Lightning and Ethernet

Found an article I read a while ago and thought I would share it. Based on this I’ve been using medical grade Ethernet isolators (IEC 60601 compliant) for surge protection inside, not for better sound.

Important to note that the article is discussing developing research so I wouldn’t say anything is fully settled yet.

Part of why I’m paranoid is that I have almost all of my expensive gear in the house hard-wired to copper based Ethernet:

• TV
• HT Receiver
• Roon end point
• 2 PCs
• BD Player

So if a surge travelled down the Ethernet into my gear it would do a lot of damage, even if that damage was relatively lite, like taking out the Ethernet ports.
