Procedure : Unscrew the plug top with the help of a screw driver. Remove one of the screws on the wire clamp and loosen the other. Cut away about 50 mm of the outer sheath of the flex, taking care not to damage the insulation on the three separate wires.
Fasten the sheath firmly under the clamp so that the terminal in the plug is not under strain.
Cut the wires to reach about 10 min beyond the appropriate terminal. You would recall from here, that the green, red and black wires are to be attached to the earth, live and neutral terminals, respectively.
Use the wire strippers to remove sufficient insulation to expose enough wire to make the connections taking care not to damage the wires.
Twist the strands of each wire in turn and fit them into the hole or loop them clockwise around the terminal and tighten the screw.
Check that there are no stray 'whiskers' of bare wire which could cause short circuits with in the plug and check that the wires are connected to the correct terminals.
Check that the screws holding the wires in place are tight enough. Refit the plug top with the help of a screw driver.
Draw a diagram showing the connections you have made. You may use colour pencils to make it very clear and, show the plug to your counsellor.
