  5. When connecting the wires, make sure that the neutral wire is connected to the silver terminal while the hot wire is connected to the brass terminal. This will ensure the proper functioning of the device.
  6. Double-check your connections before restoring power in order to be sure that everything is wired correctly and safely. The connection should be secure, and all wires should be correctly aligned.
  7. Once the wiring is complete, you can restore power to the device by switching on the circuit breaker in the main box. Be sure to keep your hands and any other objects away from the switch once it’s been switched on to avoid any shocks or electrocution hazards.
Wear Protective Gear When Working

Following these safety precautions will help ensure that your wiring project is successful and safe.
