Question Quick subpanel question

I am installing a small 60 A, 240V subpanel in my attached garage. The subpanel is on the outside wall of the room the main breaker panel is in.

Do I need a main breaker for the subpanel if it is protected by a 60A breaker in the main box?

A subpanel in an attached structure does not require a 'main'.

You may find that it is _cheaper_ to buy a 100A panel kit with a main breaker at one of the 'big box' stores than a 60A main lug panel. It is totally fine to feed a 100A rated panel with a 60A feeder protected by a 60A breaker.

If the subpanel is in another room from the main panel you may find it useful to have the ability to kill the power locally that a main breaker would provide...
