SteveSarasota Posted November 30, 2005 Report Share Posted November 30, 2005 Hello, I inspected this condo built in '79 today, and found a 1/0 AL wire connected from the main located outside, to the bus bars at the panel. There was a #12 CU wire connected under the same lug, to the lightning arrestor. Is this ok ? Thanks, Click To Enlarge Quote Link to comment Share on other sites More sharing options...

Bill Kibbel Posted December 1, 2005 Report Share Posted December 1, 2005 I see lightning arrestors installed like this regularly. I always identify it as a concern, but honestly, I've never seen any problems develop. I've read manufacturer's instructions that show it installed this way without any warning about compatibility with aluminum. Quote Link to comment Share on other sites More sharing options...
kurt Posted December 1, 2005 Report Share Posted December 1, 2005 If it's anything other than a lightning arrestor, NO. Since it IS a lightning arrestor, that's how they're all installed. I've never seen any mfg. listing restriction against these things, but then again, I've never looked real hard for one either. Quote Link to comment Share on other sites More sharing options...
SteveSarasota Posted December 1, 2005 Author Report Share Posted December 1, 2005 I just hang up the phone with Delta Lightning Arrestors Customer Service and they said the installation is WRONG!. They Arrestor should be installed/connected to any CU breaker (not double lugged unless is a Square D) and it would protect the complete panel. I love it when I'm right, which is not too often (Just ask my wife). SteveR PS: Any FL inspectors going to the FABI conference this weekend? See you there!

Steve, they're saying a breaker should be installed just for the arrestor to connect to? I've never seen that done, but it makes sense in a way. Brian G.
