I have one of those small fridges plugged into a 120v 15 amp circuit. It has been there for at least 15 years.

Mini-fridges typically draw between 30-70 watts, almost nothing compared to a power tool. I typically try and put less-durable devices (e.g. consumer electronics) on circuits that don’t see major surges or spikes. Turning a large motor on or off can generate surges/sags/spikes in the branch circuit that it’s being fed by. I would never put a computer on the same circuit as a table saw, for example.

So find the circuit that has the least number of large motors using it and put your fridge on that.

I would put it on a separate breaker, or off the lighting circuit, but on the “hot” side of the light switch.

The lightswitch for the shop lights is only about 8 feet from the fridge, just inside the mudroom door. As long as the wife doesn’t mind me making a hole and fishing the line through into the garage and under the steps and landing, it shouldn’t be too tough to use that circuit starting from before the switch. I think that is the plan. Good thinking to keep the fridge off the “bigger motors” circuit.
