Ok heres what I got-

A 200 amp main panel. On that panel I have a 40 amp 240v circuit feeding a dryer outlet. I have a gas dryer and the outlet hasnt been used in quite sometime.

I want to relocate this cable and use it to feed a 100 amp sub panel in my garage. The cable is "Aluminum -B Type SE, #4, Type XHHW, 4 conducter."

The wire will not be run underground nor outside. The total run is about 30ft.

Is this acceptable?

#4 Al is rated for 65amps... so 100amps on it would not be acceptable. If it was fused at the current 40amps it would be a safe wire... but it would not allow 100amps to your subpanel. Overloading the wire results in insulation melt and fire. Be safe.
