clothes dryer circuit??

In America, we do not have 5 wire clothes dryer circuits. New construction has 4 wires. Red=120V Black=120V White=Neutral and Green=Ground. Nuetral and Ground should be isolated from each other. In other words, they should not be connected to a common ground. The green wire should be connected to the frame of the dryer. The red, black, and white will connect to a wiring block in the dryer. Hopefully the home already has a 4 wire receptacle. If your receptactle only has 3 wires it is probably way beyond what you could safely do with your lack of experience. Call a friend who is an electrician or spend the bucks.

If your home is set up with a 3 wire receptacle, and you just bought a new dryer that came with a 4 wire pigtail it would be a whole lot safer, easier and cheaper to go buy a 3 wire pigtail to match your homes wiring.

Now, because you mentioned 2 pole breaker, if you are totally running a new circuit from the box to the dryer just by 4 wire. Dryers require a 30 Amp circuit. Most contractors run 8 gauge wire. The Red wire goes to on pole and the black to the other pole on the breaker. White goes to the neutral bar and green or bare goes to the ground bar.

I know I probably don't need to say this but just in case....be sure the power is OFF at the main if you are working in the box. Remember that power will still be where the wire connects to the main breaker so just because the circuits are dead doesn't mean the whole box is dead. Also remember while you are sliding the blades of the plug into the receptacle for the dryer that once those blades touch metal they are energized. The blades of the plugs are long and you could easily make contact with power while plugging in the cord. Be safe and keep the circuit off until you have plugged the dryer totally in.

a five wire? do you mean a four wire? 2 hots neutral and ground.
