New to the group here and hoping for solid guidance.
I have a 240v water heater that was removed as the house was converted to a gas exterior unit.
The 30amp supplies the 240v on a 10-2 wire.
What I’m working on is converting this 30amp 240v to a 30amp 120v sub panel.
My thoughts are to replace the main 30amp couple pole with a 30 amp single pole, so that I can wire the sub with this without replacing the 10-2 wire.
The end goal/use for this sub panel is to repurpose the 30amp so that I can add a 20amp breaker that will be dedicated for a crawl space dehumidifier and another 15amp breaker that will be dedicated for the gas tankless water heater now mounted outside.
Question for this group: Do I jump the hot to both hot lugs or can I just connect it to one lug if I only intend on putting both the breakers on one side.
If I don’t have to jump it, can I connect it directly to a single pole 30 amp breaker and connect it directly to the bar to act as a sub switch?
If none of these are advisable, any insight on the next best course of action?
