  10. Similarly, attach the black wire of your power line pair of wires we labeled earlier to the “hot” terminal of the “line” section of GFCI. Again check the label of the hot terminal in the line section of GFCI and make sure that we made the connection correct.
  11. Receptacles usually have a yellow sticker on their load terminals in the breaker box. Remove that sticker as now you have to connect these load terminals.
  12. The load side of the receptacles has one white and one black wire identified earlier. Connect the white wire of the load side of the receptacle to the load terminal of the GFCI having silver color and black wire to the hot load terminal of the GFCI.
  13. Now identify the ground wires in the outlet and connect them to the screw of GFCI which is green in color and has a ground label on it.

carefully arrange your wires and make indisputable no connection is loose and slip in everything into the surf box. besides, make certain that the no-load end or any other office line is not touching the ground wires. now finally attach the binding of the panel.
