A-C Mains (electrical) practice has always (at least since the 30's) been 
generally opposite to standard electronics practice, except for red, which is 
hot in both cultures.  Look for example in any Command Set (the generic 
term, not the AAF's function term) chassis and you will see black (or bare) for 
virtually all ground leads of any sort and black not usually used for 
anything else.  Generally the same in most US built sets.  It's just something 
that "you know" and don't conciously even think about.  So using white for 
Common would be contrary to common practice.
