Question

Panel type?


If I want a sub panel with more than 6 spots in my attached garage, should I use a main breaker panel or a main lug panel? And can I use either or? I have read if you have more than 6 breakers in your sub. It cannot be main lug. Is this true?

If the garage is attached, you do not need a main breaker panel out there.

You can install the largest panel that you want with main lugs only.

KB - If the structure is not attached, is a main breaker required?

You will need a mainbreaker if the garage is detached.

You will need a disconnecting means. The easiest way to accomplish this is to use a main breaker panel.

Detached structures have pretty much the same requirements as a separate service the only thing missing is the meter.

I live in a rural house. Meter is on a pole and a service disconnect sits immediately below the meter. After the disconnect, the service conductors go back up the pole, and are then suspended overhead to the house where they enter the panel. There is not a main breaker in the panel.

Does this violate the NEC?

No. The service disconnect is at the pole. The house has a subpanel.

Yet the house is not attached to the pole...so why the difference? I'm struggling with the attached/not attached requirements.

EDIT: why can't the main panel serve as the disconnecting means for the panel located in a detached garage?

Because the NEC requires a service disconnect at the detached garage.

And thus the root of my earlier question about the logic of the requirement, not the basis of the requirement.

Over the last several code cycles the NEC requirements for detached structures has been tightened up. Currently, detached structures have the same requirements for service requirements as the primary structure, plus the insulated neutral. Minus the meter enclosure. A grounding electrode system has to be established (ground rods). One thing that has to be observed is that the equipment has to be "suitable for use as service equipment". The panel installation instructions will indicate how that is to be done.

I don't see anything in the thread stating where you will be drawing power to feed your detached garage. Are you planning to draw from the house panel or the pole disconnect?
