thanks for the post rmiell.
I did leave out that each of the outputs to the HVAC units were individually fused, so in my opinion the 400 amp breaker was a little overkill/useless. Here is a quick layout of our system:
1. Generator (when the contactor is opened all power is killed to the whole system)
2. ABT (transfer switch incase primary generator fails will switch to back up)
3. NEW junction box (splits to 6 outputs to HVACS and feedthru for rest of system)
4. Distribution box (splits the 3 phase into 3 seperata phases to supply power to 3 different communications tents)
after the last distro box it goes to some 15, 20, & 30 amp outlet boxes. Every one of the outlets have their own individual breaker, so I think it would just be overkill to have the 400 amp breaker in the NEW junction box, unless it killed all power, and just not to the HVACS.
Once again I appreciate your reply, and have a great weekend.
