I have a project where existing 3-parallel conductor runs connect the portable generator disconnect to the generator switchgear. The generator switchboard is 50ft vertical in the 4th floor. As per NEC table 300.19(A) conductor support is required at 40ft vertical raceway for 600kcmil. The existing 3-parallel runs goes to a junction box around at around 40FT and has conductor support bushing.
My questing is: I'm planning on adding one more parallel run to existing three. There is no space at weight relief junction box for another conduit. Is it possible to add separate junction box and provide bushing for new set of conductors only? Or all of them has to be together?
Thanks in advance.
