I've made several of the zero clearance inserts (for different blades) and always made the slot with the blade I intend to use it with. Of course, you need to match the inserts to the blades (I just tie wrap them together.

My dewalt d27105 saw keeps blowing a fuse
These saws have a rather large amount of draw on a 15 amp breaker... they should be able to operate on a 15 amp breaker, however nothing else can share that breaker.... and if it is an outside plug (GFI) it will be even more likely to trip. If possible, use a 20 amp breaker...they can be found in the garage where central vacuum plugs in. If this isn't an option then ensure nothing else is on a normal 15 amp breaker, use a heavy gauge extension cord, and the shorter the cord the better.

Dewalt flip saw keeps blowing fuse
common problem with this saw is the brushes when worn down to about half inch, won't go into the brush holder any further and starts to arc against the commutator. eventually the heating will burn out the commutator. a replacement armature will cost you $75 plus shipping.
