Smile Seeing behind drywall

How does one know where a branch circuit begins if one wants to put a gfi there to protect everything upstream? Are there any effective instruments out there that will aid in tracing the route of romex behind drywall? Am reading the archives and would like to know if Goodrich is alive and well? What a brilliant electrician, teacher and person he appears to be. Thanks all. Am getting a wonderfull education here.

Easiest thing is trial and error. You could try and find the receptacle(s) in question closest to the main panel and disconnect the branch circuit and see if the rest downline go out. Thats how I did my bathroom(s).

Thats the best way, Time consuming yes.
Another option is a GFCI breaker. This depends on what the ckt carries. If just general purpose recepticales and lights...$27 and it's done.
