Depends on what you mean as to how you intend.

Physically, two 14ga wires paralleled would be adequate, yes, but if
you're speaking of household wiring, NEC forbids multiple connections on
a breaker terminal so that expedient isn't allowed.


Are you sure? I'm quite sure there is more than one wire per breaker
in many panels - or would there be one wire on the breaker, tied to 2
or more with wire-nuts? Easy way around that would be heavy wire to a
junction box, where two light wires were connected. However, having 2
LIVE wires connected to one device is, as far as I know, against code.
