In a 3 gang box is it illegal two have two separate circuits coming in? Example: two light switches on one circuit one light switch on another. The two circuits are separate from each other just sharing the box.
@Zapped,
If you have to ask, you need a licensed electrician.
Insurance companies don't look kindly on DIY modification fires.
@Zapped,
With a name like zapped . . . I wonder if you have already done it?

No. Voltage limitation between devices is covered by Article 404.8 (B) of the NEC. The limitation is 300V, so if you are in a typical dwelling your max volts would be 240V. If your 3-gang box is metal, some have provisions for barriers to provide separation but you should not need that in a dwelling unit.
