Advise pls: I have to deal with a weird "in-wall" wiring configuration in my home, in order to make a single pole light switch to work on a particular light. Because of the awkward locations of switch & light, I'm wondering if I can use the configuration in this diagram I've uploaded. **The switch has a neutral connection.... it's a Lutron Caseta (smart switch) Can anyone tell me if: 1- Legal? 2- Safe? 3- Workable? Thanks in advance

I have an older 3-prong receptacle next to my sink and I wanted to replace it with a GFCI. When I took it out of the wall, there are 3 sets of wires. One black and one neutral was attached to top outlet screw terminals. Two black and two neutral wires were attached to bottom outlet screw terminals. The grounds are twisted together and attached to a screw in the box. Initially I put the 1 black / 1 white in the line terminals of the gfci and the others in the load terminals, assuming that was the original setup on the old receptacle. The green light on the gfci came on but it won’t reset and gfci tester in bottom outlet registered nothing. More importantly refrigerator is still off so I’m sure this didn’t work. its a 20a circuit and I think this is the 2nd device because the receptacle on the other side of my sink (in the same circuit) works but none of the other devices do. How do I troubleshoot this? I’d like to have the gfci there and have fridge, dishwasher and other outlets working. if I can’t get gfci to work and go back to 3 prong outlet, I can’t have two wires under 1 terminal, right? So i’d Use pigtails? sorry for the lack of photos - I’m on my phone. thanks!
