I am fixing to install a new breaker and run a wire to my deep freeze and one flouresent light. It is a 20 amp breaker and was hoping to use 14-2 wire since i have a whole role laying around. Will this guage be sufficient, Or should I get 12-2?

You can use 12/2 with a 20 amp (or 15 amp) breaker.
You can use 14/2 with a 15 amp breaker.
You can use 10/2 with a 30 amp breaker.
Use 12/2 in this instance (at least that is what I would do, although I'm not an electrician). 14/2 may be adequate, but one of the pros in here can tell you.
I have no clue what the code is. LOL

Old Guy, you hit right on the money. Good Code work.

lostintexas, you may use the 14/2 Romex only if you protect it with a 15 amp breaker or fuse. 20 amp breaker or fuse is too high for the ampacity of the 14 awg wire.

Like Old Guy said, I would use 12/2 with a 15 or 20 amp breaker. This freezer is an automatically ran 24/7 appliance that cycles on and off. It uses enough electricity a year to pay the extra cost of the larger 12/2 cable commonly in that first year considering the reduced resistance of that larger wire. Any dollar savings after that is gravy!

Good Luck
