main overcurrent protection in subpanel

[smallfish]

Is it required by the NEC to provide main overcurrent protection in a sub-panel for feeders?
The feeders in question are fused and supplied from a distribution panel in the basement of a mall and run in pipe 250 feet through a floor to this subpanel that supplies circuits for a kiosk (for lack of a better word, a boutique).

While not IMHO required, not bad practice to do so.

You are not required to have a main breaker in a sub-panel where the feeder feeding the panel has it's overcurrent protective device at the distribution panel.

Even in a detached garage in a dwelling unit?

It would not be a so called sub-panel if a panel were installed in a detached garage.

My head always gets twisted on this one. What is the panel called then? It isn't metered seperately. I'm MORE than willing to look it up! Just need a tiny hint. (Have '05 and '08 right here next to me)

I don't know that it has a name per se but I would call it "the panel in the garage"..:grin: or maybe main feeder panel for detached garage..:smile: :smile:

Remember sub panel is not in the NEC either.

A panel in a garage needs to have a disconnecting means at the garage (See 225.31). 225.31 is not a requirement for an overcurrent device at the detached garage just a disconnecting means which could be a main breaker but can also be done by the use of a non-fused disconnect.

I agree that the term "sub-panel" is confusing especially due to the fact that the NEC doesn't use the term.

I try to avoid the use of the term "sub-panel" and just call it either a power panel or lighting and appliance panel.

Even there the panel is not required to have a main breaker, but the building is required to have a disconnect. The easiest way to provide the required building disconnect is to install a main in the panel.

Sure as long as 225.32 are satisfied....

I have a pic of a 100amp main lug panel in a detached garage that has no disconnect and the there is no connector were the feeders come in the back of the panel, just pipe that ends in the wall, the wire pass through some insulation, 1/2" osb, and through a open KO. Its fed by undersized USE too

Best part is it passed inspection. Sticker and all.

The electrical inspector must have been sick so they sent the plumbing inspector out instead.
