I have an existing 220V circuit running to my garage using 10-3 with ground wire. I want to convert this circuit to 110V adding a subpanel to the garage and run to recepticles. There will be a freezer and refrigerator.
Do I use a 30 amp double pole circuit breaker at the main panel and run neutral, red, black and ground to the subpanel?
How many 20 amp circuits can I add to the subpanel. If only one, can I add a 20 and a 15 amp?
I know an alternative is converting to 110 V single pole breaker at the main panel with only 1 110V 20 amp circuit, but is it enough for the freezer, refrigerator and more recepticles.
