GFCI Outlet Electrical Wiring the Tailed Wiring Method

Installing more than one GFCI at multiple locations

GFCI home wiring - The tailed wiring method is very useful and enables the GFCI protection to be location specific. One example where this is very advantageous is in a two story residence where there is a bathroom downstairs and a bathroom upstairs.

If the circuit was protected by only one GFCI on the downstairs level and second floor bathroom created an accidental trip, the person in the second floor bathroom would require the first floor GFCI to be reset. This method of GFI outlet wiring can be a real disadvantage.

Below you will see some photos of recent home wiring projects that I have selected to help you with your project.

In this home wiring installation you will see how I converted a typical receptacle into a GFCI that will then be operated independently of the other devices downstream on the circuit.
