said by Hahausuck:If we are given directions to do something we follow them to the T. Hence,
we follow R56 to a T as all of our designs are based on R56. When we plan our own sites
we build the site following R56 word for word, no more no less.
What do you do when R56 provides multiple alternatives? Can we choose clamping instead of exothermic bonds? Can we choose bonding/grounding path through building structure instead of copper conductor?
But I really wanted to ask some more relevant and important follow-up questions. Please consider above telecom shelter diagram from R56.
Assume operator wants to bring in some copper T1 and POTS lines into same shelter from different service providers for redundancy.
Assume you have decided to use separate entry panel "per service" because you think it is prohibited to run them through unused conduits in that panel.
What is the R56 guidance on minimum physical separation between separate entry panels?
Do you use one [panel/conduit] per T1? One per service provider if they supply both T1+POTS lines? One for all T1 lines together even if they come from different providers? I reduced some text clutter and drew in 2 panels but you can suggest any number of panels/conduits located anywhere around the shelter.
Where/how do you bond these separate service entry panels/conduits and related surge protectors to the external/internal grounding system?
And one more question, should they have put some more distance between AC and coax entry panel? For a bit more "protection" from lightning surge perhaps.
