MV Cable Termination Bonding

[luckylerado]

I have not done much MV termination. I am looking for input from the MV folks here on the proper way to bond the MV terminations. Photo below. I generally see these bonded back to the GB in the gear individually. This installer has bonded each phase together and then back to a bonding lug on the raceway which is then bonded back to the GB. Is this compliant? Not finding what I am looking for in NEC. MFG instructions show individual EGC for each termination but only when ran through a CT. Thanks for you input and code references would be helpful if this is in violation.

What's GB here? Ground Bus?

Yes Ground Bus

Is the equipment shown connected to the EGC? I see a green wire disappearing off into the void...... If that bonds to that equipment, then everything looks fine to me (disclaimer, I don't do much MV). Does seem like you may have some listing violations with the conductor combinations put under the split bolt and the lugs. Only other potential thing I can think of which I am not sure about, is grounding of the cable Shields. You obviously want to do that and you can see it's done on this end, but if I remember correctly there is some design that goes into bonding at one end or both ends which may affect management of shield currents. Perhaps someone with a little more knowledge in the area can comment more on that.
