i'm an electrician in the surge capital of the world, Orlando ( did lightning just hit that house?), Florida. the last three days were spent devouring old towertalk threads on grounding, super informative! well, surge protectors are pretty useless without a good ground and armed with towertalk knowledge i was ready to give my customer's the best ground their money could buy.
then, a really sharp engineer at Intermatic dropped this little bombshell. if your ground is a lot better than the utility's ground at the transformer then all the neighborhood's surges are coming for a visit. and you might think they're just coming to your ground, but, as they travel the common they induce surges in the two hots. So, you may have dodged the big surge, and bought yourself a whole lot of little ones.
is this significant? do i need to put a big horkin MOV on the neutral to the meter that'll add a couple dozen ohms and keep the neighborhood's surges out? is there such a thing?
all kidding aside, i'm guaranteeing all appliances and electronics to $10,000.00 or the homeowner's deductable (installing Intermatic IG1300-4T-2C). please help.

Why won't the Intermatic unit do the job? By the instruction manual it appears to offer protection for both the ground and neutral?
