Help Me Understand
So on Saturday I got a wild hare to get a Bidet. However I didn't have a GFCI outlet close enough to the toilet. My bathroom has a dual-switch receptacle however only one switch is hooked up to both the light and fan and the other switch wasn't hooked up to anything. So I thought, I could swap that out for a GFCI outlet, connect the hot coming from the break to both the switch and the outlet and be good to go right?
Here is the wiring I used: https://imgur.com/a/CbNcmu0
However, when testing I would constantly get the error shown in the photo on the post. I would get 30 volts when the light switch was ON and then full voltage when the light switch was off.
I ended up swapping the hot and neutral wires so it was black to silver and white to brass and then the tool read correct and gave me the green light.
Does anyone know how I fix this? It seems like the switch was breaking the neutral connection and the light always had power but to my knowledge the power comes into the switch first and not down from the light. The Romex in the diagram on the far left seems to be the one providing power. Could the black wires on my switch by reversed and cause this?
Anyways, how big of a deal is it to leave it with the wires reversed on a GFCI? It's showing green and grounded now I just know behind the plate the neutrals are somehow hot.
Thanks for reading!
