Whole of House Surge Protection
Over the last couple or three years, I have had a WI FI card and one , possibly two PCs rendered inoperable, through lightning strikes . Ordinary plug-in surge protects are not enough without strong protection between the house and the mains grid. This device carries a very substantial warranty, and has a current protection rating of 80,000 amps. While the warranty might or might not provide cover outside of the US, this doesn't worry me - as I think that the makers of this device have a lot of confidence in their product to offer 5 year / $75,000 cover. Bear in mind that in this country (Australia), as probably in most places, an Electrician is required to fit the device, although clear instructions and basic wiring diagrams for both 240V single phase and 440V three phase installation are provided.
My dwelling is a steel framed transportable, with steel footings into the ground; this acts a bit like a Faraday cage, when lightning strikes the house ... the scorch marks and little areas of molten galvanizing on the iron roof cladding are clear evidence of a direct strike! The "Faraday cage" house frame is safe protection - but using any water plumbing fittings or land line telephones should be seriously avoided during a storm.
