Panel to Garage sub-panel. How many amps can my sub-panel hold? (You are not my electrician.)
I will be hiring a licensed electrician, I’m just curious as to what to expect.

The main house electrical service panel is connected to a sub panel in a detached garage.
The circuit on the main panel feeding the garage has a two pole breaker labeled 30 amps.
The garage sub panel has a one 20 amp circuit and one 15 amp circuit. There is room on the panel to add two more circuits.
My questions are:
It is my understanding that the circuit to the garage can be either a single 240 volt or two 120 volt. Is my understanding correct?
If this is correct, how many amps can I add to the garage sub-panel if it’s single 240?
How many amps can I add to the garage sub-panel if it’s two 120?
If this is completely wrong, let me know.
