wire size for L14-20?

I am putting in a NEMA L14-20 outlet to power an electric smoker oven. The oven is 220v, 60 cycle, 3050 watts. I am using a 20a double pole breaker. What size wiring do I need for this and also how do I hook it up to the breaker/panel? The electric store people sold me some 6-3 but it seems too big.

thanks for any advice

I think you need to get some good electrical DIY books before you venture into you main panel. This is not any place to mess around without some prior knowledge.

Did you tell the store folks what it was you needed to wire? Did you tell them the wattage and voltage? If you did and they sold you 6/3 wire DO NOT ever go back there for any reason. They have no clue!
Actually it is not their job to size wire and circuits for you but they should at least have the fortitude to let you know something is amiss. #6 will not even fit on most 20 amp breakers.

Also, is this appliance a 220 volt or 110/220 volt?
An L14-20 is a 4 wire twistlock configuration. If your smoker is a straight 220 appliance you do not need a 14-20R, you need a 6-20R and you do not need a twistlock unless you wanted one. Also in this case you do not need 3-wire. 12/2 is what you need.

If it is in fact a 110/220 volt you need a 14-20R and 12/3 wire.
