Sample text

A receptacle is a contact device installed at the outlet for the connection of an attachment plug. A single receptacle is a single contact device with no other contact device on the same yoke. A multiple receptacle is two or more contact devices on the same yoke. Service. The conductors and equipment for delivering electric energy from the serving utility to the wiring system of the premises served. Service Cable. Service conductors made up in the form of a cable. Service Conductors. The conductors from the service point to the service disconnecting means.

Overcurrent. Any current in excess of the rated current of equipment or the ampacity of a conductor. It may result from overload, short circuit, or ground fault. NATIONAL ELECTRICAL CODE 70–37 FPN: A current in excess of rating may be accommodated by certain equipment and conductors for a given set of conditions. Therefore the rules for overcurrent protection are specific for particular situations. Overload. Operation of equipment in excess of normal, full-load rating, or of a conductor in excess of rated ampacity that, when it persists for a sufficient length of time, would cause damage or dangerous overheating.

Can include varying amounts of combustible gases, depending on the askarel type. Attachment Plug (Plug Cap) (Plug). A device that, by insertion in a receptacle, establishes a connection between the conductors of the attached flexible cord and the conductors connected permanently to the receptacle. Authority Having Jurisdiction. The organization, office, or individual responsible for approving equipment, materials, an installation, or a procedure. Accessible (as applied to equipment). Admitting close approach; not guarded by locked doors, elevation, or other effective means.
