Good Day
Sure it's here somewhere?
Can a disconnect by itself be considered a service?
Meaning fuses grounding meter base no branch panel and no others equipment.
Thanks please direct me to location.
 
If you are asking if a meter base and a main disconnect is a service then I would say yes. The service is really the connecting point bet power company and the premise wiring. The meter and the disconnect are service equipment.

Service. The conductors and equipment for delivering electric
energy from the serving utility to the wiring system of the premises
served.

article 100:
Service Equipment. The necessary equipment, usually consisting of a circuit breaker(s) or switch(es) and fuse(s) and their accessories, connected to the load end of service conductors to a building or other structure, or an otherwise designated area, and intended to constitute the main control and cutoff of the supply.
Service equipment may consist of circuit breakers or fused switches that are provided to disconnect all ungrounded conductors in a building or other structure from the service- entrance conductors. It is important to understand that individual meter socket enclosures are not considered service equipment according to 230.66. A case could be made that potential and current transformer cabinets associated with utility meter enclosures are also excluded from the definition of service equipment. The disconnecting means at any one location in a building or other structure is not allowed to consist of more than six circuit breakers or six switches and is required to be readily accessible either outside or inside nearest the point of entrance of the service-entrance conductors. Requirements for service conductors outside the building are in 230.6 and those for disconnecting means are throughout Article 230, Part VI.
so then ou go to 230.70... for types of disconnects allowed, etc...

A service is defined in Article 100 and covered in Article 230.

At a minimum, service entrance conductors into a disconnecting means, grounding and bonding, and overcurrent protection can constitute a service. A meter base is a utility requirement, NEC has no interest in its existence regarding the definition and consist of a service.
 
Service supplying a single load (maybe a pumping station) can have just one disconnect that serves as both the service disconnecting means and the branch circuit overcurrent device.

I always considered the service to be what the POCO supplies, that the premises wiring and utilization equipment get their power from.
As in "POCO provided a 200A service, at a cost of $XX".
The service point is the arbitrarily designated (by POCO and maybe AHJ) point where POCO responsibility stops and the customer's starts, even though POCO may also still impose conditions on the wiring downstream of the service point. The service point is also generally considered to be the designated point where NESC (or other POCO adopted standard) jurisdiction ends and NEC jurisdiction starts.
The service point is at or somewhere upstream of the service disconnect (which is fully defined in the NEC).

The NEC puts limits on how many services there can be to a building, but more than one set of service conductors from the secondary of a single POCO transformer could be either a single service or multiple services. The NEC does not specify how that distinction is made.
Two sets of service conductors (not paralleled) from two different POCO transformers/transformer-sets would seem to me to always be two services, but....

Multiple sets of conductors from same source to a building/structure is one service, they must all end up in same location at the building/structure with some exceptions like for fire pumps. If not at same location then it is either multiple services (not permitted) or improper application of a single service. There may be times where multiple occupant buildings or even single occupant but with proper fire barriers can be considered multiple buildings and then one service per source is allowed per building.

Different voltage, frequency, or other characteristics will allow additional services per building, for each source, or even if the load capacity is more then the POCO will supply through one service.
 
This service as some have stated.
Was turned down by me , due to the fact that there was a hole in the back of disconnect and hole in concrete wall with nothing in it. I did not grow up with a disconnect as service, still something new most days. THANKS
