This may be slightly different in the US, but in Canada you 
cannot obtain CSA electrical approval unless there is only 
one line fuse, on the hot wire. Fusing the neutral is 
dangerous, if that fuse blows then all of the ac circuitry 
floats up to the 120 VAC level with respect to ground. I 
have had to remove the neutral fuse from many pieces of 
equipment in order for them to pass approval and be sold in 
Canada.

Take care,
Doug
