outdoor wire

I am adding an outdoor box and connecting it to another outdoor box. I ran out of 12-2g, but found some 14-3-g. Can I/should I splice the two in order to finish the run of about 15 feet?
thanks

These are outdoor boxes, is the wiring being run outdoors too?

Sounds like you're working with cable. What kind of cable are you using? Are you running it in conduit? Is it buried?

Type NM is only rated for use inside closed spaces in the interior. It is not rated for use outdoors, not rated for direct burial, and not rated for installation in conduit.

You need to use a different wiring method.

Reading a copy of Wiring Simplified would probably answer a lot of questions for you.
