STEP 6: Lose the screw’s terminals on the plug with the help of a screwdriver. Now connect the cord wires carefully. Connect the active wire (black or brown in color) to the brass terminal, Neutral wire (blue or white in color) to the silver terminal and Earth wire (yellow or green in color) to the ground screw.
