I would check with Dopefer to see if they can advise you of the current
capacity of their bussboard but I would expect it to be in excess of 1A so
your requirements shouldn't be a problem.

If the clock module has decent isolation on it's power rail then there
should be little or no `leakage' back up the bussboard so in theory you
shouldn't have a problem. Being on a separate rail is a good idea and would
further reduce and potential problems.

If there is only the one device being connected to the dirty 15V then you
might, in the long run, be better off connecting it directly at the power
supply end of the bussboard or to the power supply itself. This gives a star
connection which is far superior at minimising noise problems.
