timer connection for single pole switch
I recently purchased a digital timer to control external lights. The lights are currently controlled by single pole single throw switch. Inside the box it only has one hot wire coming in and one going to switch. The problem is that the timer needs neutral connection that I don't have. How do I connect that? I don't feel comfortable connecting this to ground for obvious reasons. It also has another ground connection as well.
Is there another type of timer for single pole single throw switch?
