I was thinking of a tower with its own transformer on the pole. I know at the breaker panel at the H-frame there is typically a neutral bar and a ground bar, and I’ve seen several volts between them, also bad things when some rural electrician thinks they are interchangeable (many farmhouses don’t have grounded outlets or metal conduit, and some electricians figure neutral is better than nothing).

Yes, they are tied together somewhere, probably the transformer. But you should not use the neutral as a ground or tie it to your ground anywhere.

I have a grounding question for the cabinet at the base of the tower. My electrician wired in the incoming power to the cabinet but he did not bond the cabinet ground/neutral to the actual tower itself. Tower has its own separate ground rods and cabinet ground actually is back where the meter base is, (over 150 feet away) Should I bond the tower and the cabinet together? I already have electrical conduit running out of the cabinet and then attaches to the tower itself so there is metal to metal contact just wondering if I should have something better....

Great question Gino. I hope we get some good input. My opinion is that you have to be completed isolated or extremely properly grounded. Both can be complicated, but the second way being the most complicated Paul From: Af [mailto:[email protected]] On Behalf Of Gino Villarini via Af Sent: Sunday, September 28, 2014 7:31 AM To: [email protected] Subject: [AFMUG] Gear in Tower - Grounded or Isolated? I remember the good old days that most of our network was based on Canopy Classic: The radios were isolated form the tower, minor lightning issues.. Nowadays its has turned into a big issue for us, radios and MW getting zapped! Were do I start? Should I go back to the Isolation model and have all gear in tower isolated from the tower in any way possible? Gino A.
