Power tracks wiring

Question

Hi. 
 
 If i have a 63A power track, and the power consumption on it is less than 63A, can i use a smaller breaker when circuiting?

Assuming I have understood the question, and that can be the first step .. 
 It sounds like you are using a track with a maximum rating of 63A to supply a lesser load - say perhaps 20 or 30A ?, and you propose to supply the track from a breaker more closely matched to the load ? 
 Yes, you certainly can, it may be a bit of a waste to use track with heavier conductors than the absolute minimum you would need - rather like using a thicker extension lead to supply a table lamp, but there is certainly no reg against it. 
 Arguably makes future upgrade easier if ever the load increases, and in the meantime means it all runs cooler and so is likely to last longer. 
 Mike.
