Readily accessible--Capable of being reached quickly for operation, renewal, or inspections,

without requiring those to whom ready access is requisite to climb over or remove obstacles

or to resort to portable ladders, chairs, etc. (See "Accessible.")

Receptacle--A receptacle is a contact device installed at the outlet for the connection of a

single attachment plug. A single receptacle is a single contact device with no other contact

device on the same yoke. A multiple receptacle is a single device containing two or more

Receptacle outlet--An outlet where one or more receptacles are installed.

Remote-control circuit--Any electric circuit that controls any other circuit through a relay or an

equivalent device.

Sealable equipment--Equipment enclosed in a case or cabinet that is provided with a means

of sealing or locking so that live parts cannot be made accessible without opening the

enclosure. The equipment may or may not be operable without opening the enclosure.

Separately derived system--A premises wiring system whose power is derived from

generator, transformer, or converter winding and has no direct electrical connection, including

a solidly connected grounded circuit conductor, to supply conductors originating in another

system.

Service--The conductors and equipment for delivering energy from the electricity supply

system to the wiring system of the premises served.

Service cable--Service conductors made up in the form of a cable.

Service conductors--The supply conductors that extend from the street main or from

transformers to the service equipment of the premises supplied.

Service drop--The overhead service conductors from the last pole or other aerial support to

and including the splices, if any, connecting to the service--entrance conductors at the

building or other structure.

Service-entrance cable--Service-entrance cable is a single conductor or multiconductor

assembly provided with or without an overall covering, primarily used for services and of the

following types:

Type SE, having a flame-retardant, moisture-resistant covering, but not required to have

inherent protection against mechanical abuse.

ii. Type USE, recognized for underground use, having a moisture-resistant covering, but not

required to have a flame-retardant covering or inherent protection against mechanical

abuse. Single-conductor cables having an insulation specifically approved for the purpose

do not require an outer covering.

Service-entrance conductors, overhead system--The service conductors between the

terminals of the service equipment and a point usually outside the building, clear of building

walls, where joined by tap or splice to the service drop.
