goes into your house through that circuit and into the main electrical panel and the surge will then fry all the other lines.
The protector that he installed was the same type Verizon uses on their cell phone towers. He had already installed several.
Not being an electrician or engineer it sounded good to me but I was told by several other companies that the protector from DUKE (with a monthly fee) was basically protecting *their* equipment and really only addressed a small fraction of the usual strikes.
This one is good for one shot---if we take a lightning strike that epoxy block needs to be replaced.
So far so good...
