I have always been under the impression that a detached garage at a dwelling does not require a main disconnect at the garage eventhough it has a panel that has more than 6 branch breakers.
However, one of my students said that 225.32 applies.

but my defense was article 408.36 the main overcurrent device for a panel board can be located within or at any point on the supply side of the panel board.

The more I read 225.32 the more i agree with him that a main disconnect is required st the detached garage.

Please give me your comments.

Thanks.
