    How do you wire a new GFI from start with a light switch? I have a GFI, a light fixture and a light switch. There is a main feed from breaker box a wire for light and a switch to add. How do I make a complete circuit.

    I’m currently updating a small bathroom in my home and the bathroom light also has an outlet which is also connected to the switch. How do I convert that to a GFI while also replacing the light fixture to a bath fan/light combo? Thank you.

    • Dave Rongey says:

      Hi Rhonald,
      To provide GFCI protection for the outlet on the light fixture be sure that the supply circuit has GFCI protection. This is typically accomplished when there is a GFCI outlet in the bathroom which provides power to the light fixture, or the circuit breaker which supplies power is a GFCI circuit breaker.
