Is a main breaker ever required on a subpanel?
This job at my home will have a sub at a detached building and has more than 6 handles.

If the subpanel is in a detached structure and has more than 6 breakers a main disconnect is needed. If the subpanel is in same structure as the main panel then a main breaker is not needed in the subpanel.

A detached building does need to have a disconnect somewhere. The panel does not need to have a main breaker. There could be a separate disconnect on the feeder to the sub panel.

Joe is saying the means of disconnect does not need to be a main breaker in the panel. It can be a disconnect ahead of the panel at the outbuilding.

OK. What i think i read is that 6 handles or less is fine as is. More than that requires a single main, in the box or ahead of the sub somewhere on or in the outbuilding.
