If a single 120v branch circuit is installed to a residential storage building where they just want a light and a receptacle, is a 1p snap switch required as a disconnect before it gets to the 1p snap switch for the light and receptacle power?

This seems odd and confusing.

The HO would probably mistake the disconnect for the storage shed as just another light switch, shut it off, and in turn kill the power to the receptacle whether they needed the light on or not.

Yes a means is required to disconnect all power to a separate structure even when there is only one branch circuit. Could be a properly rated snap switch. The switch could be located in an obscure location on the outside to avoid confusion.

They would hate my storage buildings........... ;)
 
I don't believe a single circuit is compliant anymore unless it is a multiwire branch circuit.

210.52(G) Basements, Garages, and Accessory Buildings. For
a one-family dwelling, at least one receptacle outlet shall be
installed in the areas specified in 210.52(G)(1) through (3).
These receptacles shall be in addition to receptacles required
for specific equipment.
(1) Garages. In each attached garage and in each detached
garage with electric power. The branch circuit supplying
this receptacle(s) shall not supply outlets outside of the
garage. At least one receptacle outlet shall be installed for
each car space.

What am I missing here? Why wouldn't the individual circuit breaker be this disconnect?

Article 225 requires the disconnecting means for the accessory building to be installed either inside or outside of the building, at an accessible location nearest the point of entrance of the conductors.

How so? It is indicating on/off-open/closed.

The on/off markings don't provide any indication as to whether the device is open or closed, just which button to push to turn it on or off.

Also, how would it be manually opened in the event of a power failure?

And finally, its not a circuit breaker, molded case switch, general use switch or snap switch. Whether its an "other approved means" would depend on who's doing the approving, I guess.

As far as on/off-open/closed, many discos only say on/off.

Its not the wording on/off vs open/closed that is relevant. The disconnecting means must provide visual indication of the switch position. A disconnect or general purpose switch does that, the gfi device does not.

Well phooey, it do say dat!

(D) Indicating. The building or structure disconnecting
means shall plainly indicate whether it is in the open or
closed position.

I am gonna go play in a different thread, getting too beat up in this one.:)

I don't see any requirement for a multiwire branch circuit there?

The requirement is not for a multi wire circuit but you cannot have one circuit. One would normally run a multiwire branch circuit because they would satisfy code as a single circuit to a detached garage
