    Subpanel protection
    If I run a 10-3 with ground direct burial to a panel in a small garage and use it to split into to 30 amp curcuits what breaker do I need in my main electrical panel feeding the garage panel?

    The breaker in the main protects the wire, so seeing as it is #10 you can use a 30A breaker.

    What are you using 30A breakers for in the garage?

    If this is for one 240 volt 30 amp circuit, why the need for a subpanel?

    Just know you cannot use 30A circuits and breakers for general 15 or 20 amp receptacles and lighting circuits.
