[Amps] 240V Outlet

Here is a question about the NEC code.  Is it legal to have more than 
one branch circuit in a single switch box?  One time I was installing a 
new garbage disposal.  The switch for the disposal was in a box 
containing 3 switch.  The other two were for lights.  As it turned out 
the disposal was on a separate circuit from the lights.  I found out 
when I hooked up the wires to the new disposal.  I connected the hot 
wire and when I started connecting the neutral, the disposal started. 
Fortunately I had not touched any bare wires.

I guess the moral in this is to check all the wiring in a box before 
doing any work.
