Re: distance for tap box
I'm not sure I understand your question. Is there a specific code article that you think may be a problem? And why a 150 amp disconnect feeding 3-60 amp disconnects? Why not simply tap the 250 amp feeder and feed all of your disconnects?

Re: distance for tap box
in 240.21(B) there is no mention about how far the ocpd is from the tap or the length of the feeder used for the supply of the tap conductors.
