I currently have a switched and un-switched hot running underground in conduit sharing the same neutral and ground. Its important to note that they are both on the same circuit. Basically I have 4 wires (switched Hot, UnSwitched Hot, 1x Neutral, and 1 Ground). The Switched Hot powers 3 Lamps in my back yard and the unswitched hot powers a series of outlets in a shed.
Currently the circuit is not protected by GFCI. I have access to a junction box before the conduit goes underground. Can I effectively install 2X GFCI switches and tie the Switched and Un-Switched Hots to their respective GFCI as normal and tie the two outlets in series with the same neutral.
Im wondering if this setup may confuse the GFCIs since the 1X neutral will carry the current back from both Switched and un-switched hots in the event that both are drawing power at the same time.
