However, someone has pointed out that a lightning strike will go through a surge protector.
So I have the facts that: * Surge protectors do not protect against lightning. * RJ-11/RJ-45/Cable do not 'surge' without lightning (?) so it seems that the RJ-45 etc surge protectors are a scam. Does it have to do with how close the lightning is? How does lightning hit an underground cable line? I know phone lines carry power [or they do back home, I assume they do here too]. So I can see how they could surge. But I'm assuming cable doesn't carry power in anyway, and I know RJ-45 doesn't usually carry power.
