".wire 4-square elements are N, E, S, and W, arranged in a box."
 
Hi Bob/KQ2M:  This is Mike VE9AA.with multiple wire 4-squares.
 
Maybe I am simply misinterpreting what you just wrote, but from Northeastern
North America, your prime directions
that you'll be beaming for contests are:
EU (NE)
USA (SW)
AF/PY/some Carib (SE) and
Asia (NW)
 
Thus, you're elements are all in the wrong locations for your stock ComTek
box to work.
 
Your main directions and element placements should be like this (I hope the
formatting holds across the reflector)
 
NW.....NE
.                     .
.                     .
.                     .
.                     .
.                     .   
SW....SE
 
In this diagram, if you were beaming EU from New England, the NE element is
'equivalent' to your director, the NW/SE elements are 'equivalent' to your
driven and the SW element is 'equivalent' to your reflector.
 
That's how I have all my wire 4-squares setup anyways.
 
I have 2 raised radials per.  I don't think it makes a huge difference where
they are, so I am not going to belabour that point, as I know folks will
complain.
 
If I were you, I'd really rethink where I was placing my elements or go with
a different (*modified?) controller, as yours is sure to disappoint.

I want to thank KK9A, NA6O, W4EF, SM2EKM, DCharing (callsign?) and W6RMK,
for 
all of their guidance, comments and links to helpful sites.  Greatly 
appreciated as always!
 
Now for the final question...  let's say that the "positions" of the Gauge
12 
or 14 THHN wire 4-square elements are N, E, S, and W, arranged in a box with
the sides broadside to NE, SE, SW, and NW and all the elements will all have
either 3 or 4 elevated radials.  I will be using the Comtek ACB4 (80)
phasing 
box fed with each element fed with 1/4 wavelengths of RG11 foam coax.  (It's
the same phasing box I have been using for the past 25 years). 
 
Does it matter what directions the radials are pointing for each element?
So 
let's say I am using the NE position on the ACB-4 controller, since I am 
radiating on all 4 elements, does it matter what directions the radials are 
pointing?  Do I want to have the same radial directions with all 4 elements
or 
do I want to spread out the radial directions differently on each element?  
Since NE is by far the most important direction for me (Europe), do I want
to 
have more radials pointing NE or broadside NE or equally spread out so that
the 
radiation and current return is more uniform?   I am not clear on any of
this 
or if it is even important so I would appreciate any guidance that you can 
provide!
 
My understanding is that I want to get the radials at least .05 wavelength 
above ground so at least 13' above ground.  Is that correct?
 
Tnx & 73
