Which is the blue wire in the three pin plug?
This is connected to a fuse on the live pin. The electric current uses the live wire as its route in. The NEUTRAL wire is BLUE. This is the route the electric current takes when it exits an appliance; it is for this reason the neutral wire has a voltage close to zero.
Where does the blue wire go in a plug?
In a plug, the blue neutral wire goes to the left, the brown live wire to the right and the green and yellow striped earth wire to the top. The fuse fits next to the live wire.

What does the fuse do in a 3-pin plug?
The fuse breaks the circuit if a fault in an appliance causes too much current to flow. This protects the wiring and the appliance if something goes wrong. The fuse contains a piece of wire that melts easily. If the current going through the fuse is too great, the wire heats up until it melts and breaks the circuit.

Why are earth pins used for 3 pin plugs?

What kind of flex do you need for a blue plug?
Connect it to your blue plug with 3 core 2.5mm flex. Ideally some orange artic flex. Ideally you would use a moulded rubber trailing socket – have a google and I am sure you will find one. Moulded plastic can be brittle if dropped – not designed for the rigors of outside use.
