I got rid of my spa and i am leftwith a 8/3 wire outside. The wire is connected to a 50 amp breaker in my main panel in the house. I want to use the wire to run lights to a gazebo. Can i use the 8/3 wire or do i have to pull the 50 feet of 8/3 out and replace it with a 14/2 wire? Can i leave the 50 amp breaker in and keep the 8/3 wire connecting it to a new out side 4breaker panel to runthe lights from?
