Hi Richard,

No BX (Type AC armored cable is what BX really is) is not allowed to terminate without being terminated into a proper box in a proper fitting.

From the 2005 NEC, which is applicable all across Florida. (bold and underlining are mine)
- 320.40 Boxes and Fittings.
- - At all points where the armor of AC cable terminates, a fitting shall be provided to protect wires from abrasion, unless the design of the outlet boxes or fittings is such as to afford equivalent protection, and, in addition, an insulating bushing or its equivalent protection shall be provided between the conductors and the armor. The connector or clamp by which the Type AC cable is fastened to boxes or cabinets shall be of such design that the insulating bushing or its equivalent will be visible for inspection. Where change is made from Type AC cable to other cable or raceway wiring methods, a box, fitting, or conduit body shall be installed at junction points as required in 300.15.

No, one is not allowed to just terminate Type AC armored cable inside a wall and allow the conductor to hang out of the Type AC cable exposed within the wall.
