[RE-wrenches] Lightning protection system

[Drake Chamberlin]

I didn't get a reply to the question about connecting the GEC to the 
lightning protection system on the 8 story building.  Although this 
may seem like an intrinsically dangerous idea, a lightning protection 
system is required to be bonded to the building grounding electrode system.

"250.106 Lightning Protection Systems.
The lightning protection system ground terminals shall be bonded to 
the building or structure grounding electrode system."

It would therefore seem that the suplemental ground could connect to 
that system as well, and in fact use the existing conductor.  Any 
input would be welcome.

Thanks,

Drake
