12.3 For a tracker investigated in combination with a remote battery supply intended to be used with the
tracker, only one disconnect device is required to be provided for the battery supply circuit.
13 Supply Connections
13.1 General
13.1.1 A tracker shall have provision fo connection of a wiring system consisting of:
a) Wiring terminals as specified in 131.3 — 13.2.10 or wiring leads as specified in 13.1.3 and 13.3.1 — 13.3.6, and
b) A means for connection of cable or conduit as specified in 13.5.1.
Exception: The requirements described in 13.1.3 — 13.4,3 do not apply to the means for connection to isolated accessible signal circuits complying with the requirements specified in isolated Accessible Signal Circuits, Section 24.
13.1.2 The requirement in 13.1.1 applies to the wiring connection means far ac and dc input and output power Circuits of a tracker intended to be made in the field when the tracker is installed.
13.1.3 A wiring terminal or lead shall be rated and sized for connection to a field wiring conductor having an ampacily based on Table 310.16 of the National Electrical Code, ANSI.NFPA 70, of no less than 125 percent of the RMS or dc current that the circuit carries during rated conditions. For determining the appropriate column in Table 310.16. see 674 (J) and (K).
13.2 WIring termInals
13.2.1 A wiring terminal shall comply with the requirement in 13.1.3 for a wire of each metal for which it is marked. See 64.8.
13.2.2 A wiring terminal shall be provided with a factoiy•installed pressure terminal connector that is securely fastened In place — for example, firmly bolted or held by a screw.
Exception No. 1: A field-installed pressure terminal connector in accordance with 13.2.4 meets the intent of this requirement.
Exception No. 2: A wire-binding screw employed at a wiring terminal intended for connection of a 10 A WG (5.3 mm2) or smaller conductor and having upturned Jugs. a cupped washer, or the equivalent to hold the wire in position meets the intent of this requirement.
13.2.3 A wiring terminal shall be secured in position, by a means other than friction between surfaces, so that it does not turn or shift. This is able to be accomplished by two screws or rivets; by square shoulders or mortises; by a dowel pin, lug, or offset: by a connecting strap or dip fitted into an adjacent part: or by an equivalent method.
Exception: A pressure terminal connector used in accordance with 13.2.4 is able to turn when the spacing complies with Spacings, Section 20, when the connector is oriented in the position resulting in the least spacing between adjacent terminals and also between terminals and dead metal parts.
13.2.4 With reference to Exception No. 1 to 13.2.2, a pressure terminal connector is not required to be factory installed when the conditions in (a) — (e) are met:
a) One or more component terminal assemblies shall be available from the component manufacturer or others and specified In the instruction manual, See 67.4(8) and (C).
b) The fastening hardware such as a stud, nut, boll. spring, or flat washer, and similar hardware, as required for an effective installation, shall be:
1) Provided as part of the terminal assembly,
2) Mounted on or separately packaged with the tracker, or
3) Specified in the instruction manual.
C) The installation of the terminal assembly shall not involve the loosening or disassemb4y of parts other than a cover or other part giving access to the terminal location. The means for securing the terminal connector shall be readily accessible for tightening before and after installation of conductors.
d) When the pressure terminal connector provided in a terminal assembly requires the use of other than a common tool for securing the conductor, identification of the tool and any additional instructions shall be included in the assembly package or with the tracker. See 67.4(D).
e) Installation of the pressure terminal connector in the intended manner shall result in a tracker complying with the requirements of this standard.
13.2.5 A terminal block or insulating base for support of a pressure terminal connector shall comply with the Standard for Terminal Blocks. UL 1059.
