Hello Sirs,
I have a doubt regarding the connection between this two grounding electrodes, i uderstand that this is to comply the 250.4(A)(1), specifically atmosferic discharges, however this is my doubt:
Why is not required a jumper conductor to get equalization state between the two separate grounding electrode systems? a lighting transient can rise through the grounding electrode conductor and create a current loop between both electrodes through the feeders. EMC
I mean a transient (8/20s) could be induced to this feeders, and eventually bring out hazard in wherever branch circuit over...
If somebody knows the answer to my doubt i will appreciate the help.
Regards,
