A1INTRODUCTION1 Scope1.1 These requirements cover wiring systems for use in outdoor locations, field-installed wiring assemblies using off-site manufactured subassemblies for branch circuits, remote-control

20、circuits, signaling circuits, and communication circuits in accessible areas. The products covered under this standard are to be installed in accordance with Article 604 of the National Electrical Code, ANSI/NFPA70.2 Glossary2.1 For the purposes of this standard the following definitions apply.2.2 A

21、CCESSIBLE PART A part that is:a) Located so that it can be contacted by a person; orb) Not recessed the required distance behind an opening.2.3 BRANCH CIRCUIT The circuit conductors between the final over-current device protecting the circuit and the outlet(s).2.4 BRANCH CIRCUIT, MULTIWIRE A branch

22、circuit that consists of two or more ungrounded conductors that have a voltage between them, and a grounded conductor that has equal voltage between it and each ungrounded conductor of the circuit, and that is connected to the neutral or grounded conductor of the system.2.5 CLASS 2 CIRCUIT An isolat

23、ed secondary circuit involving a potential of not more than 30-volt rms maximum 42.4 volts peak open circuit secondary potential under any condition of loading or open circuit by:a) An inherently-limited Class 2 transformer;b) A combination of an isolated transformer secondary winding and a fixed im

24、pedance or regulating network that together comply with the performance requirements for an inherently- limited Class 2 transformer;c) A dry-cell battery having output characteristics not greater than those of an inherently-limitedClass 2 transformer;d) Any combination of (a), (b), and (c) that toge

25、ther comply with the performance requirements for an inherently-limited Class 2 transformer; ore) One or more combinations of a Class 2 transformer and an overcurrent protective device that together comply with the performance requirements for a noninherently-limited Class 2 transformer.A circuit de

26、rived from a line-connected circuit by connecting impedance in series with the supply circuit as a means of limiting the voltage and current is not considered to be a Class 2 circuit.2.6 CONTINUOUS PLUG-IN BUSWAY A continuous plug-in busway is rated at 600V, 40 Amperesor less, has no exposed bus bar

27、s, and is intended for general use, including installation within the reach of persons.2.6 effective February 23, 20112.7 ENCLOSURE A housing which provides a degree of protection against contacting live parts (i.e., connector, conductors, and contacts). The enclosures are constructed of metal, poly

28、meric material, or hybrid (combination of metal and polymer).2.8 ENCLOSURE, ENVIRONMENTAL The portion or portions of a device intended to provide a degree of protection to the contacts, blades, terminals, conductors, and other live parts of the device and of any adjoining devices or components compr

29、ising a complete protective system against outdoor conditions, both when the device is unmated and when it is fully connected to its intended mating device.2.9 FITTING A means of securing conduit, cable, or raceway to an enclosure or box.2.10 INSULATION, BASIC The insulation necessary for the intend

30、ed functioning of the product and for basic protection against the risk of electric shock.2.11 INSULATION, SUPPLEMENTARY An independent insulation provided in addition to the basic insulation to reduce the risk of electric shock in case of breakdown of the basic insulation.2.12 LIMITED POWER SOURCE
