[R-390] Inrush Current Limiters

If it were me, I would balance the slightly more convenient installation 
of a component that fails open leaving the chassis hot, as opposed to 
the slightly more inconvenient option of not being dead. Me, I say screw 
the 'I Love Pain. It Means I am still Alive" school of thought. Never 
put anything in the neutral line that can possibly fail open. It is like 
playing Aggie Roulette. That's like Russian Roulette, except you use 
your trusty Colt 1911A1 Automatic. (if you don't know what an Aggie is, 
see http://halife.com/files/aggie.html)

The reason I ask is where I want to install this one is on the neutral side (it's slightly more convenient); however, if the ICL fails in an open mode, then it could act like a blown fuse and if it's on the neutral side, then the radio would be dead, but there would still be power up to the ICL (same reason it's not a good idea to install a fuse on the neutral side).  If it fails in a closed mode, then it really wouldn't matter.  I'm just trying to decide if I really want to install it on the less convenient hot side or just go with the neutral leg.  Any comments?
