Ethernet uses transformer isolation to eliminate earth loops. You may find that this gives you enough protection. I had seen my friends experience.When someone injected electricity power(HVAC) it will burn the HUB and PCs. I didn't check the boards.Maybe it will burn the transformer isolation but must replace the transformer isolation?? THank you Jeckson Ben  |
