2017 Heartland Mallard M312 bus bar mini breaker amps

[leebmoss]

I need to replace my 2017 m312 bus bar mini breakers. There are 6 mini breakers. From left to right they are: 50-30-30-10- ?-?.
The left 4 all were labeled but the last 2 on the right are not labled. Anyone have any ideas? See pic
Thanks for any help.

The wire sizes may give you a clue as to the amperage the circuit can handle.

12 Volt - Wire Gauge vs. Amps

Maximum current (amps) in a 12V electrical circuit vs. size (AWG) and length of wire.

Information could be on the back of the breakers.
