A client of mine said that this power supply that feeds his internet equipment literally exploded today while a storm was going on. He claims that this has happened 15 or so times, no matter where he has the internet equipment plugged in. I found no electrical issues whatsoever, except a scorched plug from this box burning. The internet company says it’s the power companies issue…. It seems clear to me the problem is with the internet coming into the house, but I’m just a dumb electrician. Also, apparently the isp disconnected all equipment bonding jumpers at the service equipment bar, and told my client that they added grounding at the pedestal in his front yard to remedy stray voltage they were getting on their cable. Anyone seen this before, and what could my next steps be? should I just tell him to call isp again for the 10th time?
