We were doing a seismic upgrade on the roof of one of our buildings 2 summers ago in late June (SF bay area) when that one freak early summer storm rolled in and it turned into a good thunder and lightning storm. The building housed a server farm for one of the cell providers (huge power loads) and we had done a pretty thorough job of covering the roof in preparation. However as the weather forecast started to get really nasty I called a bunch of guys in to make sure we were going to be good. We had just got there (9pm) and I was climbing the ladder and all of the sudden it appeared the transformer blew up, I mean BLEW up, I was at the top of the ladder maybe 100 feet away and my first thought was oh S**T water got in the switch gear and we just blew the place up $$$$$$$. The two onsite back up generators kicked on and the frenzy started. Once the sun came up we saw that lightning had hit the bus ducting and blew an 18" hole right threw it and took the t former with it. Lightning aint no joke!
