Problem is my deductible is probably ~2K so insurance isn't going to help. In theory (and I might be saying something you know so apologies if so..) the Protector should either "clamp down" or get destroyed. Either way not allowing the spike to go through. Thats the theory.. can't say I know it worked for sure (and I am not an electrician so...)I am not sure how to protect from lightning coming in through the ground or bond. I have seen many spas damaged by it, though. It's the only thing that takes out everything electronic. I have seen it covered by insurance almost every time, and there are usually electronics in the house damaged as well.
