Compliance with

27、these requirements does not assure that the terminal blockis suitable for use as a component of an end product.1.2 These requirements cover terminal blocks rated 1500 volts or less.1.3 These requirements also cover protective conductor terminal blocks (PCTB) used to make theelectrical and mechanical

28、 connection between conductors or between conductors and a fixing supportsuch as a mounting rail. A PCTB is not required to be insulated.1.4 These terminal blocks are intended to permanently support and insulate wire terminations and jointsfrom each other, and from the surface on which the terminal

29、block is mounted, where the absence of suchsupport or insulation presents a risk of fire, electric shock, or injury to persons.1.5 The acceptability of a terminal block in any particular application depends upon its suitability forcontinued use under the conditions that prevail in actual service. Ac

30、cordingly, for a particular applicationa terminal block may be affected by the requirements for the equipment in which it is used, and it may benecessary to additionally evaluate that terminal block for features or performance characteristics that arenot specified in this standard.1.6 Terminal block

31、s employing types of connecting means not covered by this standard such as those inwhich conductors are secured to the terminals by means of a special tool can be evaluated under thisstandard but may require separate investigation.1.7 These requirements do not cover field installed power distributio

32、n blocks intended to distribute powerin a building to separate units such as apartments, separate heaters, and air conditioning units. Powerdistribution blocks are investigated to Subject 1953, Outline of Investigation for Power Distribution Blocks.2 Glossary2.1 For the purpose of this standard the

33、following definitions apply.2.2 FACTORY WIRING The connection of a wire in the end application under controlled conditions,usually at a manufacturers location.2.2 revised September 13, 20042.3 FIELD WIRING The connection of a wire, which is made in the field and that is subjected to therequirements

34、for a terminal for field wiring as specified in this standard and the National Electrical Code,NFPA 70.2.3 revised September 13, 20042.4 INSULATION PIERCING OR DISPLACEMENT CONNECTOR A connector for the connectionand possible disconnection of one conductor or the interconnection of two or more condu

36、OR FURTHER REPRODUCTION ORDISTRIBUTION WITHOUT PERMISSION FROM UL2.5 POST CONNECTOR A connector utilizing a post (solderless wire wrap and similar for example)onto which one or more conductors are secured by means of a tool.2.6 PREPARED CONDUCTOR A conductor, the strands of which are soldered or tin

37、ned; or the endof which is fitted with a cable lug, eyelet, quick-connect, ring terminal, spade terminal, or similarcomponent, prior to insertion into the terminal.2.7 PROTECTIVE CONDUCTOR TERMINAL BLOCK (PCTB) A device with one or more clampingunits for connecting or joining protective conductors (

38、Protective Earthing (PE) conductors) or connectingsuch conductors to the support for the clamping units. The clamping units can be secured with screw-or screwless-type fixing means. Examples of supports are mounting rails, sheet metal cut-outs, ormounting plates. A PCTB is either uninsulated, non-is

39、olated, or isolated See (a) and (b). Operatinginsulation is not necessary as a PCTB is intended to be at ground potential.a) ISOLATED PROTECTIVE CONDUCTOR TERMINAL BLOCK A protective conductorterminal block that provides insulation from live parts of other terminal blocks, adjacent poles ofthe same

40、terminal block, or other devices and isolation from the support. It does not haveprovisions for path 2-2 of Figure 50.1. It uses path 1-1 only.b) NON-ISOLATED PROTECTIVE CONDUCTOR TERMINAL BLOCK A protective conductorterminal block that provides insulation from live parts of other terminal blocks, a

41、djacent poles ofthe same terminal block, or other devices, but does not provide isolation from the support itself.It is mechanically and electrically attached to its support, path 2-2 in Figure 50.1. It may or maynot have path 1-1.2.8 TERMINAL CONNECTOR A device that establishes the connection betwe

42、en two or moreconductors or between one or more conductors and a terminal by means of mechanical pressure.2.8 revised September 13, 20042.9 SEPARABLE TYPE CONNECTORS Connectors consisting of separable, mating members thatcan be readily engaged or disengaged without the use of tools.a) Quick Connect

45、n unprepared conductor is looped around a stud and retained by a nut; orb) A prepared conductor is assembled to a stud and retained by a nut.2.13 TERMINAL BLOCK A terminal block is a rigidly mounted device that is composed of aninsulated base with barriers having one or more electrically conductive

46、members. Each electricallyconductive member serves as a junction to electrically connect two or more conductors and alsoprovides means to individually connect or disconnect conductors. The device can be a sectional or one-piece design.2.14 UNPREPARED CONDUCTOR A conductor which has been cut and the

47、insulation of which hasbeen removed for insertion into a terminal. The conductor end is bare. The conductor in an insulationpiercing or displacement connector is considered to be unprepared.2.15 WIRE BINDING SCREW CONNECTOR A connector that uses a binding head screw, with orwithout a flat ring or lo
