Disconnect needed for feeder junction?

[slippery_sid]

I have two outbuildings that I plan to feed with one feeder from a 60A breaker in the main panel at the house, with subpanels in both. The feed will go from the main panel to building #1 and then on to building #2. Option A is to have the feeder enter building #1, go to the subpanel, connect #2's feeder to a breaker in that panel, then back out and on to building #2. Option B is to have the feeder enter building #1, but before the subpanel go to a 3-way junction box that would then "T" to both the subpanel in that building, and out to building #2. The question is, would option B be legal? If the feeder enters the building, goes immediately to a junction box, and right back out, does it need a disconnect before the junction/subpanel? Does the breaker in the main panel at the house count? What if the junction box is outside the building?
Thanks
Alan

If I have misread the situation, if for example you have an electrical contractor on board to perform the installation work, then send me a PM to explain the circumstances.
