Hi all. I have a bathroom fan on a simple switch but wanted to upgrade it to a time. When I pulled the switch out of the wall I found one ground wire, and a singe wire with some of the sheathing removed to loop around the other terminal.
Can I cut the looped wire and connect it to the load / line on the timer? Then I connect the ground to the uncapped ground/neutral on the switch?


Edit: the advice worked.
I put the unlooped black wire with one of the black wires on the timer. I cut the black loop and tied the two wires to another black wire on the timer. I put another grounding wire on the metal box and attached it to ground. Likewise, I pigtailed the neutral bundle and connected to neutral.
It took a few tries to get the box to close correctly since the timer is so big, but it worked out! Thanks again all.
The requirement for everything to have a ground wire is fairly new in the scheme of home construction. Depending on when the house was built, and depending on if everything up to now was done to code, would impact if it's there.
