[QUOTE="BobTheBuilder, post: 1024334, member: 14105"] Thanks, Family_Dog. I would agree with you, but there is a practical limitation that I am not always at home. I agree that induced EMF is the most likely cause. It would also explain why the RS232 connections all got fried and took out my batteries and inverters. Interestingly the earth leakage also tripped indicating some sort of EMF effect coupled with probably the local potential of the earth being raised significantly. From what I can tell (thanks to the UPS) none of the electrically connected equipment died (for example the power amp) and it was only equipment that was connected either via HDMI, Ethernet, or RS232 that got taken out. Perhaps there is some way of disconnecting all communications interfaces during a storm, remotely, using WiFi for that device, but I know of no such thing. [/QUOTE]
