You know who this topic reminds me of?
Good 'Ol Benny!
He posted a detailed message - somewhere, some time ago, which covered the reasoning behind additional "semi-deep" Earthed Electrodes at Lighting Pole Standards' base assemblidges.
It also addressed the reasoning behind why NFPA views it as a Separate Structure (a Concrete Lighting Pole Base) and worthy of a supplimental Electrode.
I just have no idea whatsoever, where this message is located, whaddaheck the topic's name is, even which forum it was posted!
Made a pasted text file copy of the post, and guess what... I don't know where to find it either!
Is it on this machine... maybe it's on one of the drives of the server?... maybe at work... or on the backup machine???... maybe it's on one of the 1,024,056 floppy disk archives?... maybe in a Zip Archive somewhere... maybe on a CD-R, or maybe it's......... did I make a hard copy?...
Shedding a slight tear for the departed Benny.
