i have a shed that had a window ac in it.It was fed with 10-2 wire with a 30 amp 220 volt breaker from the main panel from the house. I want to put in a sub panel ,the sub panel i have is a 125 amp 2 main lug with neutral bar and ground bar can i use the 10-2 wire to wire the sub panel? Ill only be hooking up a 115v ac and a overhead light and one outlet.
