Hi everyone,
This is my first post here, so I appreciate any help or guidance you can offer.
I’m working on a 1200A bus gutter system under NEC standards, and I’m looking for some clarification regarding lug spacing requirements, if any are defined.
The setup includes:
The voltage is 600V, and the system includes 3 phases and a neutral.
Does NEC specify a minimum spacing between lugs in a bus gutter, or is this more of a practical design consideration (e.g., for bending radius, heat dissipation, or accessibility)?
Any references to specific clauses or tables in the standard would be especially appreciated.
Thanks in advance!

The setup includes:
- A main lug connection with 3 x 600 MCM aluminum conductors per phase
- 5 branch lugs, each with a single 250 MCM aluminum conductor
The voltage is 600V, and the system includes 3 phases and a neutral.
