A 12 gauge wire would be ideal to use in this situation. This wire is for 20 amp circuit, which is the best to use for electrical appliances at home like your TV, cable box and lamp.

Janemoo and SRF321are correct.
#14 is rated at 15 amps. and #12 is rated at 20amps. The cost difference is negligible but #12 offers a 25% greater protection buffer than #14.

if the panel has 20 amp breakers, I should go with the yellow 12 gauge romex then? dont mix 14 gauge with 20 amp breaker?

No, the breaker amperage should not exceed the insulation value of the wire. That would defeat the reason for having the breaker there in the first place. If you use #14 wire that is rated at a maximum of 15 amps then it must be fed through a 15 amp breaker for proper and safe operation. # 12 = 20 amp, #10 = 30 amp, # 8 = 40 amp...

Yep! That is right make sure you check your amp's on your appliance first?
