Terminal Blocks - Component
The devices covered under this category are incomplete in certain constructional features or restricted in performance capabilities and are intended for use as components of complete equipment
submitted for investigation rather than for direct separate installation in the field. THE FINAL ACCEPTANCE OF THE COMPONENT IS DEPENDENT UPON ITS INSTALLATION AND USE IN COMPLETE
EQUIPMENT SUBMITTED TO UL.

GENERAL
This category covers assemblies of wiring terminals and supporting blocks intended to provide a means for the connection of wiring. These terminal blocks may employ terminal connectors, wire-binding
screws, quick-connect terminals and similar friction fit terminals, which are intended for factory-wiring and/or field-wiring connections.
This category also covers protective conductor terminal blocks (PCTB) intended for connecting protective earthing (grounding) conductors to supports, such as mounting rails and the like. A PCTB is
marked with the international symbol for ground, "G,""GR,""GND,""Ground,""Grounding" or the like. In addition, the insulation of a partially insulated PCTB is colored green or green/yellow.
This category also covers fuse terminal blocks that have a fuse carrier and are intended to accept supplemental fuses (miscellaneous, miniature and micro). Fuse terminal blocks provide supplemental
protection in end-use equipment to provide protection for components or internal circuits. They are not suitable for branch or feeder circuit use.

USE
The following performance levels include ratings for voltage, current, wire size and type, torque (if applicable), suitability for factory wiring only or field wiring, and use group in order to facilitate
investigation of their use in end-product applications. The following statements explain the tabular information:
Wire Range — The wire size or range of wire sizes for which a terminal block has been investigated. Unless clearly marked "Solid,""SOL,""Stranded" or "STR" for a given wire size, wire range or wire
combination, conductors in the range 30-10 AWG are both solid and stranded, and 8 AWG and larger are for stranded wire only. Terminal blocks generally accommodate a single conductor under aclamping mechanism unless otherwise identified, such as with the number of conductors located parenthetically in front of the wire size or range. Some terminal blocks may have a single conductor wire
range as well as a multiple conductor wire range. This may be identified by separate line items in the tabular information in the individual Recognitions. Terminal blocks, without insulation displacement
connections, that are rated for solid copper conductors may also be used with stranded copper conductors of the same wire gauge when the stranded copper conductors are prepared by termination toa certified bare or covered ferrule.
Wire Type — The conductor material for which the terminal block has been investigated. "CU" represents copper wire only, "AL" represents aluminum wire only. "AL-CU" or "CU-AL" indicates use withaluminum and copper conductors, but not intermixed. The "7" or "9" associated with the wire type represents the temperature rating (75 or 90°C) of the wire connector.
Factory and/or Field Wiring (FW) — These terminal blocks are rated for: Code 1, factory wiring only, or Code 2, both factory and field wiring. The suitability of the connections (including spacings
between factory connectors) shall be determined in the end-use application.
Unless noted with a "CA 4" in the last column, a terminal connector suitable for field wiring has been investigated to UL 486A-486B, "Wire Connectors."
When Code 1 and Code 2 terminals are intermixed on the same terminal block, both codes will be used with suitable indication for which terminal each code applies, i.e., 1/2.

Torque (TQ) — The tightening torque(s) for a field-wiring pressure terminal connector other than a wire-binding screw, stud and nut type, or quick-connect type. If rated for factory wiring, this torque isonly the manufacturer's recommended value.
Voltage (V) — Terminal blocks have voltage ratings for which they have been found acceptable. A terminal block may have several voltage ratings that relate to the different use groups and spacinglevels as tabulated under "Use Group."
Current (A) — A maximum value of per-pole current for which the terminal block has been found acceptable.
Short-circuit-current Rating (SCCR) — Terminal blocks are considered suitable for use on a circuit capable of delivering not more than the stated SCCR at the maximum voltage specified when
protected by the max ampere and Class of overcurrent protective device noted in the individual Recognitions. Short-circuit-current ratings may be marked on the terminal block or on instructions
provided with the terminal block. Short-circuit-current ratings have been determined based on the terminal block's use within the minimum enclosure sizes as specified in Condition of Acceptability #6.
Use Group (UG) — The type of end-use application for which the specified voltage and spacing level applies.
Conditions of Acceptability (CA) — The limitations and conditions for end-product use based on the investigation of the terminal block. See additional details under CONDITIONS OF ACCEPTABILITY
below.
