Is this correct,practical,or not to code. I have three pcs of equip to move to another spot in shop at present fed from busway (three seperate drops) ITE, bull dog type , new spot is only about a 15 ft run away from GE spectra busway, no 30 amp buss plugs in house 1- 60 amp in house. ea piece equip 240 1 ph 15 amp, could I use 60 plug,fused at 60 # 6 thhn run to centralized box tap 3 runs to 3-30 amp fused disconnects ea fused at 20 -12 thhn that feed recepts for ea equip . 30 amp buss plugs are about $400.-$500. ea plus not always on shelf. Other alternative 80 ft away is panel then theres 3-2 pole breakers conduit run..... Just want to do whats right

What you are describing sound to me like it fits within the tap rules. I think your answer lies in 240.21(B). It will depend on the length of #12 conductors. Also, you need to have the #12s in some sort of raceway, or have them protected from physical damage in some approved way.

By the way, why not use #14 wire, 15 amp fuses, and 15 amp rated receptacles? Does the equipment's operating & maintenance instructions allow for use of 20 amp receptacles?

Everything will be in conduit and for some reason they had 20 amp cord ends spec plate states 15 amp ? I was going to fuse the disconnects accordingly and Im sure keep length less than 10 ft to ea 30 amp disco, hmmm does this 10 ft include length after discos to recepts ?

. . . hmmm does this 10 ft include length after discos to recepts ?

No. Once you reach an overcurrent device (i.e., the fused disconnect), you are no longer dealing with a "tap." At that point, you have a branch circuit, and it is not covered by the restrictions in the tap rules.
