I have an old air compressor run by an old 3HP GE electric motor being powered outside from a 20A breaker in a subpanel. The air compressor is hardwired into the breaker.

I want to install some way of either remotely turning the compressor on and off, mostly so that I dont need to go throw the breaker every morning and evening.

I'm looking for suggestions on how to accomplish this...

Yup,

Power from breaker to timer then to compressor.

Those are very reliable timers. I know some facilities that use them for the parking lot lights and they're well over 20 years old.

You can use the same neutral that your compressor uses.
I'm gonna definitely show my ignorance here guys, but if someone could point me to an example of that I would need to look for and maybe a real simple explanation for the wiring involved?

Wherever the compressor connects now is 120V.
It has the hot and the neutral in it. Set a box there.

Install an occupancy sensor and receptacle. Done.

You need to find a sensor properly rated for the motor load. It isn't like turning on a couple of lights.

The timer is rated for the motor.
