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.
