Quote of the Day
People seldom improve when they have no other model but themselves to copy.
- Oliver Goldsmith, writer. I love to read biographies. I often look to these biographies for inspiration on how to approach my work and home life.
Because I have had to deal with lightning in all sorts of contexts (e.g. military equipment, commercial hardware, consumer products), I have developed an enormous respect for the power of lightning (Figure 1). Because of this respect, I have worked to ensure that my own home has excellent lightning protection, including a sophisticated ground system.
However, even with all my precautions, last weekend lightning struck near my home and caused my garage door to open – letting rain into the garage, and my garage door opener to become unresponsive. Fortunately, I just had to cycle power again on the garage door opener and it started to work. If it were not for that, I might have had to click here and find a quality garage door installation and repair service, to bring the garage door to how it was. Well, I guess, I was lucky, at least for this time. But yes, the place seems to be drenched and needs cleaning!
Unlike me, if you find yourself in such a difficult situation, you could then consider opting for the services of ADP Garage Door Repair of Westminster, MD. (if you happen to live there or nearby!)
This week, a friend sent me these photographs from a fire investigator who was preparing a report on a lightning surge on a home's cable TV wiring. I thought some of you may find these photos interesting. If you are looking for more information on lightning protection, see this post.
In Figure 1, you see where the cable passed through some joists that had fiberglass batt insulation between them. During the lightning strike, the cable became very hot.
In Figure 2, you can see the soot rising above the cable penetration through the joist.
In Figure 3, you can see more soot on the fiberglass batts.
