[TowerTalk] Station Ground

[Alan NV8A (ex. AB2OS)]

Maybe I have misunderstood what I have read about the National Electric 
Code, but your suggestion about having a ground bus connected to the 
*neutral* sounds like a violation because it could establish a 
connection between the neutral and the ground (if you connect to this 
"neutral bus" a device that has a ground connection via the green wire 
in the power cord) other than at the service entrance (which typically 
means at or close to the meter).

ever-growing pot of cybersoup:
